前言

最近在学校内网瞎搞，就有了这个脚本，一个用来爆破用户名，另一个用来爆破默认密码。

验证码识别用的是腾讯云的OCR，不过也可以手动打码。

脚本

安装依赖： pip install requests bs4 lxml

爆破用户名

存在的用户名会保存在 users.txt 里

爆破默认密码

@> 登陆错误50次就锁IP了，所以手动打码也完全没有问题。

用户名文件为 users.txt，结果保存在 result.txt

PS:因为测试了几个账号,都没有修改默认密码,加上每小时只能试50条的限制,这个脚本没有真正使用过,不过功能是正常的。

执行效果

配合第二个脚本就可以快速筛选出使用默认密码的账号了
