From Network World's Brad Reed, who this week takes a look inside the new wireless security lab at Lockheed Martin:

Jason Crawford has learned that if you want to break into secure Wi-Fi networks, you don't need to buy equipment from the black market. Instead, you can buy it from Toys "R" Us, he says.

Crawford, who works as a principal investigator for R&D projects at Lockheed Martin's newly opened wireless-security laboratory, says he has figured out how to crack the seemingly secure wireless networks that consumers and corporations use — with nothing more than a cluster of eight PlayStation 3s. Crawford won't go into the details of just how he used the PS 3s to hack Wi-Fi networks, but he says that you don't have to be a top-level hacker to figure it out.
