Hackers Break Into Hotel Rooms with Key that Looks Like a Dry Erase Marker

What's Going On

The security researchers who spend their days breaking into clients’ systems to find and fix security vulnerabilities often call themselves “penetration testers,” or “pentesters.” But one group of hotel lock hackers just gave the term “pentest” a very different meaning.

A trio of hackers have built a tool that appears to be an innocent dry erase marker, but when inserted into the port on the bottom of a common form of hotel room keycard lock triggers the lock’s open mechanism in a fraction of a second.

“I guess we wanted to show that this sort of attack can happen with a very small, concealable device,” says Matthew Jakubowski, one of the three hotel lock hackers and a security researcher with the consultancy Trustwave. “Someone using this could be searched and even then it wouldn’t be obvious that this isn’t just a pen.”
