BNFD Ransomware
The BNFD Ransomware is the name given to a new Matrix variant that has been detected in the wild. As such, it doesn't show many differences from the typical Matrix functionality. BNFD uses an uncrackable combination of two cryptographic algorithms - AES-256 and RSA-2048 to lock the user's files effectively. The encrypted data cannot be accessed and cannot be used in any way. The name of the files affected by the threat will be changed completely. The BNFD Ransomware substitutes the original filenames with ones consisting of an email address under the control of the hackers, a 17-character string of random characters and finally '.BNFD' as a new file extension. The email address it uses is 'Benford333@criptext.com.' The ransom note is delivered in the form of 'BNFD_README.rtf' files created in every folder containing encrypted files.
The note provides two additional email addresses for contact - 'Benford333@protonmail.com' and 'Benford333@tutanota.com.' The victims of the BNFD Ransomware are told to send a message to all three addresses explicitly. They also can attach up to three non-important files to be decrypted for free. The subject of the emails should be the specific ID that can be found in the ransom message. The note doesn't have any details about the amount of money that the criminals will demand.
The full text of the ransom note of the BNFD Ransomware is:
