SentinelOne vs Maze Ransomware (protect mode) | Cognizant

On April 17th, it was reported that a large enterprise-class, managed service provider (Cognizant) fell victim to a Maze ransomware attack. This particular campaign includes a signed DLL payload (kepstl32.dll). Upon infection, the trojan will drop a customized desktop image into %temp%, and then traverse the disk, encrypting supported file-types. A copy of the ransom instructions “DECRYPT-FILES.txt” is dropped into each folder containing encrypted files. As with previous variants of Maze, the trojan will attempt to inhibit recovery by deleting shadow copies via WMIC.exe (wmic.exe shadowcopy delete).
