Cafe Latte attack steals data from Wi-Fi PCs

October 17, 2007 from NetworkWorld – “If you use a secure wireless network, hackers may be able to steal data from your computer in the time it takes to have a cup of coffee. At the Toorcon hacking conference in San Diego this coming weekend, security researcher Vivek Ramachandran, will demonstrate a technique he's developed to attack laptops that use the WEP (Wired Equivalent Privacy) encryption system to log on to secure wireless networks.

Developed in the late 1990s, WEP was the default method of securing Wi-Fi networks. Though the WPA (Wi-Fi Protected Access) system replaced it, about 41 percent of businesses continue to use WEP. That percentage is even higher among home users, security experts say.

That's unfortunate because WEP has been riddled with security problems. In fact, WEP was blamed for the recent TJX Companies Inc. data breach in which thieves were able to access 45 million credit- and debit-card numbers."
