## Basiese Inligting
|
|
|
|
**Post Office Protocol (POP)** word beskryf as 'n protokol binne die domein van rekenaarnetwerke en die Internet, wat gebruik word vir die onttrekking en **herwinning van e-pos vanaf 'n afstandsposbediener**, wat dit beskikbaar maak op die plaaslike toestel. Geleë binne die toepassingslaag van die OSI-model, stel hierdie protokol gebruikers in staat om e-pos te haal en te ontvang. Die werking van **POP-kliënte** behels tipies die totstandbrenging van 'n verbinding met die posbediener, die aflaai van alle boodskappe, die stoor van hierdie boodskappe plaaslik op die kliëntstelsel, en daarna die verwydering daarvan van die bediener. Alhoewel daar drie weergawes van hierdie protokol is, is **POP3** die mees algemeen gebruikte weergawe.

**Standaard poorte:** 110, 995(ssl)

```
|
|
PORT STATE SERVICE
|
|
110/tcp open pop3
|
|
```
|
|
## Enumerasie
|
|
|
|
### Banner Grabbing
|
|
```bash
|
|
nc -nv <IP> 110
|
|
openssl s_client -connect <IP>:995 -crlf -quiet
|
|
```
|
|
## Handmatig
|
|
|
|
Jy kan die opdrag `CAPA` gebruik om die vermoëns van die POP3 bediener te verkry.
|
|
|
|
## Geoutomatiseerd
|
|
```bash
|
|
nmap --script "pop3-capabilities or pop3-ntlm-info" -sV -port <PORT> <IP> #All are default scripts
|
|
```
|
|
Die `pop3-ntlm-info` plugin sal 'n paar "**sensitiewe**" data (Windows weergawes) teruggee.

POP commands:
|
|
USER uid Log in as "uid"
|
|
PASS password Substitue "password" for your actual password
|
|
STAT List number of messages, total mailbox size
|
|
LIST List messages and sizes
|
|
RETR n Show message n
|
|
DELE n Mark message n for deletion
|
|
RSET Undo any changes
|
|
QUIT Logout (expunges messages if no RSET)
|
|
TOP msg n Show first n lines of message number msg

## Watter Wette
|
|
|
|
POP-bedieners met die instelling **`auth_debug`** geaktiveer, sal die logs wat gegenereer word, verhoog. As egter **`auth_debug_passwords`** of **`auth_verbose_passwords`** as **`true`** gestel is, kan wagwoorde ook in duidelike teks in daardie logs geregistreer word.

|
|
Post Office Protocol (POP) is described as a protocol within the realm of computer networking and the Internet, which is utilized for the extraction and retrieval of email from a remote mail server**, making it accessible on the local device. Positioned within the application layer of the OSI model, this protocol enables users to fetch and receive email. The operation of POP clients typically involves establishing a connection to the mail server, downloading all messages, storing these messages locally on the client system, and subsequently removing them from the server. Although there are three iterations of this protocol, POP3 stands out as the most prevalently employed version.
