Ruthanne Reid A distributed denial-of-service attack targeting a client of the content delivery network Cloudflare reached new highs in malicious traffic today , striking at the company’s data centers in Europe and the US. According to a Twitter post by Cloudflare CEO Matthew Prince, the full volume of the attack exceeded 400 gigabits per second—making it the largest DDoS attack ever recorded. The attack used Network Time Protocol (NTP) reflection , the same technique used in recent attacks against gaming sites by a group called DERP Trolling. NTP is used to synchronize the time settings on computers across the Internet. The attack made fraudulent synchronization requests to NTP servers that caused them to send a flood of replies back at the targeted sites. Reflection attacks have been a mainstay of DDoS tools and botnets, but the use of NTP in such attacks is relatively new. Last year’s attack on Spamhaus , which previously set the record for the largest DDoS ever, used a Domain Name Service (DNS) protocol attack—a much more common approach that takes advantage of the Internet’s directory service, forging requests for DNS lookups from the intended target and sending them to scores of open DNS servers. The size of the traffic directed back at the target from these requests far exceeds the size of the requests sent to the DNS servers, which is why the technique is often called a DNS amplification attack.

Biggest DDoS ever aimed at Cloudflare’s content delivery network
Amazon has just reported its earnings for the fourth quarter of 2013 . According to The Verge , Amazon CFO Tom Szkutak mentioned that the company is considering a price increase for its Amazon Prime customers in the US. The decision hasn’t been made, but high shipping costs could prompt a price increase of between $20 and $40 a year for the service. Prime began life as a service that offered free two-day shipping on many items for a flat, $79-a-year fee. As Amazon has branched out into tablets and streaming media, perks like the Instant Video service and Kindle Owners’ Lending Library have been added to sweeten the deal. The potential price increase would be the first since Prime was introduced in the US in 2005. Amazon reported income of $239 million on sales of $25.59 billion for the fourth quarter of 2013, lower than analysts had expected. The company’s guidance for the first quarter of 2014 projects sales between $18.2 and $19.9 billion and expects income to be somewhere between a profit of $200 million and a loss of $200 million.
