During the weekend China’s Internet was taken down by a powerful DDoS attack, according to security experts behind the offensive there is a group of skilled hackers that on Sunday hit the country networks. But security expert clarified that China could have been perpetrated by sophisticated hackers or by a single individual. The China Internet Network Information Center [CINIC] reported that the attack began at 02:00 local time on Sunday with a peek at 04:00 that made it the largest DDoS attack the country’s networks have ever faced. CloudFlare security service provider revealed to have observed a 32 per cent drop in traffic for thousands of “.cn” websites compared with the same period in the preceding 24 hours.

The China Internet Network Information Center confirmed the attack with an official statement informing internet users that it is gradually restoring web services and that will operate to improve the security level of the Internet infrastructure of the country to prevent and mitigate further attacks.

Prince’s affirmation is reinforced by the possibility to retrieve on the underground market a huge quantity of DIY DDoS hacking tools that could allow the arrangement of a DDoS attack, it must be considered also the possibility to rent a botnet to hit a specific target for a limited period, both options accessible practically also to single individuals and small gangs.

Ironically, China is considered by analysts as the principal origin for this type of attack as revealed by many reports: such as the one published by Akamai security firm (“State of The Internet” report).
