User Execution - Trojanized Installer Download
This rule detects the download of a potential trojanized installer file over HTTP. It looks for HTTP responses to clients that contain 'setup', 'install', or 'installer' in the URI, have a file size greater than 500KB, and contain the 'MZ' header, indicating a Windows executable. This combination suggests a user is downloading an executable that could be malicious.
