"Of all tyrannies, a tyranny sincerely exercised for the good of its victims may be the most oppressive. It would be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience." --C.S. Lewis

Hacking RFID Chips

Radio Frequency ID chips, those increasingly ubiquitous chips found in some consumer products make inventory control a breeze for retailers, but of course, there's a glitch. Hackers have found a way to reprogram RFIDs using PDA's:

A would-be scofflaw heads into a grocery store where all the products have RFID tags on them. Rather than paying $7 for a bottle of shampoo, he'd rather pay $3. To make that happen, he whips out a PDA equipped with an RFID reader and scans the tag on the shampoo. He replaces that information with data from the tag on a $3 carton of milk and uploads it to the shampoo bottle tag. When he reaches the check-out stand--which just happens to be automated--he gets charged $3 instead of $7, with the store's computer systems none the wiser.

Industry is catching on, making RFID's more secure but I'm betting hackers will continue to 'end-run' new technology.
