Last night, I wrote a Python code to break the wifi password of my sister next door


Last night, my family stopped the Internet. For Minoan, the Internet stopped. Can you bear it? Call to repair the network, said it's too late, it will take the next day to come over


Many people study python and don't know where to start.
Many people learn python, master the basic syntax, do not know where to find cases to start.
Many people who have already done cases do not know how to learn more advanced knowledge.
Then for these three types of people, I will provide you with a good learning platform, free access to video tutorials, e-books, and the source code of the course!

All of a sudden, I found that the wifi signal of the next sister's paper was full. Wow, it made me have a bad idea to see if there was any way to get off the net. First of all, I used the universal key. It didn't work~~~


Then I can only use the dictionary to run the password. This small function must be completed by python. After searching, I found that the pywifi component just meets the requirements.


Let's record my operation.



Python's rich third-party libraries naturally include wifi API s, which can be easily connected. If you have a detailed codebook, you can realize the violent cracking of wifi password, provided you have enough patience and time to wait.




For the given wifi name, we use the password repeatedly to try one by one. If it fails, we will disconnect until the connection is successful.


That is to say, import the required third-party library (please download and install it yourself), call the network card interface through pywifi, test in turn, and try to connect by reading the password circularly. Here you only need to change the password file path and wifi name.


#Environmental preparation


  • python2.7
  • pywifi module
  • Dictionaries


#Import module

from pywifi import *


#Dictionary preparation


Random wifi weak password top 10. One line contains only one set of passwords, and the script reads each line in turn until the correct password is found.
