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
