Travel Technology News - Asia / Pacific.

New York (AirGuide - Travel Technology News Asia / Pacific) May 9, 2010

Chinease kits are being sold for easy cracking of WEP/WPA-protected networks Owen Fletcher reports from China for the IDG News Service that kits are being sold for easy cracking of WEP/WPA-protected networks. Fletcher apparently bought one for about USD24 (YEN165) at a bazaar, including setup help. The kit is a CD-ROM with software, a six-inch antenna and Wi-Fi adapter, and a live boot CD. While WEP is easily cracked, sometimes in seconds, WPA requires a large precomputed set of keys in the terabytes. The reporter cracked a 40-bit WEP key ("sugar") in an hour, which is quite a while. That implies that the router had only strong initialization vectors and other improvements in WEP that typically only forestall cracking by minutes. (With weak IVs, a subset of the counters used to create separate keying material for each packet, an older or unpatched router's key could be broken in 30 seconds to about 5 minutes.) May 6, 2010
