Analysis Summary
Rhino Ransomware is one of the latest in ransomware analyzed by researchers. The ransomware carries several capabilities including, disabling services, hindering backup recovery, deleting shadow copies, and persistence. The first step of infection disables several Windows Security and Defender services, as well as Windows Update service, and error reporting. Additionally, the ransomware attempts to stop Microsoft Exchange, sqlserver, and sqlwriter. Stopping these services leads the researchers to believe the targeted victims could be businesses. The next step is the deleting of shadow copies and the backup catalog, as well as Windows Recovery Mode. Persistence is achieved through a registry entry and copying itself to the %AppData% directory as mshtop32bit.exe. After file encryption, a file marker “Marvel01 is added. An email address is included in the ransom email note. Excluded file types are .EXE, .SYS, .LNK, .DLL, .MSI, and the ransomware’s notes.
