Summary

IRCBot represents a large family of backdoors - remote access tools. These tools allow for the control of a victims' computers from a remote location by sending specific commands via IRC channels. These backdoors can also steal data and spread to computers vulnerable to exploits.

Removal

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 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.

Technical Details

Upon execution, it creates a copy of itself in the Windows folder and runs from this location:

  • %windir%\system32\wgareg.exe

IRCBot.VY installs itself as a service to ensure that it will run at system startup. The following IRC server and ports are used by the backdoor:

  • 213.230.31.106:36895

A hacker can send commands to the bots on the IRC channel to control the infected computers. Several tasks can be performed, including the following:

  • Scan and spread to computers vulnerable to MS06-040
  • Download and execute additional components
  • Send messages using an IM client
