User Execution - Fake Software Crack or Keygen Download
This rule detects attempts by users to download fake software cracks, keygens, activators, patches, or serials from HTTP servers. It specifically looks for HTTP responses containing URIs with keywords like 'crack', 'keygen', 'activator', 'patch', or 'serial' (case-insensitive) and verifies that the downloaded file data starts with 'MZ', indicating a Windows executable. This combination suggests a user is downloading potentially malicious software disguised as a legitimate software cracking tool.
