RE: Name that Trojan

Backnote 
This trojan is your average password stealing trojan that tries to send
passwords it collects to a hotmail account . There are two variants of
the backdoor. They have been circulated in e-mail and newsgroups
postings as attachment files called PICTURE.EXE and MANAGER.EXE, sized
353792 bytes and 348672 bytes. Both of them copy themselves to the
Windows directory as a file called NOTE.EXE file name and register
themselves to be executed every time Windows boots up.

After this, the trojan gathers information from the machine, including
username and password, copies them to an encrypted DAT file and tries to
e-mail that file to addresses abreb () hotmail com and chinafax () 263 net.
This trojan does not spread by itself. It can be removed simply by
deleting the NOTE.EXE file and the original carrier file. It is
recommended that you change your password if you believe to be affected
by this trojan. 
    
 A-trojan
This trojan is in some weird language that I don't understand but from
what I can gather it can do quite a few things . The server opened port
170 tcp on my computer but it is probably configurable . 

Removal : 
Go to start and then to run and type regedit . 
When regedit opens you will need to follow the following path 
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
Once you have done that , look for the word Rundll16 , delete this
registry key . 
Reboot . 
Now go to start , then to find and look for rundll16.exe , when you find
it right click on the file and choose delete . Now go to windows system
directory and delete the following files : MdiHole.exe, MsDecay.scr,
Msvsrv.exe and watching.dll
Reboot , and your pc should be clean

Subject: Name that Trojan


We have an application server running NT 4.0.  We found the file
serv.exe on
it and I know that this could be an indication of a Trojan.  We deleteed
the
file and when we rebooted, the file re-appeared.  I trying to find out
if
anybody know what Trojan might display this activity?  I thaught it was
freak but that seemed old and I didn''t think that it could regenerate
the
.exe  Any Answers?

Cheers,
Eric
