Description
W32/Mytob-BS is a mass-mailing worm and IRC backdoor Trojan for the
Windows platform.
W32/Mytob-BS spreads to other network computers by exploiting common
buffer overflow vulnerabilites, including: RPC-DCOM (MS04-012) and LSASS
(MS04-011) and by copying itself to network shares protected by weak
passwords.
W32/Mytob-BS runs continuously in the background, providing a backdoor
server which allows a remote intruder to gain access and control over
the computer via IRC channels.
W32/Mytob-BS is capable of spreading through email. Email sent by
W32/Mytob-BS has the following properties:
Subject line chosen from:
Good day
hello
Mail Delivery System

Message text chosen from:
'Mail transaction failed. Partial message is available.'
'The message contains Unicode characters and has been sent as a binary

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.
The following patches for the operating system vulnerabilities exploited
by W32/Mytob-BS can be obtained from the Microsoft website:

W32/Mytob-BS is a mass-mailing worm and IRC backdoor Trojan for the
Windows platform.
W32/Mytob-BS spreads to other network computers by exploiting common
buffer overflow vulnerabilites, including: RPC-DCOM (MS04-012) and LSASS
(MS04-011) and by copying itself to network shares protected by weak
passwords.
W32/Mytob-BS runs continuously in the background, providing a backdoor
server which allows a remote intruder to gain access and control over
the computer via IRC channels.
When first run W32/Mytob-BS copies itself to <System>\logitechwls.exe
and creates the following registry entries:
HKCU\SYSTEM\CurrentControlSet\Control\Lsa
Logitech Wireless
logitechwls.exe
HKCU\Software\Microsoft\OLE
Logitech Wireless
logitechwls.exe
HKCU\Software\Microsoft\Windows\CurrentVersion\Run
Logitech Wireless
logitechwls.exe
HKLM\SOFTWARE\Microsoft\Ole
Logitech Wireless
logitechwls.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
Logitech Wireless
logitechwls.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
Logitech Wireless
logitechwls.exe
HKLM\SYSTEM\CurrentControlSet\Control\Lsa
Logitech Wireless
logitechwls.exe
W32/Mytob-BS copies itself to the root folder as:
funny_pic.scr
my_photo2005.scr
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 files through Windows Messenger to all online contacts.
W32/Mytob-BS injects itself into the Windows Explorer process to stealth
itself.
W32/Mytob-BS also includes functionality to spawn a remote command shell
and also silently download, install and run new software.
W32/Mytob-BS modifies the HOSTS file, changing the URL-to-IP mappings
for selected websites, therefore preventing normal access to these sites.
The new HOSTS file will typically contain the following:
127.0.0.1 www.symantec.com
