Time for action – bypassing Open Authentication

Let us now look at how to bypass Open Authentication:

1. We will first set our lab access point Wireless Lab to use Open Authentication. On my access point this is simply done by setting Security Mode to None:

   

2. We then connect to this access point using the command iwconfig wlan0 essid "Wireless Lab" and verify that the connection has succeeded and that we are connected to the access point:

   

3. Note that we did not have to supply any username / password / passphrase to get through Open Authentication.

What just happened?

This is probably the simplest hack so far. As you saw, it was not trivial to break Open Authentication and connect to the access point.
