[News] Kestrel session at Black Hat USA 2023_
Kestrel is a threat hunting language aiming to make cyber threat hunting fast by providing a layer of abstraction to build reusable, composable, and shareable hunt-flow. Starting with:
#. Black Hat USA 2022 session recording_
#. Black Hat USA 2022 Kestrel hunting lab_
#. Kestrel live tutorial in a cloud sandbox_
Software developers write Python or Swift than machine code to quickly turn business logic into applications. Threat hunters write Kestrel to quickly turn threat hypotheses into hunt-flow. We see threat hunting as an interactive procedure to create customized intrusion detection systems on the fly, and hunt-flow is to hunts as control-flow is to ordinary programs.
What does it mean by hunt fast?
