Wi-Fi Security

Wi-Fi security is one shared secret stretched across every attack you run against it. WPA2 proves you know the PSK without sending it — which is exactly why a captured handshake (or a single PMKID) is a self-contained offline puzzle you grind with hashcat. KRACK broke the protocol itself, WPA3 tried to close the door, and Evil Twin / Karma skip the crypto entirely by getting the user to hand over the secret. How each works on the air, the real tools, and where the defences actually hold.
