Automatically crack WEP & WPA networks with Besside -ng

Hello aspiring ethical hackers. In our previous article, WiFi hacking, you have learnt all the basics you need to learn about auditing wireless networks. In this article, you will learn about a tool Besside -ng, which can automatically crack WEP passwords and log WPA handshakes. This tool authored by Andrea Bittau is made in the line of another tool, Wesside-ng which can only crack WEP passwords automatically.

Let’s see how this tool works. For this we will be using Kali Linux as Besside-ng is installed by default on it. We will also need a Wifi adapter that allows packet monitoring. For this, we will be using ALFA AWVS036NHA wifi adapter.

Before you run Besside-ng, monitor mode should be enabled on the wireless interface as shown below.

Once monitor mode is enabled on the wireless interface, we can run Besside-ng as shown below to automatically crack all the WEP passwords and log WPA handshakes.

If you want to crack the WEP password of a single Access Point, the command is as shown below

where “-c” is used to specify the channel the Wireless Access Point is running on and “-b” is the –bssid of the Wi -Fi access point.

how to use besside to crack wifi passwords

Besside-ng automatically starts creating traffic and cracking the WEP key as shown below.

As you can see in the above image, it cracked a 64bit ASCII WEP key in less than 1 minute. How about 64 bit hexadecimal WEP key that’s a bit complex.

This key was cracked in 63 seconds. How long it will take to crack the same key we cracked earlier with aircrack?

It took just 45 seconds to crack the password. This time, I generated a complex WEP key and tried again. The key was cracked in around 15 minutes as shown below.
