GRR Rapid Response is an incident response framework focused on remote live forensics.
The goal of GRR is to support forensics and investigations in a fast, scalable manner to allow analysts to quickly triage attacks and perform analysis remotely.
GRR consists of 2 parts: client and server.
GRR client is deployed on systems that one might want to investigate. On every such system, once deployed, GRR client periodically polls GRR frontend servers for work. “Work” means running a specific action: downloading file, listing a directory, etc.
GRR server infrastructure consists of several components (frontends, workers, UI servers) and provides web-based graphical user interface and an API endpoint that allows analysts to schedule actions on clients and view and process collected data.
Key Features
- Client:
- Live remote memory analysis using YARA library.
- Powerful search and download capabilities for files and the Windows registry.
- OS-level and raw file system access, using the SleuthKit (TSK).
- Secure communication infrastructure designed for Internet deployment.
- Detailed monitoring of client CPU, memory, IO usage and self-imposed limits.
- Cross-platform support for Linux, OS X and Windows clients.
- Server:
- Fully fledged response capabilities handling most incident response and forensics tasks.
- Enterprise hunting (searching across a fleet of machines) support.
- Fast and simple collection of hundreds of digital forensic artifacts.
- AngularJS Web UI and RESTful JSON API with client libraries in Python, PowerShell and Go.
- Powerful data export features supporting variety of formats and output plugins.
- Fully scalable back-end capable of handling large deployments.
- Automated scheduling for recurring tasks.
- Asynchronous design allowing future task scheduling for clients, designed to work with a large fleet of laptops.
