Wireless How To

Finding the Four-way Handshake

To make sure we captured a authentication handshake, we can use the network protocol analyzer Wireshark (formerly Ethereal). Wireshark allows us to view packet contents and sort by type of packet captured to pull out the WPA handshake.

Open up Wireshark (Backtrack > Privilege Escalation > Sniffers) and open the Kismet capture "dump" file (Kismet-<date>.dump) to view all the captured packets. The WPA four-way handshake uses the Extensible Authentication Protocol over LAN (EAPoL).

Using Wireshark, we can filter the captured packets to display only EAPoL packets by entering "eapol" in the filter field (Figure 7).

Here, we're basically looking for four packets that alternate source, client-AP-client-AP (I've highlighted them in red in Figure 7).

Now that we've confirmed that we've captured a four-way handshake it's time to perform the crack.
