Detects ROOFDECK backdoor persistence via macOS Launch Agents, tightened to require the implant's distinguishing masquerade artifacts (fake Apple-service drop paths, --type=renderer flag, loginwindow.plist impersonation, or the literal 'persist add|remove|check' CLI syntax) rather than generic LaunchAgents plist creation or launchctl load activity, which legitimate macOS software triggers constantly.

Detects indicators of compromise related to the TraderTraitor (KelpDAO) threat actor, including specific file hashes, malicious process paths, C2 network infrastructure (IPs and domains), and malicious TLS certificates. The rule uses filename-path matching to reduce noise from legitimate macOS binaries.

This rule detects scenarios where a device registration event occurs within 15 minutes of a device-code authentication sign-in for the same user. This pattern is indicative of potential account manipulation where an adversary registers their own device to an existing account to maintain persistent access or bypass multi-factor authentication (MFA).
