What is RedRum Ransomware

RedRum Ransomware is a malicious piece that encrypts your data and demands to pay a ransom. Once the penetration reaches success, all stored data including images, videos, and text files will be encrypted with .redrum or .grinch (another version of RedRum family) extension. Case in point, if 1.mp4 got attacked by this virus, it will transform itself into 1.mp4.redrum or 1.mp4.grinch. As soon as encryption completes, RedRum will drop a text file (decryption.txt) with ransom information.
