Everything you need to know about wifi pentesting - KaliTut
The use of wireless WiFi networks has now become very common. Many users think about the security of their networks and computers, sometimes they have questions, how to hack WiFi, how real is this threat? In this article, I propose to ordinary users, perhaps far from the security audit questions of wireless WiFi networks, to look at their WiFi network through the eyes of a hacker, and even to wond

Key Reinstallation Attacks Breaking WPA2 by forcing nonce reuse Discovered by Mathy Vanhoef of imec-DistriNet, KU Leuven, 2017 Introduction We discovered serious weaknesses in WPA2, a protocol that secures all modern protected Wi-Fi networks. An attacker within range of a victim can exploit these weaknesses using key reinstallation attacks (KRACKs). Concretely, attackers can use this novel attack
