CHIP + PIN + HACK = TETRIS

Two researchers at Cambridge University, Steven Murdoch and Saar Drimer, recently reported their success at hacking a chip-and-PIN terminal to make it play Tetris. As reported in The Register, "The proof-of-concept hack highlights wider security concerns about the terminals even though it was only possible after Murdoch and Drimer replaced most of the internal electronics after opening up the terminal." The researchers also did a short video that is now available (presumably to no one's surprise) on YouTube.
