Hacker invention called James Bond’s Dry Erase Marker is invented by hotel hacker Matthew Jakubowski who demonstrates how anyone can build this pocket sized device which will open the lock on an estimated 4 million hotel rooms.
Hacked: an electronic lock pick concealed in a dry erase marker could come in handy on James Bond’s secret missions
The device exploits a vulnerability in Onity locks, a cheap lock used on millions of hotel room doors.
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.

Lockpick: The harmless looking device easily accesses millions of hotel locks
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.
‘This is by no means the best solution or the only solution to make this fit into a pen, but for what we had available and with the time we had to do it, it’s what we were able to come up with,’ Jakubowski wrote in a blog post explaining the hack.
