In my case, the interface name of my USB wireless adapter is wlan0. To set the network adapter to monitor mode, first find the name of the interface as your system detects it. This means we’ll be able to see nearby wireless access points and devices connected to each one. Monitor mode allows the wireless network interface to capture all wireless traffic. We’ll need to set up monitor mode in our wireless network adapter. For Windows users, refer to the official aircrack-ng site to download the suite. If you’re not on Kali Linux, aircrack-ng is most likely available through your preferred package manager. I have the Panda Wireless N600 and it works perfectly fine on my Macbook Pro. You can also do what I did and buy a cheap USB wireless adapter with these capabilities. There’s a good guide on the aircrack-ng site that can help you with research. Feel free to do some research about your particular card and it’s compatibility. To use aircrack-ng you’ll need a wireless network adapter that has monitor mode and packet injection capabilities.
It can be used to scan wifi signals and to perform denial-of-service (DOS) attacks. Do not try to break into access points that do not belong to you.Īs described on the official aircrack-ng website, aircrack-ng is a complete suite of tools to assess WiFi network security.
aircrack-ng is already included on Kali Linux but you can install it on any Linux OS.ĭisclaimer: This is purely for educational purposes. I used Kali Linux for the entire process, but the process should be very similar for any Linux distribution. Perhaps I’ll write a post using that tool in the future. In fact, I discovered bettercap earlier this year and it is easy to use. There are other methods of doing this as well. The difficult part is guessing the password to a router due to processing power needed, but sniffing wifi networks is a trivial process. Learning to use aircrack-ng and break into my own router was both fun but also a bit shocking as to how easily someone could do this. This post is essentially a re-write of notes I took around 2 years ago.
