      Ransomware often targets backup files to inhibit system recovery.

    • Modifies boot configuration data using bcdedit

    • Renames multiple (7585) files with added filename extension

      This suggests ransomware activity of encrypting all the files on the system.

    • Deletes System State backups

      Uses wbadmin.exe to inhibit system recovery.

    • Enumerates connected drives

      Attempts to read the root path of hard drives other than the default C: drive.
