If the password you’re trying to crack isn’t in the passwords list, also called wordlist, then we won’t be able to crack it.In our tutorial we’ll use a popular list of passwords, called rockyou.txt, that comes with Kali Linux.When the hashes match, this means that we found the password.Next we’ll use a large list of popular passwords, and we’ll turn each one into a hashed form, and compare them with the WiFi password, in it’s hashed form, that we got from listening to packets. We won’t be decrypting the hashed password, but it still provides a valuable clue.

We want to capture these packets, because some of them will contain the hashed password. Target a single WiFi network from which we’ll try to capture Handshake packets – these are packets transmitted between the router and the client computer, when they’re trying to establish a connection.Set our wireless network adapter in monitor mode so it can listen for packets.To give you a short and simple overview so you know what’s coming up, we will: Boot your Kali Linux machine, and we can begin to crack WiFi passwords.

Up to this point, I believe you now have the basic knowledge required to get you started with Network hacking. In Monitor Mode, the card will listen to all packets being sent by the router capturing as many packets as possible. Therefore, we will set our NIC to Monitor Mode. To crack a WPA or WPA2 WIFi, we need to capture many of these packets. That means it can only listen to packets sent directly to our device (packets with our devices’ MAC address as the destination MAC). This chip is responsible for capturing packets sent by the router to our device.īy default, it is set to Managed Mode. This tutorial will teach you how to capture these packets and use them to crack WPA and WPA2 passwords.Įvery device with access to the internet comes with a chip known as the Network Interface Card ( NIC). Data transmitted between the client and the Access Point is known as Packets. To connect to the internet, a Device(A) will send a request to the router, which will, in turn, fetch what you want from the Internet. For example, if you are on a home network, the server would be the router/Access point. Whether you are on a wired or wireless network, one device is always considered a server. An excellent example of a resource that we connect to networks to access is the Internet. A network usually contains several devices connected using a wired (Ethernet, Fiber, etc.) or wireless connection (WiFi, Bluetooth, etc.) to share resources. Cracking WPA/WPA2 Using a Wordlistīefore looking at how to crack WiFi passwords, you need to understand how a network operates.
