Modern facilities (such as corporate headquarters) are marvels of engineering. These buildings employ numerous embedded and software systems to help ensure convenience, efficiency, and even security. The door that unlocks after you swipe your badge is managed by an access control system. The lights and even power to your building are managed by a facility management system. These invisible embedded and software systems make modern life in the corporate headquarters convenient and comfortable. What if someone were to take over these systems? Join us as we demonstrate what can happen when these systems are compromised. We'll cover various vulnerabilities that exist in access control systems, facility management systems, and other systems that support modern buildings. We'll show real examples of how these systems can be exploited to unlock the front door to your corporate headquarters, disrupt business operations, and even shut the lights off in your building.
