Removal

Based on the settings of your F-Secure security product, it may block the file from running, move it to the quarantine where it cannot spread or cause harm, or ask you to select an action.

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

Installation and Activation

Installation of FlexiSPY requires physical access to the monitored phone. It is commerical software and uses a unique activation key. The key is tied to a user account on the backend server through which the monitored activity can be reviewed via a website interface.

Once Flexispy is on the device, the phone is rebooted to allow the software to hook into various locations of the phone's operating system. This is required in order to collect information about the phone's usage.

Hidden Interface

FlexiSPY uses a hidden interface. A passcode is required to access the control panel.

Once activated, the passcode is changed from the default of *#900900900 to the unique activation key.

RBackup.exe

The file responsible for the configuration pane is RBackup.exe, which is stored in the \Windows\VPhone folder.

Once the settings are configured, and the user selects apply, the details are saved into an "encrypted" setting file also stored in the \Windows\VPhone folder.

Collected information is also stored, in the same directory, inside the files 1.sys (e-mail), 2.sys (phone calls), and 3.sys (text messages). These files are not encrypted which means they can be opened in any text editor for review.

Upon reboot and a successful configuration, the three new services on the Windows Mobile device start recording and managing communications. In summary, FPMapi.dll monitors the incoming e-mails and text messages, VRILLibCM.dll is responsible for cell tower tracking, and VPhone.dll is responsible for everything else.

Because these three files are started as a service, they are difficult for the average user to detect, which means the program and its operations are likely to go unnoticed by the average Windows Mobile user.
