This PR introduces a couple of update and fixes:

  • Cobalt Strike Named Pipes - Added additional named pipes
  • Detect Renamed WinRAR - Fixed issue in logic as reported in [BUG] Logical flaw in ESCU rule "Detect Renamed WinRAR" due to incorrect use of OR instead of AND in process #3550
  • Icacls Deny Command - Enhanced the logic by adding additional options
  • ICACLS Grant Command - Enhanced the logic by adding additional options
  • Modify ACL permission To Files Or Folder - Enhanced the logic by adding additional options
  • Suspicious Copy on System32 - Reworked the logic to avoid FPs and FNs. Namely the previous logic did not take into account xcopy (and its sisters) starting from a full path (AKA containing System32 or SysWOW64). It also incorrectly split the CommandLine on a space character which introduces inconsistency in the logic
