Perimeter Breached: Hacking a Network-Connected Access Control System

Sam QuinnSteve Povolny

Sam Quinn and Steve Povolny analyze building access control hardware, uncovering vulnerabilities in Mercury controllers that allow remote physical door unlocking.

Summary

The Convergence of Physical and Network Security Perimeters

Enterprise physical access control systems (PACS) increasingly connect directly to IP networks, creating potential bridges between digital vulnerabilities and physical facility access.

Reverse Engineering Mercury Security Access Controllers

Sam Quinn and Steve Povolny audit Mercury EP-series controllers, discovering unauthenticated command execution and hardcoded cryptographic keys in backend daemons.

Remotely Unlocking Doors and Spoofing Badge Scans

The researchers demonstrate weaponizing discovered flaws over the network to instantly trigger door strikes, unlock secured zones, and forge audit logs.

Hardening Guidelines for Corporate Facilities Teams

The presentation provides enterprise defenders with network segmentation blueprints and firmware update practices for physical access infrastructure.
