This new hacker invention may look like a harmless dry erase marker, but in truth it's the ultimate electronic lock pick.
In a post titled 'James Bond's Dry Erase Marker,' hotel hacker Matthew Jakubowski demonstrates how anyone can build this pocket-sized device which will open the lock on an estimated 4 million hotel rooms.
'I guess we wanted to show that this sort of attack can happen with a very small concealable device,' says Matthew Jakubowski, a security researcher with Trustwave, told Forbes. 'Someone using this could be searched and even then it wouldn't be obvious that this isn't just a pen.'
The device exploits a vulnerability in Onity locks, a cheap lock used on millions of hotel room doors.
Onity's site boasts their locks are used in 22,000 hotel worldwide.
The lock has a small port on its bottom designed for hotels to set master keys.
Hacker Cody Brocious discovered you could read the lock's memory through this port, including a decryption key.
Borcious demonstrated a large, unwieldy device that could open a small percentage of locks this July at the Black Hat security conference.
Onity responded with a way to patch the weakness in August, but the fix required hotels to make costly hardware repairs to millions of locks as well as pay for a more secure version.
Security experts believe the expense has likely left a huge percentage of hotel rooms with the easily cracked model.
Jakubowski's refined version can pop most locks in a fraction of a second.
Even if security searched a guest, its unlikely many people would see a dry erase marker as a threat.
And future versions may be even smaller and easier conceal.
