see_this!!.scr
and drops a file called hellmsn.exe (detected by Sophos as W32/Mytob-D)
in the same location. This component attempts to spread the worm by
sending the aforementioned SCR files through Windows Messenger to all
online contacts.
W32/Mytob-BZ also appends the following to the HOSTS file to deny
access to security related websites:

been sent as a binary attachment.'
'The original message was included as an attachment.'
'Here are your banks documents.'
The attached file consists of a base name followed by the extentions
PIF, SCR, EXE or ZIP. The worm may optionally create double
extensions where the first extension is DOC, TXT or HTM and the final
extension is PIF, SCR, EXE or ZIP.

Type
* Worm
Aliases
* WORM_RANDEX.GEN
* Backdoor.IRCBot.gen
Prevalence (1-5) 2
Description
W32/Randex-Y is a network worm with backdoor capabilities which
allows a remote intruder to access and control the computer via IRC
channels.
W32/Randex-Y chooses IP addresses at random and tries to connect to
the IPC$ share using simple passwords. If the connection is
successful the worm copies itself to the following remote locations:
\ADMIN$\system32\msnv32.exe
\C$\WINNT\system32\msnv32.exe
W32/Randex-Y then schedules a job to execute the remotely created
files.
Each time the worm is run it tries to connect to a remote IRC server
and join a specific channel. The worm then runs in the background as
a server process listening for commands to execute.
When first run the worm copies itself to the Windows system folder as
IRBMe.exe and adds the following registry entries to point to this
copy of the worm to ensure it is run at system startup:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\IRBMe Sucks!!
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices\IRBMe Sucks!!
W32/Randex-Y may also create the file remove.bat in the Windows temp
folder. This file is not malicious and can simply be deleted.
