Automatic action

Once the scan is complete, the F-Secure security product will ask if you want to uninstall the file, move it to the quarantine or keep it installed on your device.

Vulnerability Protection

The vulnerability leveraged by the exploit is application or platform specific; in other words, a specific program (or even a specific version of a particular program) must be installed in order for the exploit to be effective.

To prevent exploitation of such vulnerabilities, please refer to the application or device vendor for the latest updates and additional advice.

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

Exploit:Android/GingerBreak is a rooting exploit that can be used on Android 2.3.3 (Gingerbread) devices to escalate privileges on the system. Based on the author's own description of the exploit and examination of its binary, it may also work on Android 2.2 (Froyo) and 3.0 (Honeycomb) devices. This exploit may be willingly used by the device's own user to gain root privileges on the device; or silently used by an attacker to gain unauthorized access to the device.

GingerBreak is known to have first been used in Trojan:Android/GinMaster (also known as GingerMaster).

The vulnerability targeted by the GingerBreak exploit was patched in the 2.3.4 update for the Android operating system.
