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.
