FilesLocker is a new ransomware-as-a-service (RaaS) that targets Chinese and English speaking users. The creators of FilesLocker are offering the malware to other attackers for distribution in return for a share of the ransom payments.
FilesLocker encrypts files using the RSA 2048+AES algorithm and then appends the .locked extension to encrypted files. It will then display a ransom screen that cannot be closed. Ransom notes in Chinese and English are created in various folders throughout the computer.
When encrypting a victim’s files, it targets specific folders such as the Desktop, Documents, Music, Pictures, etc and appends the .locked extension to encrypted files.
