RAR Archive Creation with Password or Specific Compression Level
This rule detects the execution of the 'rar.exe' utility with command-line arguments indicating the creation of an archive that is either password-protected ('-hp') or uses a specific compression level ('-m'). This combination of parameters is often associated with malicious activities, such as data exfiltration or staging, where adversaries compress and password-protect data before moving it off a compromised system.
