CC攻击其实属于DDoS攻击的一种，这种攻击普遍都是流量不是很高，但是破坏性非常大，直接导致系统服务挂了无法正常服务。评长期处于防护状态经验的我来说可以分为以下几种类型：

1、SYN-CC攻击；这种比较常见，直接使用高并发来请求目标导致目标网站或应用无法提供正常服务。防护无非就是常规的并发限制，一般的硬防都可以过滤这些常规的CC攻击。如下图：

2、POST流量耗用型；这种是利用目的地址不限制动态请求，恶意提交数据交互导致服务中断，常规的这种带宽耗用都很高，如果不是弹性带宽还真会长时间被耗用完cpu、内存、带宽资源。还有更恐怖让用户看傻眼的是，网站注册短信接口被post恶意请求导致几秒钟消耗完几千元的短信费用，目前在这个攻击中这种受影响的网站占比非常大，曾经有几个朋友都是因为这个事情找我帮他们彻底解决了。

这里不得不说小编的朋友无笔秀才了，他们短信接口余额2000多在几秒内直接消耗完，开始他们购买了XX云的waf防火墙，后发现还是屏蔽不完，重新充值的费用又在几分钟内消耗完，后找到墨者安全，通过墨者技术人员分析后发现waf过滤只过滤了60%左右的恶意请求，效果一般，即刻就给他上了墨者新开发的指纹识别防护就稳定下来了，连续几天恶意请求都非常多直接进黑名单，让再无法消耗接口费用了。

3、模拟UA以及常规的百度伪装；这种攻击也算常规伪装了，非常多，毕竟国内百度爬虫多。目测只要有网站攻击，就一定会出现伪装百度的CC攻击。

4、浏览器漏洞CC请求攻击；利用浏览器漏洞控制浏览器来发动攻击，请求真实的地址，这种可以说是目前难防护的攻击，目前没有人能百分百说能搞定这个攻击，不过有这个实力的人非常少，所以目前还不用担心。这么多年来，我接触过这种类型的攻击，都需要定制化解决，也总共遇到过2次这种攻击，也很完美解决了，因为这个访问确实都是正常访问，与其他的不同就是他不是伪装，是真实请求。

5、疯狂代理型超多肉鸡IP请求型；网上好多代理网站，购买这些代理IP来发动恶意的请求，做代理的估计有一半是被人购买去搞CC攻击（个人猜测，不喜勿喷）。

6、路由盒子劫持攻击；这种攻击也比较难预防，请求也是合法的请求，而且路由盒子量非常庞大，曾经网上遇到有人说能控制几百万路由盒子，那恐怖，我听了都怕。不过这种如果有人敢攻击，应该有背景吧，或者是年轻不考虑后果型的。

7、其他变态类；其他综合起来一起来评价，一般都是网上很多版本各式各样的攻击器模拟出来的，世界无限大，什么都有。

当我们发现网站遭到CC攻击的时候不要过度惊慌失措，先查看一下网站服务器是不是被黑了，找出网站存在的，然后做好网站的安全防御，开启IP禁PING，可以防止被扫描，关闭不需要的端口。通过墨者盾高防对访问者的URL，频率、行为等多重画像访问特征进行分析，智能识别CC攻击并进行拦截，保障网站正常稳定运行。
