Two new Matrix Ransomware variants were discovered this week by MalwareHunterTeam that are being installed through hacked Remote Desktop services. While both of these variants encrypt your computer’s files, one is a bit more advanced with more debugging messages and the use of cipher to wipe free space. Both variants encrypt unmapped network shares, display status windows while encrypting, clear shadow volume copies, and encrypt the filenames. Unfortunately, this one cannot be decrypted for free, like the previous one.
