Ransomware Encrypted Files – by DoubleLocker on Android

ESET North America security researchers have identified a new ransomware on Android operating system. They have named this ransomware encrypted files DoubleLocker. This wicked ransomware not only encrypts all your data on your Android device, but also locks your device.

This ransomware misuses Android accessibility services via a banking trojan. However, DoubleLocker does not obtain your banking credentials and stealing your money. Instead this ransomware encrypts your device data, locks your device, and then requests a ransom payment.

This ransomware also has the ability to change your Personal Identification Number, locking you out of your device.

“Given its banking malware roots, DoubleLocker may well be turned into what could be called ransom-bankers. Two-stage malware that first tries to wipe your bank or PayPal account and subsequently locks your device and data to request a ransom… Speculation aside, we spotted a test version of such a ransom-banker in the wild as long ago as May, 2017,”
