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.

Technical Details

Spyware:SymbOS/Mopofeli.A is an SMS spy tool that runs on Symbian Series 60 Second Edition devices.

Installation

When Mopofeli.A is installed, the installer saves its files to the device's C:/ drive.

It then removes its uninstallation information from the install logs and hide its process from the application process list.

Mopofeli.A does not have any kind of user interface or uninstallation option; the only way to detect its presence is to use an antivirus program or a third party file manager that shows the contents of the System\apps directory.

Activity

When active on the device, Mopofeli.A hides its process so that it is not visible in the Symbian process list. Also, it does not have an application icon and entry in the application uninstallation list.

The only way for a victim to detect Mopofeli.A is to locate the application files in file system or to use an antivirus application.

Propagation

Mopofeli.A monitors the user's incoming and outgoing SMS traffic, and as soon as the user sends or receives an SMS message, Mopofeli.A will forward this to the number that is configured in the software license. Mopofeli.A thus makes it possible for the individual that installs it to monitor all SMS traffic that the victim sends or receives on the target phone.

To prevent the user from noticing the extra messages, Mopofeli.A will remove the message from the Sent SMS messages list.
