Wi-Fi Fingerprints — the End of MAC Spoofing? from Slashdot.

Wireless devices can be identified by variations in their radio signaling, known as their ‘transceiverprint,’ according to research reported in Techworld. The Canadian researcher, Jeyanthi Hall, related the prints to MAC addresses and got a positive ID for devices connecting to a Wi-Fi network, claiming 95% success with no false positives. Once they work out how to do this without a dedicated signal analyzer and neural network processing, it’s the end of MAC spoofing on wireless networks.

Interesting comments ;-) nweaver:

Cool hack, but who cares. With proper authentication (eg, WPA), you don’t need to worry about MAC spoofing as the packets won’t authenticate right to the access point.

You are forgetting the insider threat. I might have the WPA key because I am an employee with my own laptop. However, if I spoof your MAC, then it looks like you are the one surfing (or porn sites) all day and not me. Encryption is good, but it doesn’t solve every security problem.
