A new ransomware attacks and blocks Android, its name is DoubleLocker. Its name is due to the fact that it blocks the Google home mobile operating system twice!
Like most Android ransomware, it encrypts files in the internal memory. But it also changes the PIN.
DoubleLocker looks like a normal Adobe Flash update. As soon as its code is executed, it asks for access to accessibility features and uses administrator rights to replace the launcher on the Android device.
After that, the first time the user clicks the home button, the DoubleLocker ransomware encrypts all files using the AES encryption algorithm and changes the PIN causally.
Lastly, it asks the user to pay 0,013 Bitcoins (about $ 60) to retrieve the file decoding key.
If the payment is not made within 24 hours, the decoding key and the PIN are deleted and the files are lost forever.
In practice, this is another threat to anyone who owns an Android device. So, our recommendation is to always be careful and eliminate all those behaviors commonly considered dangerous.
