Unreal IRC Server files gets replaced with ones containing backdoor

Forum post @ Unreal IRCD

We found out that the Unreal3.2.8.1.tar.gz file on our mirrors has been replaced quite a while ago with a version with a backdoor (trojan) in it.

This backdoor allows a person to execute ANY command with the privileges of the user running the ircd. The backdoor can be executed regardless of any user

restrictions (so even if you have passworded server or hub that doesn't allow any users in).

It appears the replacement of the .tar.gz occurred in November 2009 (at least on some mirrors). It seems nobody noticed it until now.

Not good.
