Summary

This type of trojan secretly downloads malicious files from a remote server, then installs and executes the files.

Removal

Automatic action

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.

Suspect a file is incorrectly detected (a False Positive)?

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.

To distract the user from detecting any malicious activity, the trojan also download innocuous-looking files from:

  • http://www.paeksan.com/technote/001.jpg
  • http://www.paeksan.com/technote/002.jpg

The first JPEG file, 001.jpg, will be renamed tomsnmsgsr.exe;the second JPEG file, 002.jpg, will be renamed toinnit226.exe. Both are renamed using Windows command prompt and stored on %windir%\system32. As these files share similar names with the malicious binary files, they help camouflage the trojan's activity.Upon successful execution of the trojan, Internet Explorer will open the page http://www.orkut.com, a social networking site.This trojan was written in Borland Delphi.
