10 years ago this month, Eric Hutchins (aka @killchain), @mikecloppert and I published a paper to share analytical tradecraft we had been using to defend networks against Advanced Persistent Threats - aka the “cyber kill chain”. bit.ly/killchain. (Thread) 1/ Officially, “Intelligence-Driven Computer Network Defense Informed by Analysis of Adversary Campaigns and Intrusion Kill Chains”. We thought that sounded more academic.

Some thoughts on leadership. Early in my career I worked with some great guys like @PahDoh @killchain. We used to joke about the ‘employee recognition program’ - normally when you passed the senior leader in the hallway he would barely look at you. 2/ At some point he would look at you and grunt as you passed. The grunt meant you were now recognized. Thus, the employee recognition program was born!
