Detects potential web shell installation via WordPress administrative panels. The rule identifies a WordPress administrator session executing a theme installation request triggered by an external (off-site) referer, followed shortly thereafter by the creation of new PHP files within the WordPress themes directory. This pattern is often indicative of an attacker leveraging a compromised admin session to upload a backdoor.

Detects instances of ImageMagick binaries (convert, identify, magick) spawning suspicious child processes (e.g., shells, network tools, scripting interpreters) when processing image files with HEIF/HEIC extensions. This is a common pattern for exploiting image processing vulnerabilities (e.g., ImageTragick) to achieve remote code execution.

Detects pull requests created in GitHub repositories by entities labeled as 'Bot', 'App', or 'integration', or containing the term 'codex', specifically targeting repositories where such entities have not performed these actions in the previous 30 days. This baseline approach identifies potentially hijacked or unauthorized automation accounts performing activities outside of their standard repository scope.

Detects instances where a user grants OAuth application permissions to GitHub or Slack shortly (within 30 minutes) after signing into a low-trust application (Discourse or OpenAI Community), suggesting a potential session hijacking or trusted-relationship abuse scenario where an attacker leverages an existing SSO session to authorize malicious applications.
