If you can keep your head when all about you
Are losing theirs and blaming it on you;
If you can trust yourself when all men doubt you,
But make allowance for their doubting too;
If you can wait and not be tired by waiting,
Or, being lied about,don't deal in lies,
Or, being hated, don't give way to hating,
And yet don't look too good, nor talk too wise;

The worm looks for shared KaZaA directory with a registry entry and copies itself in it as:
wrar320sc
REALONE
BlackIcePCPSetup_creak
Passware5.3
word_pass_creak
HEROSOFT
orcard_original_creak
rainbowcrack-1.1-win
W32Dasm
setup
%random file name%

with the extension:
.bat
.exe
.pif
.scr

It copies itself in all shared network directories as one of the following:
CD-Cover Editor 2.6.exe
Zealot All Video Splitter 1.1.9.zip.exe
Backup Made Simple 5.1.58 crack.exe
Zealot.exe

It uses the following passwords, for accessing local networks of other computers and for logging as administrator:

If access succeeds, the worm copies itself as:
\\%network Computername%\admin$\systemdir\NetManager32.exe and opens the file "Management Service Extension".

Technical DetailsWhen activated, Worm/Lovgate.T is copied as read-only, hidden, system files:
%WinDIR%\Systra.exe
%SystemDIR%\iexplore.exe
%SystemDIR%\Media32.exe
%SystemDIR%\RAVMOND.exe
%SystemDIR%\WinHelp.exe
%SystemDIR%\Kernel66.dll,

It creates AUTORUN.INF in start directory on all drives, except for the CD-ROM drive and copies itself as COMMAND.EXE in these directories.

Then, it creates a .zip file (%filename%.%ext%) in start directory of all drives, except for drives A: and B:. The %filename% can be:
WORK
setup
Important
bak
letter
pass

and the %ext%:
RAR
ZIP

This .zip file contains a worm copy, that can have the following names:
WORK
setup
Important
book
email
PassWord

and extension:
exe
com
pif
scr

Then, it creates the following files:
%System%\ODBC16.dll (53,760 Bytes)
%System%\msjdbc11.dll (53,760 Bytes)
%System%\MSSIGN30.DLL (53,760 Bytes)

These are all backdoor components of the worm.
It changes the registry entry:
HKEY_CLASSES_ROOT\exefile\shell\open\command
into: %SystemDIR%\Media32.exe "%1" %*
Thus, the worm is activated every time an .exe file is opened.

It also terminates all processes containing the following strings:
KV
KAV
Duba
NAV
kill
RavMon.exe
Rfw.exe
Gate
McAfee
Symantec
SkyNet
rising

It makes the following registry entries:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run "Program in Windows"="%SystemDIR%\iexplore.exe""VFW Encoder/Decoder Settings"="RUNDLL32.exe MSSIGN30.DLL ondll_reg""WinHelp"="%SystemDIR%\WinHelp.exe" HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows "run"="RAVMOND.exe" (for autostart). HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunServices "Systemtra"="%WinDIR%\Systra.exe" (for autostart, as service.)
Eventually, the following entry is made:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\ZMXLIB1

Then it performs a backdoor routine on port 6000. The routine steals information from a compressed system and saves it in C:\Netlog.txt. Then, the worm sends this information to an email address.

Kurzfassung hier.
