Stokx.A is a harmful program that connects to a remote server, forwards the device information to the server, and sends out SMS messages to a specified number.
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.
Stokx.A connects to a remote server and receives an XML file. The file contains details such as client ID, phone number that it will send SMS messages to, and URL for downloading additional APKs.
The malware will forward the device's International Mobile Equipment Identity (IMEI) number to the remote server, and sends out an SMS message with the content "SX357242043237517" to the number 13810845191.
