GRR Rapid Response is a Python-based incident response framework developed by Google that enables remote live forensics at scale. The system consists of a client agent deployed on target systems and server infrastructure for centralized management. GRR supports cross-platform deployments (Linux, macOS, Windows) and provides capabilities for live remote memory analysis using YARA, powerful file and registry search/download, OS-level and raw filesystem access via SleuthKit, and enterprise hunting across large fleets of machines. The platform features secure communication infrastructure designed for internet deployment, detailed resource monitoring with self-imposed limits, automatic client updates, and fully scalable backend architecture. GRR excels in scenarios like remote machine investigation, forensic acquisition of multiple systems across continents, compromise assessment at scale, and fleet-wide threat hunting. It integrates with Google Security Operations (SecOps) and supports automated scheduling with comprehensive API access.
