Are you sure you are ready to crack WPA? (1)

I caught a handshake packet, and spent a lot of effort to run the password out of the dictionary, but I couldn't connect to the wireless router at the end ......

Come on, and create an experiment together!

Step 1: Set up a wireless router for the experiment, as shown in Figure 1:

 

We can see from 1:
1. The security mode is WPA.
2: The password is 11111111"

Step 2: Modify the dictionary file to include the correct password "11111111" and the wrong password "22222222", as shown in Figure 2:

We can see from 2:
1: the correct password "11111111" and the wrong password "22222222" already exist, and some common passwords exist.

Step 3: capture packets and specify dictionary files, as shown in figure 3.

Step 4: Use the correct password "11111111" to connect to the wireless router used in the experiment, as shown in Figure 4 and 5.

4:
1: The handshake packet has been captured.

5:
1: The password is successfully found in the dictionary file.

Step 5: similar to the previous step, this time the wrong password "22222222" will be used to connect the experiment to a wireless router, as shown in figure 6, 7

We can see from 6:
1: The handshake packet has been captured.

7:
1: The password is successfully found in the dictionary file.

Lab report: A handshake packet is generated when the client uses the wrong password to connect to the wireless router. If the dictionary contains the wrong password, a wrong wireless access password is obtained.

Advanced knowledge: how to determine whether the captured handshake package contains the correct wireless access password?

The client uses the wrong password to connect to the wireless router. After four handshakes, the wireless router sends Deauthentication Packets to the client and rejects access from the client. See Figure 8:
