Name: W32/Agobot-HD
Type: Win32 worm
Date: 27 April 2004

A virus identity (IDE) file which provides protection is
available now from the Sophos website, and will be incorporated
into the June 2004 (3.82) release of Sophos Anti-Virus.

Customers using Enterprise Manager, PureMessage and any 
of the Sophos small business solutions will be automatically
protected at their next scheduled update.


At the time of writing, Sophos has received just one report of
this worm from the wild.


Information about W32/Agobot-HD can be found at:
http://www.sophos.com/virusinfo/analyses/w32agobothd.html
Description 
W32/Agobot-HD is an IRC backdoor Trojan and network worm. 
W32/Agobot-HD is capable of spreading to computers on the local network
protected by weak passwords. 

When first run W32/Agobot-HD copies itself to the Windows system folder as
wmiprvsw.exe and creates the following registry entries to run itself on
startup: 

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
System Updater Service = wmiprvsw.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
System Updater Service = wmiprvsw.exe 

Each time W32/Agobot-HD is run it attempts to connect to a remote IRC server
and join a specific channel. 

W32/Agobot-HD then runs continuously in the background, allowing a remote
intruder to access and control the computer via IRC channels. 

W32/Agobot-HD attempts to terminate and disable various anti-virus and
security-related programs. 

W32/Agobot-HD includes a stealthing component which attempts to hide the
worm.
