What is Reaver?

“Reaver” in the context of Linux refers to a specific tool known as “Reaver-WPS.” Reaver is a popular open-source command-line tool used for performing brute-force attacks on WPS-enabled (Wi-Fi Protected Setup) routers.

Its primary purpose is to crack the WPA/WPA2 pre-shared key of a Wi-Fi network by exploiting the WPS vulnerability.

In this Kali Linux Tutorial, we are to work with Reaver. Reaver has been designed to be a handy and effective tool to attack Wi-Fi Protected Setup (WPS) register PINs keeping in mind the tip goal to recover WPA/WPA2 passphrases.

Presently hacking WPA/WPA2 is exceptionally a tedious job. A dictionary attack could take days, and still will not succeed.

WPS-functionality always stopped to work somewhere between 2 and 150 failed authentication attempts. The functionality did not even return after several hours. I would consider this a bug in the firmware which causes a DoS rather than lock-down functionality. Researchers said.

All major suppliers (counting Cisco/Linksys, Netgear, D-Link, Belkin, Buffalo, ZyXEL, and Technicolor) have WPS-affirmed gadgets, completely different sellers (eg. TP-Link) send gadgets with WPS support that aren’t WPS-certified.WPS is enabled default by all devices.
