Burglars Hacking Hotel E-Doors: At the Black Hat hacker conference this past July, independent security researcher Cody Brocious provided details about how to exploit a hardware bug in electronic doors used by many hotels. The technique allows a person to unlock the door and break into a hotel. The Houston Hyatt as well as three other hotels in Texas have been hit using this technique and at least one man has been arrested and charged. The technique involves inserting a digital probe into a small hole on the door lock mechanism, which reveals the combination for the lock.The Hyatt Houston said it had taken steps to harden doors against attack by filling the tiny hole with thick glue.
