A security researcher named Barnaby Jack amazed attendees at the Black Hat security conference by hacking ATM machines in a session titled "Jackpotting Automated Teller Machines Redux". There are some important lessons to be learned from the hacks Jack demonstrated, and they apply to more than just ATM machines.
Jack's exploits--one involving physical access to the ATM machine using a master key available online, and the other dialing in remotely to gain access--focused on ATM machines from Triton and Tranax. However, the issue is not necessarily limited to these two. Jack explained to his audience that he has yet to find an ATM machine that he couldn't crack and retrieve cash from.

It's an impressive hack. Who wouldn't like to just walk up to an ATM machine and cause it to spew money as if you'd hit the jackpot on a Vegas slot machine? But, most businesses don't own ATM machines, so why should IT admins care about the ATM hack?
