FireEye Mandiant SunBurst Countermeasures
Security teams hunting for supply chain compromise indicators will find immediate value in FireEye Mandiant SunBurst Countermeasures because the rules are written by the analysts who actually reverse-engineered the attack, not guesses from a detection lab. The 560 GitHub stars reflect real adoption among threat hunters validating these signatures against their own telemetry. Skip this if you need a polished GUI or automated response workflows; this is raw detection logic for teams comfortable reading YARA rules and building their own operationalization layer.
Threat hunters and incident responders who need production-ready detection logic tied to real Trellix ATR investigations should use Yara-Rules Repository.
