This rule detects the DarkSide ransomware by identifying specific byte patterns (YARA signatures) associated with its functionality. The rule looks for combinations of code that suggest file enumeration, drive enumeration, privilege escalation, and network share enumeration, which are common behaviors of DarkSide ransomware. Specifically, it checks for two main sets of conditions: one involving finding files, enumerating drives, and escalating privileges, and another involving finding files and enumerating network shares. The rule also verifies that the file is a Windows executable (MZ header).
