How Barnaby Hacked ATMs

Barnaby connects a laptop to the port at the back of an ATM. The hotel realises it doesn't actually have the permission of the company that owns the machine. After his ATM hack, he began tinkering with medical devices like insulin pumps and pacemakers. And he would show just how he could get those devices to malfunction in potentially fatal ways. He wasn't aiming to give tutorials to criminals on how to murder people via their pacemakers or how to rob cash points. His goal was to highlight the flaws in systems so banks could make them more secure.
