Hayabusa is a Windows event log fast forensics timeline generator and threat hunting tool. It is multi-threaded for speed and consolidates events from a single host or thousands of systems into one CSV / JSON / JSONL timeline — ready for analysis in LibreOffice, Timeline Explorer, Elastic Stack, Timesketch and more. It can run live on a single system, gather logs for offline analysis, or hunt across the enterprise with Velociraptor.
