How to Hack an ATM

Tiffany Rad is a hacker herself, as well as a lawyer and an academic. She first got into it because she wanted to see if she could hack her own car. That's breaking into real world objects that are controlled by computers like an ATM. Barnaby worked out how to get an ATM to spew all its money into a giant pile using just computer code. He didn't even need physical access to the machine, he could do it all remotely over the internet.
