Trojan:Android/Kmin, Trojan:Android/Kmin.A, Trojan:Android/Kmin.B, Trojan:Android/Kmin.C


Trojan:Android/Kmin variants display a message as a decoy, while silently performing multiple malicious routines, including sending SMS messages to a premium-rate number and downloading and installing an additional application onto the device.


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.

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

Upon execution, variants in the Kmin trojan family display a message asking the user for a permission to proceed with a specified action; the A variant asks whether the user wishes to install a paid app and subscribe to a service, while the B and C variants only enquire whether the user would like to install a paid application.

Regardless of whether the user accepts or declines, the app will proceed with the following actions:

  • Sending the Internation Mobile Equipment Identity (IMEI) number and phone number to a remote server
  • Sending SMS messages to a premium-rate number
  • Downloading and installing another application
  • Running services in the background


  • Trojan:Android/Kmin.A
  • Trojan:Android/Kmin.B
  • Trojan:Android/Kmin.C
