nginx过滤无聊的pingback CC请求

admin

1. if ($http_user_agent ~* (ApacheBench|pingback|WordPress|MJ12bot|AhrefsBot|360JK|PHP|php|Jorgee) ) {return 101;}
   
2. if ($http_user_agent = "" ) {return 101;}
   
3. if ( $request = "POST /reg.html HTTP/1.1" ) {return 400;}
   
4. if ( $request = "POST / HTTP/1.1" ) {return 400;}
   
5. if ( $request = "POST / HTTP/1.0" ) {return 400;}
   
6. if ( $request = "POST // HTTP/1.0" ) {return 400;}

nginx判断agent直接过滤掉一些低能的CC请求， 在这儿直接当个干货贴出来。

也让某些人以为拿小鸡鸡插进土里就**了地球的想法破灭。


代码实例加入nginx后重载或者重启，可以自己拿wordpress的pingback漏洞给自己测试一下，查看日志101状态的记录则是已经被拦截的。


状态码101也可以改成400，自己随意了。


类似低能的CC不用正眼看一下，老有人打打小白觉得好厉害得不行。
