You should see output similar to what is below. Start listening to 802.11 Beacon frames broadcast by nearby wireless routers using your monitor interface: airodump-ng mon0 You should now see a new monitor mode interface listed (likely mon0 or wlan0mon). Next, we will place the interface into monitor mode: airmon-ng start wlan0 We will assume your wireless interface name is wlan0 but be sure to use the correct name if it differs from this. If you do not see an interface listed then your wireless card does not support monitor mode ? See here for more info.)īegin by listing wireless interfaces that support monitor mode with: airmon-ng

Have a wireless card that supports monitor mode (I recommend this one.

Have Aircrack-ng installed ( sudo apt-get install aircrack-ng).

If you are familiar with this process, you can skip the descriptions and jump to a list of the commands used at the bottom. An optional active deauthentication attack can be used to speed up the reconnaissance process and is described at the end of this document. The attack outlined below is entirely passive (listening only, nothing is broadcast from your computer) and it is impossible to detect provided that you don’t actually use the password that you crack. It is not exhaustive, but it should be enough information for you to test your own network’s security or break into one nearby. This is a brief walk-through tutorial that illustrates how to crack Wi-Fi networks that are secured using weak passwords.
