2002 年一月11 日凌晨两点，grc.com 被一些更先进的恶意洪水数据包攻击。这种新型的DDoS 攻击可以被成为分布式反射拒绝服务攻击（Distributed Reflection Denial of Servie Attack ）― DRDoS 神秘的洪水攻击攻击在凌晨两点左右开始，那时我正好还在工作，所以我才有机会迅速的抓取到一部分的洪水攻击的信息。这次攻击使Verio（我们的网络提供商）的集合路由器将攻击数据挤满了我们的两条T1。我们的网站服务器因为这次攻击而无法处理其它合法的请求。我们被完全的炸下了网。
我们以前就曾遭受过UDP 和ICMP 洪水攻击，这些攻击其实都可以由被攻击者入侵的主机、zombie 工具及Windows 系统简单的实现，我们也被一些经典的SYN 洪水攻击过。所以当我查看了一下那些显示我们是被SYN/ACK 数据攻击的攻击数据包后，眉毛跳了一下。毕竟这些事实并不重要，就像我以前说的那样，一个SYN/ACK 包只是一个SYN 数据包带了一个ACK标记。任何有限权制作"raw socket"的人都可以制作出这种数据包来―― 不管他是恶意的还是无意的。
真正的惊讶是当我看到这些发起攻击的地址：
