Pre-Installed Android Malware Found On 36 High-end Smartphones
The malicious apps were not part of the official ROM supplied by the vendor, and were added somewhere along the supply chain. Six of the malware instances were added by a malicious actor to the device’s ROM using system privileges, meaning they couldn’t be removed by the user and the device had to be re-flashed.
Most of the malware found to be pre-installed on the devices were info-stealers and rough ad networks, and one of them was Slocker, a mobile ransomware. Slocker uses the AES encryption algorithm to encrypt all files on the device and demand ransom in return for their decryption key. Slocker uses Tor for its C&C communications.
