Are We Really Safe? Bypassing Access Control Systems
Dennis Maldonado analyzes vulnerabilities in commercial electronic access control systems, demonstrating Wiegand sniffing, RFID badge cloning, and physical request-to-exit bypasses.
Summary
Architecture and Background
Access control systems are everywhere. They are used to protect everything from residential communities to commercial offices. People depend on these to work properly, but what if I had complete control over your access control solution just by using my phone? Or perhaps I input a secret keypad combination that unlocks your front door?
Vulnerability Analysis
You may not be as secure as you think. The world relies on access control systems to ensure that secured areas are only accessible to authorized users. Usually, a keypad is the only thing stopping an unauthorized person from accessing the private space behind it. There are many types of access control systems from stand-alone keypads to telephony access control.
Exploitation and Demonstrations
In this talk, Dennis will be going over how and where access control systems are used. Dennis will walk through and demonstrate the tips and tricks used in bypassing common access control systems. This presentation will include attack methods of all nature including physical attacks, RFID, wireless, telephony, network, and more. Dennis Maldonado is a Security Consultant at KLC Consulting.
Remediation and Defensive Strategies
His current work includes vulnerability management, penetration testing, infrastructure risk assessment and security research. Dennis’ focus is encompassing all forms information security into an assessment in order to better simulate a real world attack against systems and infrastructure. As a security researcher and evangelist, Dennis spends his time sharing what he knows about Information Security with anyone willing to learn. Dennis has presented at numerous workshops and meetups in the Houston area. Dennis co-founded Houston Locksport in Houston, Texas where he shares his love for lock-picking physical security.
