What is Mr-X666 ransomware? And how does it carry out its attack?

Mr-X666 ransomware is yet another file-encrypting virus that was discovered in March 2019.

Once all these changes are applied, it scans the computer for files with certain extensions like .jpeg, .mp4, .docx or .doc, .mp4 or .avi, .mp3 and many more.
