Noted that cracking into a network that is not yours or you do not have permission to is illegal. All of the networks in the follow article were owned by myself or agreed with the network administrator that these brute force attacks were going to be attempted. General Idea Hacking into Networks has a long history. Ever since the advent of the wireless networking, and obvious challenge is securing pieces of data over this non visible network. There have been various attempts at securing this phenom. These security attempts come in a few flavors called: Wired Equivalent Privacy (WEP) Wi-Fi Protected Access (WPA) Wi-Fi Protected Access II (WPA2) All of these methods have proven secure for a periods of time but have been cracked — either due to a actual security flaw, implementation errors, innate build flaws. Our modern day standard WPA2 suffers from build issues check out KRACK attacks — https://www.krackattacks.com/ Attack vector Set hardware to listen to all packets Capture network frames Chose Base-Station and Client Listen to Base-Station traffic Send DeAuth frame as client Capture the Handshake!
