One of the biggest trends in infosec, besides the word cyber, is threat hunting. First, I want to start by defining threat hunting as the action of “investigation without cause” and this concept is nothing new. It’s been around for years but we didn’t have a catchy marketing term associated with it. In this post, I will breakdown the Sqrrl threat hunting model, Powershell Empire for adversary activity, and instructions on setting up Graylog for log aggregation and a search platform to perform threat hunting. Finally, I would like to point out all Ansible playbooks used in this post are publicly accessible on my Github page in a repo called “AgileFalcon“.
