Hack WiFi with Denial of Service Attack is the best and fastest way to this.

The first step to hack WiFi is to do the following

Open a Terminal

Now that we’re positioned within range of the wireless access point for the exam, let’s fire up BackTrack and open a terminal. Let’s make certain our wireless adapter is recognized in BackTrack and functioning.

  • iwconfig

Step 2

Put the Wireless Adapter in Monitor Mode

Our next step is to put our wireless adapter in monitor mode with airmon-ng.

  • airmon-ng start wlan0

Step 3

Monitor the Available APs with Airodump-Ng

Now we want to take a look at all the access points in range by using airodump-ng.

  • airodump-ng mon0

As we can see, the access point for Concord University is the third access point displayed. Note its BSSID (this is its globally unique identifier based on its MAC address) and copy it.

Step 4

Connect to the Access Point

Now we need to connect to the AP with our computer.

We can see the connection at the bottom of screen. There we can see the access point’s BSSID on the far left bottom and the MAC address of our client following it. We need both of these bits of information for our next step in this hack.

Step 5

Broadcast Deauthenticate Users on the AP

Now we’re ready to deauthenticate (bump off) all the users from the AP. We need to send thousands of deauthenticate frames to keep any one from reconnecting to the AP. We can do this by typing the following into another terminal.

  • aireplay-ng –deauth 1000 -a 00:09:5B:6F:64:1E -h 44:6D:57:C8:58:A0 mon0

  • 00:09:5B:6F:64:1E is the BSSID of the AP.
  • 44:6D:57:C8:58:A0 is the MAC address of our computer.
  • 1000 is the number of deauthentication frames to send to the AP.

You could do this at your school. Now, the students attempt to connect to the AP to take the exam, they will be unable to connect, or as soon as they do, they’ll be disconnected because you hack WiFi. It’s unlikely that the teacher or professor will have any idea what’s happening, and for that matter, neither will the school IT director.
