# Internet Relay Chat Probe (IRCP)
![](.screens/ircp.png)
A robust information gathering tool for large scale reconnaissance on [Internet Relay Chat](https://en.wikipedia.org/wiki/Internet_Relay_Chat) servers, made for future usage with [internetrelaychat.org](https://internetrelaychat.org) for public statistics on the protocol.
Meant to be used in combination with [masscan](https://github.com/robertdavidgraham/masscan) checking **0.0.0.0/0** *(the entire IPv4 range)* for port **6667**.
The idea is to create a *proof-of-concept* documenting how large-scale information gathering on the IRC protocol can be malicious & invasive to privacy.
## Order of Operations
First, an attempt to connect using SSL/TLS on port 6697 is made, which if it fails, will fall back to a standard connection on port 6667.
Once connected, server information is gathered from `LUSERS`, `VERSION`, `LINKS`, `MAP`, `ADMIN`, `MOTD`, `LIST`, replies.
An attempt to register a nickname is then made by trying to contact NickServ.
Next, every channel is joined with a `WHO` command sent & every new nick found gets a `WHOIS`.
## Collected Information
All of the raw data from a server is logged & stored. The categories below are stored seperately & hilight the key information we are after:

## Todo
* Capture `IRCOPS` & `STATS p` command outputs
2023-05-26 01:22:42 +00:00
* Built in identd
* Checking for IPv6 availability *(SSL= in 005 responses may help verify IPv6)*
2023-05-25 20:03:39 +00:00
* Random nick changes for stealth on larger networks
