I read about some theoretical attacks on RFID:
- unauthorised usage: Black Hat walks onto train with rogue ID
sniffer, gets IDs of all tags in the carriage - this info might be
used to compute the relative value of each commuter's clothes and
belongings, and their origins. If RFIDs go into drivers licenses,
passports etc, then the presence of those documents will be revealed
without a search. If the RFIDs go into credit cards, Black Hat will
know how many, and which ones, you have. And if RFIDs go into cash,
then Black Hat will know how much you're carrying.
- replay attack: sniff a tag's ID, then later, play it back to the
detector and impersonate that tag
"Security professionals need to realize that RFID tags are dumb
devices. They listen, and they respond. Currently, they don't care
who sends the signal. Anything your companies' transceiver can
detect, the bad guy's transceiver can detect. So don't be lulled into
a false sense of security." --
