Brocious’s work is popular in the information security community because it abuses basic security design flaws, so it is a perfect place to begin understanding security issues surrounding electronic door locks. THE ONITY DOOR LOCK The Onity HT door lock is extremely popular. If you’ve stayed at hotels, you’ve likely encountered it and implicitly relied upon its mechanisms for your safety and privacy. As shown in Figure 2-1, the Onity lock consists of a magnetic key card reader. Hotel guests are issued magnetic key cards, which open the locks when swiped through the readers.

Of course, it is not possible to easily ascertain exactly what doors the newly created spare card might open, which makes this attack a little difficult to execute. VENDOR RESPONSE On July 24, 2012, Brocious revealed his research and his paper to the world, providing anyone armed with a cheap Arduino board with all the information needed to break into millions of hotel rooms. This also alerted the public to the risk they were taking when staying in hotel rooms protected by the Onity lock. Onity was put under scrutiny by the public and hotel owners, who looked to it to provide a solution to the problem.

When spare cards are created in a batch (to be used with programming cards), each subsequent card has an incremental ident value. 40 CHAPTER 2: ELECTRONIC LOCK PICKING—ABUSING DOOR LOCKS TO COMPROMISE PHYSICAL SECURITY When a guest inserts a card into the lock, the data on the card is decrypted using the sitecode. Next, the expiration date is checked to see if it is still valid. Finally, the keycode value is checked and the lock opens if it is within the look-ahead range. THE PROGRAMMING PORT A programming port, accessible using a DC adapter, is located at the bottom right of the lock.
