Name: W32/Codbot-Gen
Type: Win32 worm
Date: 30 June 2005
Sophos has issued protection for W32/Codbot-Gen.
At the time of writing, Sophos has received a small number of
reports of this worm from the wild.
Customers using EM Library, Enterprise Console, PureMessage or
any of our Sophos small business solutions will be automatically
protected at their next scheduled update.
Note: Sophos has updated this IDE to improve detection of the
W32/Codbot family of worms

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).
The W32/Codbot-Gen virus identity file (IDE) includes detection for:
Troj/Borobt-Gen
