我认为:无论是学习安全还是从事安全的人,多多少少都有些许的情怀和使命感!!!

一句话密码的穷举

1、cheetah.py脚本穷举

(1)代码,如下所示:

#!/usr/bin/env python
# -*- coding: utf-8 -*-

""" Cheetah is a dictionary-based webshell password violent cracker that runs like a cheetah hunt for prey as swift and violent. Cheetah's working principle is that it can submit a large number of detection passwords based on different web services at once, blasting efficiency is thousands of times other common webshell password violent crack tools.

if __name__ == '__main__':
    main()

(2)语法:

python cheetah.py -u http://orz/orz.php
    python cheetah.py -u http://orz/orz.jsp -r post -n 1000 -v
    python cheetah.py -u http://orz/orz.asp -r get -c -p data/pwd.list
    python cheetah.py -u http://orz/orz -w aspx -s iis -n 1000
    python cheetah.py -b data/url.list -c -p pwd1.list pwd2.list -v

(3)示例:

php一句话:

cheetah.py -u http://www.yijuhua.com/a.php -n 1000 -v -p data/pwd.list img

asp一句话:

cheetah.py -u http://www.yijuhua.com/a.asp -n 1000 -v -p data/pwd.list img

aspx一句话:

cheetah.py -u http://www.yijuhua.com/a.aspx -n 1000 -v -p data/pwd.list img

img

2、尝试利用一句话

(1)php一句话的利用: img
