More Information
W32/Forbot-FE is a IRC backdoor Trojan and network worm for the Windows platform.
W32/Forbot-FE connects to a preconfigured IRC server and joins a channel from which an attacker can issue further commands. These commands can cause the infected computer to perform any of the following actions:
flood a remote host (by either ping or HTTP)
start a SOCKS4 proxy server
start an HTTP server
start an FTP server
portscan randomly-chosen IP addresses
execute arbitrary commands
steal information such as passwords and product keys
upload/download files
In order to run automatically when Windows starts up the worm moves itself to the Windows system folder as Messenger.exe and creates the following registry entries:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
Yahoo Updater
Messenger.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce
Yahoo Updater
Messenger.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
Yahoo Updater
Messenger.exe
HKCU\Software\Microsoft\Windows\CurrentVersion\Run
Yahoo Updater
Messenger.exe
HKCU\Software\Microsoft\Windows\CurrentVersion\RunOnce
Yahoo Updater
Messenger.exe
W32/Forbot-FE also creates its own service named "Updater", with the display name "Yahoo Updater".
Several registry entries will be created under the following entry:
HKLM\SYSTEM\CurrentControlSet\Services\Updater
