About

I am an offensive engineer and red teamer who works for SpecterOps and formerly worked for Veris Group’s Adaptive Threat Division. I am a co-founder and active developer of:

• Empire/EmPyre – a pure PowerShell/Python post-exploitation agent (Slack channel invite here)
• BloodHound – an graph-based Active Directory analysis tool (Slack channel invite here)
• GhostPack
• PowerView and PowerUp
• Veil-Framework – an AV-evasion framework

I’m also an active PowerSploit developer and a Microsoft PowerShell/CDM MVP.

I’ve presented at ShmooCon, BlackHat, DEF CON, DerbyCon, CarolinaCon, Troopers, BlueHat Israel, and several Security BSides conferences on topics spanning AV-evasion, Active Directory, post-exploitation, red team tradecraft, BloodHound, and offensive PowerShell. I also formerly co-developed and taught the “Adaptive Red Team Tactics” and “Advanced PowerShell for Offensive Operations” Black Hat training classes, and currently develop the “Adversary Tactics: Active Directory” and “Adversary Tactics: Red Team Operations” training courses.
