Security researchers from Slovakia-based safety software maker ESET convey discovered a novel Android ransomware that non only encrypts users’ data, but also locks them out of their devices yesteryear changing lock hide PIN.
On exceed of that:
DoubleLocker is the first-ever ransomware to misuse Android accessibility—a characteristic that provides users choice ways to interact alongside their smartphone devices, in addition to mainly misused yesteryear discovered a novel Android ransomware that non only encrypts users’ data, but also locks them out of their devices yesteryear changing lock hide PIN.
On exceed of that:
DoubleLocker is the first-ever ransomware to misuse Android banking Trojans to pocket banking credentials.

After obtaining this accessibility permission, the malware abuses it to gain device's administrator rights in addition to sets itself equally a default habitation application (the launcher)—all without the user's knowledge.
"Setting itself equally a default habitation app – a launcher – is a flim-flam that improves the malware's persistence," explains Štefanko.
"Whenever the user clicks on the habitation button, the ransomware gets activated, in addition to the device gets locked again. Thanks to using the accessibility service, the user does non know that they launch malware yesteryear hitting Home."
Once executed, DoubleLocker offset changes the device PIN to a random value that neither aggressor knows nor stored anywhere in addition to meanwhile the malware encrypts all the files using AES encryption algorithm.
DoubleLocker ransomware demands 0.0130 BTC (approximately USD 74.38 at fourth dimension of writing) in addition to threatens victims to pay the ransom inside 24 hours.
If the ransom is paid, the aggressor provides the decryption primal to unlock the files in addition to remotely resets the PIN to unlock the victim's device.

However, for rooted Android devices alongside debugging means enabled, victims tin move role Android Debug Bridge (ADB) tool to reset PIN without formatting their phones.
