FBI查封13个与 DDoS 攻击服务相关的互联网域名



美国司法部近日宣布了针对攻击者的电脑服务清理计划中的第三轮行动,共查获了13个与DDoS租用服务有关的域名,并以法庭许可为基础实施了查封行动。这些网站允许支付用户进行DDoS攻击,致使目标计算机信息泛滥,并难以连接到因特网。

调查数据显示,数十万注册用户已经使用这些服务发起了数百万次攻击,针对的受害者包括学区、大学、金融机构和政府网站等等。尽管之前已经针对一些租用服务进行过打击,但此次行动也反映了打击不法行为的决心。


此次FBI用加密货币测试了这些站点,并用这些租用服务对他们自己的计算机进行了DDoS攻击的模拟实验。调查表明,这些攻击不仅会干扰和破坏受害者的网络连接,也会让与同一网络交通里存在共享连接点的其他客户网络连接中断。四名被判有罪的相关责任人将于今年夏天受到判决。

DDoS攻击是一种分布式拒绝服务攻击,攻击者通过利用众多计算机向目标服务器发送请求,从而导致目标服务器崩溃或失去响应能力。此类攻击具有匿名性和低门槛,成本较低,很容易被攻击者忽视和低估。所以,加强网络安全防范已成为互联网时代的重要任务之一。


DDoS攻击是一种典型的网络攻击方式,其威胁不仅限于攻击目标,还可能对部分互联网基础设施和服务造成影响,对整个互联网产生连锁反应,造成影响的规模和范围难以预料。目前流行的DDoS攻击工具主要包括公开的黑客工具、收费的攻击服务、僵尸网络和大量计算机感染了恶意软件之后形成的网络木马等。


针对DDoS攻击的防御措施包括物理层和网络层、域名系统安全加强和云防御等多个方面。可以使用专业的防火墙设备、反向代理、负载均衡等网络设备进行物理层和网络层防御。而云防御可以有效地抵御DDoS攻击,通过将目标服务器接入专业的防御平台保障网络的安全稳定。
