Mortal Kombat Ransomware Targeting US Victims

This group is clearly financially motivated, using the ransomware as one way to target victims and encrypt files for extortion, in addition to exploiting the chance to steal cryptocurrency. Talos analysts assess that this particular ransomware isn’t very sophisticated as it will target system files and applications too, which are commonly avoided to prevent the system from becoming unstable. A victim will know they are infected because their wallpaper will change to a Mortal Kombat picture which also doubles as the ransom note.
