GitHub Stats
About CyLR
CyLR is a live response tool designed for quickly collecting forensic artifacts from hosts during incident response activities. It supports the extraction of key data such as registry hives, event logs, and memory captures, which are vital for triaging security incidents. By automating the collection process, CyLR enables responders to gather evidence efficiently without impacting system performance. Its ease of use and comprehensive artifact collection make it valuable for rapid incident response.
About GRR Rapid Response
GRR Rapid Response is an incident response framework developed at Google, focused on remote live forensics. It consists of a Python agent deployed to target systems and a Python server infrastructure that manages and communicates with agents. GRR enables security teams to collect forensic artifacts at scale across thousands of endpoints without disrupting operations. Analysts can remotely browse filesystems, collect specific files, dump process memory, query the Windows registry, search for IOCs, and execute YARA rules - all from a centralized web console. Its flow-based architecture allows complex investigation workflows to run asynchronously across the fleet. GRR's scalability makes it particularly valuable for large enterprises that need to investigate incidents affecting many machines simultaneously.
