Name: W32/Codbot-Gen
Type: Win32 worm
Date: 5 April 2005
A virus identity (IDE) file which provides protection is
available now from the Sophos website, and will be incorporated
into the May 2005 (3.93) release of Sophos Anti-Virus.
Customers using EM Library, PureMessage or any of our Sophos
small business solutions will be automatically protected at
their next scheduled update.
At the time of writing, Sophos has received a small number of
reports of this worm from the wild.
Note: Sophos has updated this IDE to improve detection of the
Troj/Borobt family of Trojans
Information about W32/Codbot-Gen can be found at:

Sophos Anti-Virus products detect members of the W32/Codbot family of worms as
W32/Codbot-Gen.
Worms detected as W32/Codbot-Gen provide backdoor Trojan functionality to a
remote attacker via IRC channels. Such worms may spread to remote network
shares with weak passwords in response to a command from a remote attacker.
Members of W32/Codbot family may copy themselves to the Windows system folder
and create entries in the following registry entries to run themselves when the
user logs on:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices
HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Minimal
This backdoor functionality typically includes the ability to sniff packets,
download further malicious code and steal passwords and other system
information.
W32/Codbot worms may register themselves as service processes.
Members of W32/Codbot family typically attempt to exploit vulnerabilities, such
as the LSASS vulnerability (MS04-011).
This IDE file also includes detection for:
Troj/Borobt-Gen

Download all the IDE files available for the current version of
Sophos Anti-Virus in a single compressed file. The file is
