Why Static Proximity Cards Are Dangerous
February 26, 2010I’m setting up another HID Prox security demonstration. I’ve cleaned up my equipment so it doesn’t look quite so hacked-together. I’m working on some long-range antennas and the code to safely support them. Once it is all working, I hope to be able to…
- Sniff cards being read across the room by a legitimate reader
- Flash a room and read card responses
- Brute-force desired bits on a proximity card
Already I can read a card to capture its number at short-range with a variety of readers. With the card’s number, I can easily retransmit to a reader. Basically, the existing system I’ve assembled lets me read your card and use it later at my leisure.
