Note: IRCBot.ST is also known as Mocbot. If you are directed to this description as of August 13, 2006, please also see the description for IRCBot.ST.
Based on the settings of your F-Secure security product, it will either move the file to the quarantine where it cannot spread or cause harm, or remove it.
A False Positive is when a file is incorrectly detected as harmful, usually because its code or behavior resembles known harmful programs. A False Positive will usually be fixed in a subsequent database update without any action needed on your part. If you wish, you may also:
Check for the latest database updates
First check if your F-Secure security program is using the latest detection database updates, then try scanning the file again.
Submit a sample
After checking, if you still believe the file is incorrectly detected, you can submit a sample of it for re-analysis.
NOTE If the file was moved to quarantine, you need to collect the file from quarantine before you can submit it.
Exclude a file from further scanning
If you are certain that the file is safe and want to continue using it, you can exclude it from further scanning by the F-Secure security product.
Note You need administrative rights to change the settings.
The bot's file is a PE executable, 7846 bytes long, packed with MEW file compressor. When the bot's file is started, it copies itself as 'wudpcom.exe' file to Windows System folder and then creates a service with following attributes:
When the bot is active, it connects to an IRC server, joins a particular channel, and acts as a bot there. The following IRC servers are used by the bot:
The bot joins to a password-protected IRC channel where the hacker can send commands to the bots in order to control infected computers. Several tasks can be performed, including the following:
The bot scans for random IP addresses and exploits a vulnerability in the Windows Plug and Play Service (MS05-039). Info on this PnP vulnerability is available here: https://www.microsoft.com/technet/security/Bulletin/MS05-039.mspx
The vulnerability can be exploited via 139/TCP and 445/TCP.
