Resumen Las vulnerabilidades en el protocolo WPA2 permiten la manipulación del proceso de handshake entre un cliente y un Punto de Acceso (AP, por sus siglas en inglés) induciendo la reinstalación de la clave de sesión y otros parámetros utilizados para el cifrado de los mensajes transmitidos, lo que deriva en la manipulación de los mensajes enviados y transmitidos, el.

Security advisory for OBSO Security Advisory Report - OBSO WPA2 Protocol Four-way Handshake Handling MitM Issue (KRACK attack) Creation Date: Attack on Windows authentication mechanism. At the recent BlackHat Europe conference (November 10 – 13, Amsterdam) a security researcher called Ian Haken presented a very interesting, simple yet powerful attack allowing to bypass Windows (Kerberos) authentication on machines being part of a Domain.
