AirMagnet secures patent to detect counterfeit Wi-Fi access points

I was highly intrigued to learn that AirMagnet, a WiFi security specialist, has secured a US patent on "multiple methods of identifying spoofed or counterfeit devices in a wireless LAN..."

According to the WiFi security firm, device spoofing is a "basic technique of wireless hackers and attack tools that routinely attempt to spoof the identity of another wireless device."

Phew - what a long-winded explanation!

The idea behind wireless device spoofing, the company says, is not always to fool people to log into the wrong network, but also to gain unauthorised access to a legit network.

Perhaps worse, the firm says that some people use device spoofing to hide the source of a wireless network attack.

Chia-Chee Kuan, AirMagnet's chief technology officer, claims that hackers are using access point spoofing as the first step in man-in-the-middle attacks, as well as carrying out certain types of denial-of-service attacks.

Kuan says that wireless device spoofing is also being used as a method of intrusion to a wireless network, and even to avoid detection as a rogue access point.

"The techniques covered in this allowed patent application enable us to detect threats to a WLAN immediately from the onset of an attack," he said.

Interesting stuff eh? Read more about Kuan's company patent here...
