You've likely heard this one already, but here it is again: over the weekend, the UnrealIRCd team discovered 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." Yeek. This, obviously, is not great news, because according to the team, apparently this switcheroo has gone unnoticed on some of Unreal's mirror sites since as early as November 2009.
