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.

Technical Details

Trojan:W32/Tinba is usually distributed through malvertising (advertising content that leads the user to sites hosting malicious threats), exploit kits and spam email campaigns. According to news reports, Tinba has been found targeting bank customers in the United States and Europe.

If Tinba successfully infects a device, it can steal banking and personal information through webinjects. To do this, the malware monitors the user's browser activity and if specific banking portals are visited, Tinba injects code to present the victim with fake web forms designed to mimic the legitimate web site. The malware then tricks them into entering their personal information, log-in credentials, etc in the legitimate-looking page.

Tinba may also display socially-engineered messages to lure or pressure the user into entering their information on the fake page; for example, a message may be shown which attempts to convince the victim that funds were accidentally deposited to his account and must be refunded immediately.
