I've always liked the scene in Terminator 2 where John Connor walks up to an ATM, interfaces his Atari to the card reader and retrieves cash from the machine. I think I've got that kid beat. The most prevalent attacks on Automated Teller Machines typically involve the use of card skimmers, or the physical theft of the machines themselves. Rarely do we see any targeted attacks on the underlying software. I will demonstrate both local and remote attacks, and reveal an ATM rootkit. Finally, I will discuss protection mechanisms that ATM manufacturers can implement to safeguard against these attacks.
