Bitdefender has introduced a free decryption tool (Decryptor) for files that have been encrypted with Fonix and its variants. The tool offers master keys and bare bones decryption with the ability to restore files one by one.
The Fonix malware family, also known as the FonixCrypter or Xinof, was first observed in June 2020 and was active until the end of January 2021. The infected PC system only needs an Internet connection and a locally available cpriv.key file for decryption.
