The operators of the REvil Ransomware, otherwise known as Sodinokibi, have announced that they will use stolen files and data as leverage to get victims to pay ransoms. A new tactic by ransomware developers is to release a victim’s data if they do not pay the ransom. While we have seen these threats in the past, only recently have Ransomware operators, such as Maze, actually followed through.
