{% endhint %} ## 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 openssl s_client -connect : -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 : is responded you need to send #PONG : VERSION HELP INFO LINKS HELPOP USERCMDS HELPOP OPERCMDS OPERATOR CAPA ADMIN #Admin info USERS #Current number of users TIME #Server's time STATS a #Only operators should be able to run this NAMES #List channel names and usernames inside of each channel -> Nombre del canal y nombre de las personas que estan dentro LIST #List channel names along with channel banner WHOIS #WHOIS a username USERHOST #If available, get hostname of a user USERIP #If available, get ip of a user JOIN #Connect to a channel #Operator creds Brute-Force OPER ``` You can, also, atttempt to login to the server with a password.
