An organised attack on the servers of a domain registrar in China earlier this week caused an online video application to cripple internet access in parts of the country the Ministry of Industry and Information Technology said.This is the first time the regulator has published news about an investigation into an online attack in China within 24 hours.The DNS attack affected internet users in the Shanxi, Zhejiang, Jiangsu and Hebei provinces and Guangxi Zhuang Autonomous Region and meant they were unable to access the internet from 21.00 local time on Tuesday. Access returned to normal by 01.00 on Wednesday, the ministry said on its Website last night. Shanghai users were not affected.During the period of the DNS attack, “repeated requests poured into a DNS server called Baofeng.com, which surpassed the capacity of the server and paralysed it. The users of Baofeng.com also carried the requests, experts at China Telecom and Baofeng said, reported the Shanghai Daily.”The problems started when registrar DNSPod’s DNS servers were targeted with a DDOS (distributed denial of service) attack, described by the company in an online statement”, according to another report, this time from IDG. “In such an attack, the attacker orders a legion of compromised computers to try to communicate with a server all at once, which overwhelms the server and crushes its ability to return requests for information.”More information is available from:
