Offline attack shows Wi-Fi routers still vulnerable

The research, originally demonstrated at the PasswordsCon Las Vegas 2014 conference in early August, builds on previous work published by Stefan Viehböck in late 2011. Viehböck found a number of design flaws in Wi-Fi Protected Setup, but most significantly, he found that the PIN needed to complete the setup of a wireless router could be broken into smaller parts and each part attacked separately. By breaking down the key, the number of attempts an attacker would have to try before finding the key shrunk from an untenable 100 million down to a paltry 11,000—a significant flaw for any access-control technology.

WiFi Protected Setup Flaw Can Lead to Compromise of Router PINs

Posted on by

WPS is a method for setting up a new wireless router for a home network and it includes a way for users to set up the network via an external or internal registrar. In this method, the standard requires a PIN to be used during the setup phase. The PIN often is printed somewhere on the wireless router or access point. The vulnerability discovered in WPS makes that PIN highly susceptible to brute force attempts.

“I noticed a few really bad design decisions which enable an efficient brute force attack, thus effectively breaking the security of pretty much all WPS-enabled Wi-Fi routers. As all of the of the more recent router models come with WPS enabled by default, this affects millions of devices worldwide,” Viehbock said in a blog post.
