Users of Old Wi-Fi Security Vulnerable to New Attack.

The article focuses on issues related to the use of Wired Equivalent Privacy (WEP), an outdated and vulnerable Wi-Fi security protocol, by several businesses and home users in the U.S. A WEP vulnerability was behind the biggest known U.S. data breach, at retail giant TJX in 2007. Hackers gained access to 94 million payment card numbers. But the latest proof-of-concept breach should be even more of a clarion call to trade in WEP for the superior Wi-Fi Protected Access (WPA). An attacker using security researcher Vivek Ramachandran's "Cafe Latte" technique, as it is known, could break through WEP protection on a client machine, such as laptop, in the time it takes to enjoy a cup of coffee.
