Online Security, a global provider of computer forensics and information technology risk mitigation since 1997   Original Source:    http://www.informationweek.com/story/showArticle.jhtml;jsessionid=MDSTRH0UZSHREQSNDBCCKHQ?articleID=26806122 Cyberattacks Disrupt Japanese Government Networks By The Associated Press Aug. 5, 2004 TOKYO (AP) -- A wave of cyberattacks disrupted Japanese government computer networks earlier this week, but no damage was reported, an official said Thursday. The attacks, late Sunday and early Tuesday, targeted eight ministries and agencies and caused computers to freeze up under a deluge of data, Chief Cabinet Secretary Hiroyuki Hosoda told a news conference. Hosoda said the barrage also made it impossible for anybody to access Web sites for the eight government bodies--the Cabinet Office, Foreign Ministry, Finance Ministry, Justice Ministry, National Police Agency, Defense Agency, Coast Guard, and Fair Trade Commission He said there was no significant damage and that the networks had resumed normal operations. However, he added that it's nearly impossible to track the data. "We don't know where the attack came from, or who did it," he said. In January, several ministries suffered a similar, small-scale cyberattack, temporarily freezing Web servers but causing no permanent damage. So-called denial-of-service--or DoS--attacks bombard a Web server with so much data that the machine becomes unusable.
