Re: KIT.GED

[GuidoZ <uberguidoz () gmail com>]

Hello Raoul!

It might of been due to something ELSE running on your server. What
other services/ports are open? (SSH, Telnet, SMTP, VNC, etc) It's
possible another protocol or service was exploited, allowing access.
(Then might of just upped the kit for later retrieval from a malware
infection or something.)

Leaving it up there, then monitoring the traffic to it could prove to
be useful. I'd also highly advise looking through log files and the
event viewer for anything out of the ordinary, or related whatsoever.
Judging from the files contained in the kit, it looks like they were
preparing to cover their tracks if necessary.

If you'd like to send a copy of it my way, I'd be happy to peek at it
and see if anything else becomes obvious. You may send it to my virus
catch all - guidoz _AT guidoz _DOT_ com (Make the subject meaningful,
like "Rootkit from FD as requested" or something. Otherwise I'll skip
right over it thinking it's spam.) Will email you directly with any
results.
