194,6667,6660-7000 - Pentesting IRC
Support HackTricks and get benefits!

Basic Information

IRC was originally a plain text protocol (although later extended), which on request was assigned port 194/TCP by IANA. However, the de facto standard has always been to run IRC on 6667/TCP and nearby port numbers (for example TCP ports 6660–6669, 7000) to avoid having to run the IRCd software with root privileges.
For connecting to a server it is required merely a nickname. Once connection is established, the first thing the server does is a reverse-dns to your ip:
It seems that overall there are two kinds of users: operators and ordinary users. For logging in as an operator it is required a username and a password (and in many occasions a particular hostname, ip and even a particular hostmask). Within operators there are different privilege levels wherein the administrator has the highest privilege.
Default ports: 194, 6667, 6660-7000
PORT STATE SERVICE
6667/tcp open irc

Enumeration

IRC can support TLS.
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.
#Connection with random nickname
USER ran213eqdw123 0 * ran213eqdw123
NICK ran213eqdw123
#If a PING :<random> is responded you need to send
#PONG :<received random>

You can, also, atttempt to login to the server with a password. The default password for ngIRCd is 'wealllikedebian'.
PASS wealllikedebian
