TCP 994
Synopsis
- TCP port 994 is officially assigned to IRCS (Internet Relay Chat over SSL/TLS).
- Real-world IRC server software such as UnrealIRCd, InspIRCd, and ircd-hybrid commonly support a TLS listener on 994, and many deployments enable it as a legacy SSL port.
- Popular IRC clients including mIRC, HexChat, Irssi, and WeeChat can connect to IRC servers on port 994 when using SSL/TLS.
- Associated with hacking: IRC-based botnets sometimes use encrypted IRC on ports like 994 to conceal command-and-control traffic.
