Trojan:Android/NewBak.A usurps the name and appearance of a legitimate mobile banking application. When users enter banking details into the app, the information is silently recorded and forwarded to a remote server.
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.
Trojan:Android/NewBak.A steals the name, app icon and appearance of the legitimate My One Wallet mobile banking application. If the user enters their bank card details into the trojan's interface and presses OK, the app takes a screenshot of the submitted data and sends it to a remote server (most likely the trojan's Command and Control server).
The trojan also downloads another file from the same server onto the device.
Newbak.A imitates an app that is intended for use by South Korean mobile banking users, so it's likely this trojan targets mainly Korean or Korean-speaking users.
