Linux主机简单判断被CC攻击的网站命令-比较直接有效

香港云服务器

CC攻击很容易发起,并且几乎不需要成本,导致现在的CC攻击越来越多。
大部分搞CC攻击的人,都是用在网上下载的工具,这些工具很少去伪造特征,所以会留下一些痕迹。
使用下面的命令,可以分析下是否在被CC攻击。

第一条命令

正常的输出结果类似于这样
POST /ajax/validator.php HTTP/1.1
POST /api_redirect.php HTTP/1.1
GET /team/57085.html HTTP/1.1
POST /order/pay.php HTTP/1.1
GET /static/goodsimg/20140324/1_47.jpg HTTP/1.1
GET /static/theme/qq/css/index.css HTTP/1.1
GET /static/js/index.js HTTP/1.1
GET /static/js/customize.js HTTP/1.1
GET /ajax/loginjs.php?type=topbar& HTTP/1.1
GET /static/js/jquery.js HTTP/1.1
GET /ajax/load_team_time.php?team_id=57085 HTTP/1.1
GET /static/theme/qq/css/index.css HTTP/1.1
GET /static/js/lazyload/jquery.lazyload.min.js HTTP/1.1
GET /static/js/MSIE.PNG.js HTTP/1.1
GET /static/js/index.js HTTP/1.1
GET /static/js/customize.js HTTP/1.1
GET /ajax/loginjs.php?type=topbar& HTTP/1.1
GET /static/theme/qq/css/i/logo.jpg HTTP/1.1
GET /static/theme/qq/css/i/logos.png HTTP/1.1
GET /static/theme/qq/css/i/hot.gif HTTP/1.1
GET /static/theme/qq/css/i/brand.gif HTTP/1.1
GET /static/theme/qq/css/i/new.gif HTTP/1.1
GET /static/js/jquery.js HTTP/1.1
GET /static/theme/qq/css/i/logo.jpg HTTP/1.1
正常命令结果以静态文件为主,比如css,js,各种图片。
如果是被攻击,会出现大量固定的地址,比如攻击的是首页,会有大量的“GET / HTTP/1.1”,或者有一定特征的地址,比如攻击的如果是discuz论坛,那么可能会出现大量的“/thread-随机数字-1-1.html”这样的地址。

这个是查看客户端的useragent,正常的结果中,是各种各样的useragent。
大多数攻击使用的是固定的useragent,也就是会看到同一个useragent在刷屏。随机的useragent只见过一次,但是给搞成了类似于这样“axd5m8usy”,还是可以分辨出来。
