Crack Program Released for Wireless Nets
Only pre-shared key systems are affected. Dictionary attack, as a practical matter, affects only those with short, simple passphrases.One year after a vulnerability in the Wi-Fi Protected Access encryption algorithm was reported, a proof-of-concept program for the attack has been released. The attack affects only Wi-Fi networks using WPA in pre-shared key mode. It is a dictionary attack, meaning that it cycles through a list of words and combinations of words attempting to find one that matches the data on the network. Longer, more random passwords or passphrases, and enterprise implementations that use external authentication systems, are not affected by the vulnerability.
The group that released the crack program, Tinypeap, writes Wi-Fi-related software, including a small radius server for certain Linksys routers.
