Trojan:Android/FakeUpdates, Trojan:Android/FakeUpdates.A


Trojan:Android/FakeUpdates silently forwards details of the device to a remote server, then downloads additional applications to the device's SD card.

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.

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

On installation, Trojan:Android/FakeUpdates forwards details of the compromised device, including its International Mobile Equipment Identity (IMEI) number and its International Mobile Subscriber Identity (IMSI) number, to a remote location.

It then retrieves and decrypts URLs stored in another remote location; these URLs point to the location of a number of applications, which the malware later attempts to download to the 'download' folder on the device's SD card.
