![]() ![]() ![]() Most important is the fact that the PIN used to complete the setup of wireless router could be broken in smaller parts that could be attacked separatelly. In 2011, the researcher Stefan Viehböck demonstrated several design flaws in WPS. Usually an efficient attack against the WPS required up to 11,000 guesses, which is a small number of attempts that could be executed approximately in four hours. The offline calculation allows the attacker to remain under the radar because he doesn’t need to try all possible combinations of digits that compose the numerical password. The brute-force attack exploits weak randomization for the generation of a key used to authenticate hardware PINs on some implementations of WPS, the attackers can collect quickly information that allows them to guess the PIN through offline calculations. The WPS is a popular network security standard that allows users to easily secure a wireless home network, but it knows that threat actors could brute-force it if the network’s access point is not properly configured. ![]()
