RFID: Time to Get Paranoid (Really)
In a recent Black Hat demonstration, RFID passport readers were reportedly "crashed" when a manipulated JPEG 2000 photo was included in an RFID-enabled passport. The corrupted image caused a "buffer overflow" fault in the readers by containing more data than was expected and halting the reading process. This has been hyped as a problem with RFID but the truth is that it was a reader programming oversight. The software should have rejected the data (and e-Passport) instead of allowing the buffer overflow to stop the reading program. What's the lesson here? That it's time for manufacturers and implementers of RFID to get paranoid. But in a good way.
It's clear that RFID is the technology target of choice for a growing number of hackers and security pundits. And, in some cases, RFID is an easy target because some implementers have an entirely unrealistic, benign view of the world. Many view RFID strictly as a new engineering or system tool that will provide real benefits.
