RE: Logon.dll? Possible root-kit?

[Jason Pagano <JPAGANO () orthonet-online com>]

Logon.dll and dir.dll are just serv-u's motd/dir change files..
MsCtrl32ocx.ocx is the conf (open it in wordpad)
Su.exe and explorer.exe are both serv-u (rooted by 2 different people?).. 
All the DWRC* and DNTUS26.exe is dameware (dameware.com)
The batch files were probably run as services
I'd be willing to bet the ranch that the hacked box had a null or weak admin
pass... probably on a fast line aswell seeing it was being used as a pub
warez box .. look in c:\winnt\system32\spool\drivers\color\
You'll find your warez there
Bot.dll is packed with upx, after decompressing it and takin a look there is
atleast 3 references to 3 different ircd's .. and version reply

Ok here is link to a rar of the suspected files:
    http://www.ethicsdesign.com/HackLog.rar

As some of you said, it looks like there is not a rootkit installed, and it
looks like this was an attempt at making this box join a botnet.  A kindly
IRCOp has offered to both decompile the bot dll, and to remove the offending
channel (#thallia), so that is taken care of.  Anyway, I did manage to
convince my clients that this was serious enough to warant a wipe of the
data on the machine.  I am waiting to see what your analysis of these files
are.

Thank You,
Nick Jacobsen
