WLAN Hacking – WPA-PSK handshake. The deauth atack with Aireplay-ng -0 wants to disconect the client from Access Point and after reconnecting get by tapping the handshake. But the process fails. Now what? Be aware that there is another (maybe better and easier) way how to get the data for crack WPA. Wireshark is a strong application and the technology that will be described can be used in other ways like for universal sniffing of the net traffic.
