Episode 13: BloodHound 10-Year Anniversary Pt. 1

In this episode of Know Your Adversary, Jared Atkinson and Justin Kohler are joined by Andy Robbins, Will Schroeder, and Rohan Vazarkar, the original creators of BloodHound, to celebrate ten years since the tool was first introduced. Together, they revisit the offensive security challenges that led to BloodHound and how a need to understand increasingly complex Active Directory environments ultimately led them to graph theory and attack path analysis.
The discussion traces BloodHound's evolution from a tool built by red teamers to solve their own operational problems into an open source project that changed how practitioners understand identity-based attack paths. The group shares stories from its early development and DEF CON debut, the expansion from a simple graph of three node and edge types, and the realization that BloodHound wasn't creating attack paths, but providing a map of relationships and opportunities that had been there all along.
Along the way, they explore how BloodHound changed offensive tradecraft, why visualization made complex attack paths easier to understand, and how defenders began using the same capabilities to find and eliminate those paths at scale. They also reflect on the project's transition from an offensive tool toward a defensive capability, setting the stage for BloodHound Enterprise and the next chapter of BloodHound's evolution.
