Internet core infrastructure hit in rare cyber-attack

 
Unknown parties carried out a large-scale DDoS attack on the Internet's DNS root servers, causing slight timeouts for four nodes, more exactly on the B, C, G, and H servers, RootOps reports.
 
There were two different attacks, one launched on November 30 that lasted 160 minutes (from 06:50 to 09:30 UTC), and a second, shorter one on December 1 that lasted only one hour (from 05:10 to 06:10 UTC).
 
RootOps, the DNS root server operators, are reporting that the attacks were valid DNS queries addressed towards one domain in the first attack, and to a different domain on the second day.

Target appears to have been two Chinese domain names

The internet's root servers were not the target of a distributed denial-of-service (DDoS) attack in December which for a short time took out four of the 13 pillars of the global network.
 
That's according to two security researchers who will present their findings at a conference in Argentina on Friday. Instead, they conclude the likely target of the massive assault was two seemingly obscure domain names registered in China.
 
Matt Weinberg and Duane Wessels work as DNS specialists for Verisign, the US company that operates two root servers and also approves changes to the internet root zone. Weinberg and Wessels carried out an extensive investigation into the flood of junk traffic that most root servers received on 30 November and 1 December 2015. A copy of their presentation [pptx] is now available online.
