A huge portion of Chinese-based Internet was disrupted on Sunday courtesy of a massive distributed denial of service (DDoS) attack. The government has said it was the biggest it had ever experienced, as the attack was designed to flood networking infrastructure at the China Internet Network Information Center, which manages the Chinese domain name system and the .cn top level domain.
One such attack hit on Sunday morning at 2am, with another more powerful DDoS arriving within the space of two hours. It is thought a numbered of sites went down, whilst others experienced a slow or interrupted internet access. The attack appeared to have been overcome by Monday and security experts have spotted lots of signals which are out of the ordinary, hinting at a significant DDoS in China. Dan Holden, director of research at Arbor Networks, said “Arbor saw a significant increase in DDoS attacks targeting .cn on Sunday…The number of attacks more than doubled and ATLAS traffic statistics show a significant increase in attack size, indicating a serious attack was carried out.”
CEO Matthew Prince of content delivery network, CloudFlare told the Wall Street Journal it had seen a 32 percent dip in traffic for Chinese sites sitting on its CDN when compared to the same period a day before. “I don’t know how big the ‘pipes’ of .cn are, but it is not necessarily correct to infer that the attacker in this case had a significant amount of technical sophistication or resources,” adding that it could have been an individual rather than a group that carried out the attack. There have been a number of significant DDoS attacks of late, with suggestions of political motivations as China is home to a lot of DDoS activity. Akamai recently claimed the country saw 34 percent of global DDoS traffic in fourth quarter of 2012. Hosting provider GreenNet, which describes itself as an ethical host and ISP, with Fair Trade Africa and Privacy International amongst its customers, was knocked offline by significant DDoS strikes earlier this month.
