Hayabusa¶
What Hayabusa does¶
Guided SUSA tool journey
Hayabusa supports event-log analysis. In this guide, you will use it to create a filtered event timeline and explain one high-value sequence. The procedure and screenshots provide the practical reference; the surrounding context explains what to record and how to judge the result.
Tool guide at a glance¶
Create a filtered event timeline and explain one high-value sequence.
A supplied EVTX set with host, channel, audit, and time-zone context.
A validated event sequence with complete fields, surrounding records, and corroboration.
Evidence and safety
Treat rule matches as leads. Preserve EVTX files and do not rely on an event title or identifier alone. Record the input identifier, tool version, relevant commands or settings, time and time zone, output location, and any errors or limitations as you work.

How the labs complement this guide
The Interactive Lab is a safe browser simulation for practising the workflow and validation logic. The Full Lab is an independent exercise for an isolated, authorised environment. Confirm the installed tool version and expected output before relying on either exercise in a real case.
