Futs, Trojan.Futs

Summary

Anti-virus software developer Sophos reports the detection of the latest Trojan, Trojan.Futs, that is designed to integrate with Novell Netware. When executed, the Trojan presents the user with a screen containing various options. These include filling the local hard disk, erasing the CMOS memory, deleting all files on the local hard disk, causing the NetWare server to beep constantly, making various NetWare queries or activating a multi-user chat system.

The Trojan includes a "boss screen" option, which pops up a fake Borland Pascal 7.0 window. Troj.Futs also has an option to drop the BW-770-b* DOS executable file virus. *BW-770-b is a DOS executable file virus that when executed, infects COM and EXE files in the current directory, increasing their length by 770 bytes.

Occasionally the virus displays the message: "Don't be a fool, fuck the school", attempts to format the hard drive, or causes the computer to beep constantly until it is rebooted.

The virus was written with the Biological Warfare virus construction kit.

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.
