This is opposed to an offline attack, such as WPA handshake brute-forcing, which does not require you to be connected to the network to succeed. While it did require a hacker to be within range of the target Wi-Fi network, it was able to penetrate even WPA and WPA2 networks with strong passwords using an online attack.
Worse, the 8-digit-long PIN could be guessed in two separate halves, allowing for the attack to take significantly shorter than working against the full length of the PIN. Reaver allowed a hacker to sit within range of a network and brute-force the WPS PIN, spilling all the credentials for the router. One of the first practical attacks against WPA- and WPA2-encrypted networks, it totally ignored the type of encryption a network used, exploiting poor design choices in the WPS protocol. The Reaver brute-force attack was a radical new weapon for Wi-Fi hacking when it was presented in 2011. Reaver: Now Obsolete Against Most Modern Routers Years later, another attack emerged that remains effective against many routers and greatly reduces the amount of time needed to attack a target. WPS PINs have been attacked by two successive generations of attacks, starting with the most basic brute-forcing methods targeting the way some routers split the PIN into two separate halves before checking them.
And one weakness many access points have is a feature called Wi-Fi Protected Setup, which we will learn how to exploit in this guide.ĭon't Miss: How to Crack Weak Wi-Fi Passwords in Seconds with Airgeddon on Parrot OSĪ WPS PIN on the bottom of a router can be seen here. Since the source of the Wi-Fi signal is being broadcast from the router's hardware, the device itself would be a great target to attack instead of the encryption. In some cases, an access point's encryption is not the weakest point of the network, so it's good to think outside of the box, or, in this case. While WEP networks are easy to crack, most easy techniques to crack WPA and WPA2 encrypted Wi-Fi rely on the password being bad or having the processing power to churn through enough results to make brute-forcing a practical approach. When attacking a Wi-Fi network, the first and most obvious place for a hacker to look is the type of network encryption.
To do this, a modern wireless attack framework called Airgeddon is used to find vulnerable networks, and then Bully is used to crack them. While this tactic used to take up to 8 hours, the newer WPS Pixie-Dust attack can crack networks in seconds. Design flaws in many routers can allow hackers to steal Wi-Fi credentials, even if WPA or WPA2 encryption is used with a strong password.
