However, researchers now imagine that as of May 2020, the group has resumed assaults as soon as once more, with the WastedLocker malware as its newest creation. The malware has been named “WastedLocker” as a result of filename created by the malware, which provides an abbreviation of the sufferer’s identify to the phrase “wasted.”

It may however be less obvious when they hit a personal device that an employee is using while working remotely, and which is only connected to corporate resources on an intermittent basis.”
