互联网遭02年以来最严重黑客袭击

北京时间2月7日消息 据国外媒体最新报道，黑客已经制服了管理全球电脑网络通信的13台根服务器中的至少3台，这是继2002年以来最严重的互联网黑客袭击。

有专家称这起非同一般的攻击事件仅持续了几个小时就感染了大量无防备的电脑用户，全世界的电脑专家正忙于应付有渗透入网络致命通道危险的大量数据。专家认为黑客在有意识地隐藏身份，但是大量的资料数据指向了韩国。

此次攻击对象为运营以“org”及一些其他后缀结尾的网址服务器的UltraDNS公司，该公司并未立即公开对此做出回应。

互联网名称与数字地址分配机构ICANN首席技术官约翰·克雷恩（John Crain）表示，在美国加州显示为此次攻击从周二夜晚开始持续到早晨，攻击仍在进行，调查也仍在进行中。他还表示，此次袭击造成的后果没有2002年10月黑客袭击这13台根服务器时那样严重，因为近年来的技术革新已将根服务器工作量渐渐分散至全球的其他服务器。

Hackers attack Net traffic computers(AP)Updated: 2007-02-07 07:28
Hackers briefly overwhelmed at least three of the 13 computers that help manage global computer traffic Tuesday in one of the most significant attacks against the Internet since 2002.
Experts said the unusually powerful attacks lasted as long as 12 hours but passed largely unnoticed by most computer users, a testament to the resiliency of the Internet. Behind the scenes, computer scientists worldwide raced to cope with enormous volumes of data that threatened to saturate some of the Internet's most vital pipelines.
The motive for the attacks was unclear, said Duane Wessels, a researcher at the Cooperative Association for Internet Data Analysis at the San Diego Supercomputing Center. "Maybe to show off or just be disruptive; it doesn't seem to be extortion or anything like that," Wessels said.
Other experts said the hackers appeared to disguise their origin, but vast amounts of rogue data in the attacks were traced to South Korea.
The attacks appeared to target UltraDNS, the company that operates servers managing traffic for Web sites ending in "org" and some other suffixes, experts said. Officials with NeuStar Inc., which owns UltraDNS, confirmed only that it had observed an unusual increase in traffic.
Among the targeted "root" servers that manage global Internet traffic were ones operated by the Defense Department and the Internet's primary oversight body.
"There was what appears to be some form of attack during the night hours here in California and into the morning," said John Crain, chief technical officer for the Internet Corporation for Assigned Names and Numbers. He said the attack was continuing and so was the hunt for its origin.
"I don't think anybody has the full picture," Crain said. "We're looking at the data."
Crain said Tuesday's attack was less serious than attacks against the same 13 "root" servers in October 2002 because technology innovations in recent years have increasingly distributed their workloads to other computers around the globe.
