DEF CON 29 (2021),
Aug. 8, 2021, noon
(45 minutes)
Since the late great Barnaby Jack gave us "Jack Potting" in the late 2000s, there have been several talks on ATM network attacks, USB port attacks, and digital locks attacks which apply to several brands of ATM safes. In this session, I'll discuss and demonstrate how most of these known attack vectors have been remediated, while several fairly simple attacks against the machine and the safe still remain. We'll dive into how ATMs work, the steps I went through to become a "licenced ATM operator" which enabled my research, and how I identified the vulnerabilities. I'll show how, with very little technical expertise and 20 minutes, these attacks lead directly past "secure" and allow attackers to collect a lot more than $200.
