Wireless presentation controllers prove juicy targets for hackers

Tim Stevens

Wireless presentation controllers have changed corporate life forever. Instead of businessmen and women staying tethered to their keyboards while delivering boring PowerPoint presentations, they can wander about the room, gesticulating authoritatively with an ego-boosting gadget in-hand... while delivering that same boring presentation. Now a security researcher by the name of Nields Teusink is showing that those wild gesticulations open the door to crazy hacks, with most wireless presenters being recognized as full keyboards -- some even as keyboards and mice. With no encryption provided it's a (reasonably) simple task for an attacker to replicate the signal, escape the presentation, and completely compromise the machine. Teusink uses an Arduino board for his work here, impressing us while sending a chill into the hearts of slide gurus everywhere.
