China suffers major DDoS attack on .cn domain

It's still unclear where the DDoS attack originated from

China's Internet on early Sunday morning suffered a major distributed denial of service (DDoS) attack that briefly disrupted and slowed access to sites in the .cn domain.

The DDoS attack was the largest in history against the domain servers for China's .cn ccTLD (country code top level domain), according to the China Internet Network Information Center (CNNIC), which administers the domain.

The first attack started Sunday around midnight Beijing time, and was then succeeded by a larger attack at 4 a.m, the CNNIC said in an Internet posting. A number of sites were affected, but Internet service to the sites had been gradually restored by 10 a.m. Sunday

It's unclear where the attack originated from or if it was still continuing. A CNNIC spokeswoman said on Monday it would update the public once more information was gathered. Chinese regulators have already launched unspecified measures to protect the domain system, while CNNIC has apologized for the disruption.

China has often been accused of launching DDoS attacks. In this year's first quarter, it was the top source country for DDoS attacks, according to security vendor Prolexic. The U.S. was ranked second.

DDoS attacks can commonly work by deploying armies of hacked computers to send traffic to a website, saturating it with data so that it becomes inaccessible to normal users.

China, however, has said its facing a surge of Trojan and botnet attacks against the country. Many of those attacks are coming from the U.S., South Korea and Germany. China has also denied the country sponsors hacking, despite claims brought by U.S. officials and security vendor Mandiant that its government actively conducts cyber-espionage.

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.
