Hotel-room Electronic Lock Security Hack

Cody Brocious found an exploit to open electronic hotel room locks in 200 milliseconds using an Arduino  (“connected to the OUTSIDE portion of the door lock”) to read the unencrypted security codes of the Onity-branded electronic lock.

This is the lock used on my last hotel room door.  So, while this does not qualify as Stuff I Like (except to my evil child self), I really like the guy’s t-shirt, above.
