Scientists discover new vulnerability in WPS function on routers




Security researchers have found a method to crack. Wps the code of certain routers By some calculations, the code ‘guessed’ might be. Previously showed that wps is susceptible to a brute force attack.

The vulnerability was discovered by the Swiss security firm 0xcite, reports Ars Technica. Chipsets from Broadcom and a second, unnamed company would be susceptible by their own implementation of the WPS protocol. The Wi-Fi Alliance said in a reaction that vulnerability is not in the WiFi protocol itself. As many router manufacturers implement drawn by the chip manufacturers, many products are fragile, but it is not clear what exactly goes routers.

According to security researchers, the leak due to poor randomization generated numbers in some wps implementations. Therefore, the wps-code ‘guessed’ can be. With a series of calculations There is only one second to identify the wps code according to the discoverers.

Previously showed that the WPS protocol is susceptible to brute force attacks because there is no maximum number of attempts to make the code to guess and a security researcher discovered that the required PIN is divided into two pieces that can be attacked. Separately There are therefore needed to identify the code only 11,000 attempts something that takes several hours. The vulnerability is already known. Since 2011
