　　The victim is Brian Krebs (pictured above), an American journalist who often reports on internet criminals, including those who run DDoS-for-hire services, and also those involved in the “dark” markets that trade in stolen identities and credit-card details. In the past, some of the people he has annoyed have sent heroin to his home while alerting the police to the fact they might find the drug there. This time, the very internet itself was turned against him. On September 20th Mr Krebs’s web server became the target of one of the largest DDoS attacks ever recorded—between 600 billion and 700 billion bits per second, or almost half a percent of the internet’s entire capacity, for hours at a time.

　　一美国新闻记者Brian Krebs深受其害。Brian Krebs经常报道网络罪犯，包括曝光那些出租DDoS服务的人，盗窃身份和信用卡详情的黑市交易行为。过去，一部分被他惹恼的人曾给他家邮递海洛因之后报警，说警察可能会在他家找到毒品。他依靠网络曝光不法行为，而这次他恰恰栽在了网络身上。9月20日，Krebs的网络服务器受到了最大规模的DDoS攻击。在长达数小时的情况下，他服务器的访问量竟然达到了每秒六亿到七亿比特——相当于整个互联网可接受能力0.5%。

　　Entire：adj. 全部的，整个的

　　At first, his “network mitigation provider”, a firm called Akamai that was supplying its services to him free, for the general good of the field, was able to ward off these attacks. Eventually, though, it had to surrender. On September 23rd, with his agreement, it cut him loose and he had to shut down until he could make alternative arrangements.

　　起初他的“网络缓解系统供应商”，名叫阿卡迈的公司，出于这个领域的共同利益，给他免费提供服务。这些服务能够抵挡网络攻击。最后阿卡迈公司也撑不住了。9月23日，在征得他的同意后，阿卡迈公司关闭了对他的服务，找到其他方法之前，他不得停掉自己的网站。

　　Mitigation：n. 减轻;缓和;平静Provider：n. 供应者;养家者

　　Though Mr Krebs’s case is extreme by current standards, there is a risk it will soon become typical. Matthew Prince, the boss of CloudFlare, a firm that helps websites manage heavy traffic and deal with assaults of this sort, says his firm has already seen a sustained ten-day trillion-bits-per-second DDoS attack—though that was launched by a country (he declined to say which) rather than by a private criminal organisation. Other firms, such as OVH, a French web-hosting service, have also reported attacks of this magnitude.

　　尽管就目前的网络攻击标准来看，Krebs的例子比较极端、少见，但他这种情况很可能迅速地多起来。一家帮助网站管理繁重的访问量和处理此类攻击的公司CloudFlare的总裁Matthew Prince说，他的公司已经连续十天受到每秒万亿比特的DDoS攻击——虽然攻击来自某个政府(他拒绝透露是哪个国家)而非私人犯罪组织。其他公司比如法国一家网络主机服务公司OVH(Open Virtual Hosting)也被报道过遭受了同样严重的攻击。
