Use Proxmark 3 to read, replay, and clone RFID tags

AlexNguyen

I've attended the Hackfest conference in Quebec city last weekend. There was a presentation about physical pen testing techniques.

The speakers were doing a demo of the Proxmark 3. They showed how "easy" to clone a RFID tag (demo with the hotel access card) in just a few seconds.

Here are some web sites where you can order a Proxmark 3:

I've ordered a Proxmark 3 board with antennas. I've received it and made some testings. There's no driver for Windows 8. The driver works with a Windows 7 VM (VMware Workstation).

I tested with a HID card and it can read and replay when connected to a computer. I ordered an USB battery pack to use it in standalone mode. I also ordered some blank T5557 cards for cloning test.

LOL, and this is why I manually lock my hotel room at night. I also don't leave anything valuable in my hotel when I'm not there.

Yeah I always use the physical latch lock when I am in the room. Now if I would remember to quit being lazy and use the in room safe (if provided) when I am out of the room.....
