Wontok Lab Results
We observed that Wontok SafeCentral Mobile Security’s On-access and On-demand engines properly detect Android.Slocker.FE and remediate the malware, which prevents the ransomware from delivering its payload and infecting the device.
Android.Slocker ransomware was observed initially by displaying a fake FBI warning stating suspicious files had been found on the device, at the same time the smartphone’s “home” and “back” buttons were disabled. Once encryption has occurred scammers demand a $500-$1500 ransom be paid via BitCoin, PayPal or other services in order for the AES decrypting to occur.
This ransomware communicates through ‘The Onion Router’ (TOR) network to the ‘Command and Control’ (C&C) servers that issue its commands. With the ability to collect sensitive information such as its IMEI (International Mobile Equipment Identity) number and return the information to the C&C server.
Older versions of Slocker receive commands through SMS messages. With commands observed to be originating from phone numbers traced to the Ukraine and Russia.
