DEF CON 27 - WillC - Phreaking Elevators


This is a comprehensive dive into the current emergency phones with an in-depth look at the phones used in elevators. This talk will provide unique insight into a topic that hasn't been covered before: Elevator Phones. During this talk, I will discuss the commonality between elevator phone brands. I will cover a new, never before released, set of default passwords these system use. I will show a tool kit and how to use it to access elevator phones locally, as well as remotely. In addition, I will show how to reprogram a phone , how to make the elevator state its location, and how to alert the passenger that help is on the way. Finally, I will demonstrate some attacks, including how you can use elevator phones as listening devices to silently listen to conversations of people inside an elevator. I'm WillC, your elevator operator, let's go for a ride!
