RE: new trojan

[Stephen Blass <Stephen.Blass () asu edu>]

We've been fighting with a trojan named wms.exe for a while now and this is the first I've heard of an AV product 
catching it.  That's good news.  The version I've found pulls ServU-FTP along with it and sets it self up as a service 
named WinIP.  The one we have been wrestling with uses a svcinst.exe to process a rtl386.sys containing instructions to 
install as the service WinIP "IP Helper API" and then connect outbound to
irc.elite-irc.net  6667
crystal.elite-irc.net 7000
darwin.elite-irc.net 6667
killer.elite-irc.net 6667
It also tries to connect outbound to fuel.pyroshells.com, dnsix.com and 192.168.0.1.
It comes with MySQLdb.dll and appears to report the IP address(es) of the compromised host(s) back to some central 
database. There's even a credits line that reads iSoZoNE WAS H3R3.  It installs files named 1MB.Test and 5MB.Test in 
%sysdir%\pk32 and sets up an admin password entry.  The pk32 directory is setup as home in the ServuDaemon config file.

To clean it out - we remove the WMS.exe from %sysdir% (we've seen it on win2k and XP) and remove the install kit from 
%sysdir%\system32\nt, the Servu* files and Serv-UID from %sysdir%, and delete the %sysdir%\pk32 directory.  On the 
compromised machines we have found you can see WMS.exe in the task manager process list and the WinIP service in the 
services list. I've not seen the BUNDLER_WMS.EXE filename yet so maybe you have something different or perhaps this is 
evolution.

Has anyone seen or know of the Win32/Toolber.c.Trojan, what it does. My av
found it in     \WINNT\BUNDLER_WMS.EXE.  I searched TrendMicro,Sophos,CA,
Symantic, Mcafee and could not find a reference.
