We then perform a brute-force attack or a dictionary attack on the captured handshake.

This allows us to capture the four-way handshake.

The de-authenticated client then reconnects to the access point.

Then the properly configured network interface card is used to perform a de-authentication attack.

That is the network interface card is set to monitor mode and can perform packet injection.

The attacker first configures his/her own network interface card.

Now let's see how the methodology is used in a real-world attack scenario with the help of the diagram given below. This is a resource-intensive task and the time is taken may wary depending on the wordlist and CPU speed.

In the final stage, we run a brute force attack against the captured handshake.

You may not capture a handshake right away so all you need to do is wait.

In the fourth stage we finally capture the four-way handshake, this step involves a bit of patience.

We can also perform several other types of attack at this stage such as Fragmentation attack, MAC-spoofing, Man-In-The-Middle attack, Evil twin attack or a dos attack to disable the AP. For this step, we need the MAC address of the client and the access point. The third stage is to de-authenticate a client connected to a specific access point so we can capture a four-way handshake.The second stage is gathering information on nearby access points. Information such as MAC address, Channel number, Authentication type, and clients/stations connected to a specific access point.The first stage involves configuring the WiFi adapter to set it in monitor mode also called promiscuous mode, with this mode enabled the wifi adapter can capture packets that might or might not be aimed at them.WiFi hacking approach takes place in five simple steps

Because we know that both ethical and non-ethical hackers use these tools, Techofide will not be held liable for any unlawful/false actions you engage in.

Note: We're only teaching you for educational purposes and to broaden your horizons. Then we will go ahead and crack the WAP/WAP2 wireless network.Īt the end of this blog, I have also included a video of the Aircrack-ng Tutorial for your ease that will show you how to hack wifi in real life. We are going to discuss what are pre-shared keys, what is packet injection, then we will verify if your Network Interface Card (NIC) supports packet injection. This guide will show you how to crack pre-shared key WPA/WPA2 networks using the Aircrack-ng tool, which is used to crack wifi passwords.
