## Basic Information
|
|
|
|
IRC, initially a **plain text protocol**, was assigned **194/TCP** by IANA but is commonly run on **6667/TCP** and similar ports to avoid needing **root privileges** for operation.
|
|
|
|
A **nickname** is all that's needed to connect to a server. Following connection, the server performs a reverse-DNS lookup on the user's IP.
|
|
|
|
Users are divided into **operators**, who need a **username** and **password** for more access, and regular **users**. Operators have varying levels of privileges, with administrators at the top.
|
|
|
|
**Default ports:** 194, 6667, 6660-7000
|
|
|
|
```
|
|
PORT STATE SERVICE
|
|
6667/tcp open irc
|
|
```
|
|
|
|
## Enumeration
|
|
|
|
### Banner
|
|
|
|
IRC can support **TLS**.
|
|
|
|
```bash
|
|
nc -vn <IP> <PORT>
|
|
openssl s_client -connect <IP>:<PORT> -quiet
|
|
```
|
|
|
|
### Manual
|
|
|
|
Here you can see how to connect and access the IRC using some **random nickname** and then enumerate some interesting info. You can learn more commands of IRC [here](https://en.wikipedia.org/wiki/List\_of\_Internet\_Relay\_Chat\_commands#USERIP).
|
|
|
|
```bash
|
|
#Connection with random nickname
|
|
USER ran213eqdw123 0 * ran213eqdw123
|
|
NICK ran213eqdw123
|
|
#If a PING :<random> is responded you need to send
|
|
#PONG :<received random>
|
