Modernizing Authentication — What It Takes to Transform Secure Access REGISTER >
According to a US-CERT advisory, a vulnerability in Wi-Fi Protected Setup makes it dangerously easy for a hacker to determine the PIN that's required to set up a wireless router.
"The flaw results in too much information about the PIN being returned to an attacker and makes the PIN quite weak, affecting the security of millions of Wi-Fi routers and access points," writes Threatpost's Dennis Fisher.
"Security researcher Stefan Viehbock discovered the vulnerability and reported it to US-CERT," Fisher writes. "The problem affects a number of vendors' products, including D-Link, Netgear, Linksys and Buffalo. He said via e-mail that he has received essentially no response from vendors about the problem."
