Mind the Gap: Bridges, Backplanes, and BloodHound - HD Moore | BSides Las Vegas 2026
HD Moore — BSides Las Vegas 2026
Photos only — this session was not recorded, and I caught just two slides. Notes below cover only what those show.
The title names three things and the deck art names more — TCP/IP, OPC, and the industrial interconnects that sit between networks that are supposed to be separate. Bridges and backplanes are the parts of an estate that nobody inventories precisely because they are infrastructure for other things.
The pivot is to identity, where the same shape appears and is easier to demonstrate. BloodHound and OpenGraph keep proving the point, and the underlying dynamic is that mistakes compound with size and complexity.
Each grant is individually defensible. The graph they form is not, and nobody can see it without drawing it.
Frequently Asked Questions
What is the gap in Mind the Gap?
The space between systems that are supposed to be separate — bridges, backplanes and the interconnects that quietly join networks, alongside the same problem in identity where relationships between principals create paths nobody intended.
How does this relate to BloodHound?
BloodHound and OpenGraph make the identity version of the problem visible as a graph. The talk’s point is that mistakes compound with size and complexity: individually reasonable grants combine into attack paths that no one designed and no one can see without graphing them.
