Access to Your Hotel Room for Only $50 – Use That Safe!

If you haven’t seen this story on Tecca or in Forbes, Tecca reporter Fox Van Allen writes:

Between jewelry, passports, laptops, and even tablets, a lot of us carry some very expensive things when we travel. And we expect the hotel we’re staying at to do all they reasonably can to keep us and our belongings safe. But according to a Forbes report, hotel doors with keycard entry offer virtually no security at all — they can be easily hacked with as little as $50 worth of equipment.

According to 24-year old security expert Cody Brocious, if your hotel room door’s keycard lock has a DC power port, it can be broken in to with inexpensive software and other hacking tools. And to prove it, Brocious has created a device capable of breaking into as many as 5,000,000 hotel rooms worldwide. The device works by spoofing the all-access cards used by hotel staff. According to Brocious, while every locked hotel room door requires its own access code to open, that access code is programmed into the door itself. The hacking tool can read the code, and then use it moments later to unlock the door.

Brocious was presenting his hacking tool (and, more broadly, hotel room security) at the Black Hat USA security conference on July 24.

  1. Exactly why I DO use the safes, provided they are key (and not the same door card) – boy do I miss the physical keys of yesteryear.

  2. The safe in the room is not really all that secure. It has a little port on it to open it if you get locked out (has a little rubber cover). They just connect a handheld to it and it does its thing in a few seconds. One can assume it’s possible to get a device to unlock the safe the same way as this door card unlocking device.

    All I mean is don’t get a false sense of security. The hotel’s safe downstairs is secure, not those little things in the room!
