The website of prominent security blogger Brian Krebs is back online this week after sustaining one of the largest distributed denial of service attacks in Internet history.
DDoS attacks typically disrupt service at a website by flooding it with junk traffic. In this case, garbage traffic assaulted Krebs' site at 620 gigabits per second. By comparison, consumer bandwidth is in the 10-15 megabit per second range; businesses, 100 Mbps to 1 Gbps.
The attack may have been even larger than reported so far, maintained Matthew Prince, CEO of Cloudflare.
"There was evidence that a lot of the upstream providers were getting congested and dropping packets upstream," he told TechNewsWorld.
When that's taken into account, "this attack could have been close to a terabit attack," Prince said.
Akamai's Exit
The attack was so large that Akamai, the company that had been protecting Krebs' site from DDoS attacks for years, had to withdraw its support from the blogger.
"Let me be clear: I do not fault Akamai for their decision," Krebs wrote in a Sunday post.
