美國調查聯邦調查局和司法部網站遭襲

The FBI says it is investigating why the websites for the FBI, the Department of Justice, and several entertainment industry sites all went down Thursday after the government shut down one of the world's largest file-sharing sites.

The hackers' group calling itself "Anonymous" claimed credit for the attacks, which kept the sites offline for several hours late Thursday. By Friday, most had been restored to service, including the federal agencies.

Earlier Thursday, U.S. federal authorities shut down the file-sharing site known as Megaupload and charged its founder and six others with violating piracy laws.

Megaupload founder Kim Dotcom ((aka Kim Schmitz)) was arrested in New Zealand Thursday along with three other top executives at the request of U.S. authorities. Three others facing charges remain at large.

A statement by the U.S. Justice Department and FBI said the action is "among the largest criminal copyright cases" ever brought by the United States. If found guilty, the suspects face up to 20 years in prison. Authorities say Megaupload cost copyright holders more than $500 million.

Megaupload allowed users to upload and transfer very large files. Federal officials say the website used this ability to make copyrighted material, like Hollywood movies, available for free, often before the film was even released in theaters.

But the company, and many celebrity supporters, say the site was mainly used for legitimate file transfers.美國聯邦調查局說，正在調查聯邦調查局、美國司法部和一些娛樂業的網站星期四突然癱瘓的原因。

此前，美國政府關閉了世界上最大的一家文件分享網站。

一個自稱爲“匿名者”的黑客組織聲稱發動襲擊，這次襲擊讓有關網站星期四晚間脫機了幾個小時。

截至星期五，包括聯邦政府網站在內的多數網站已經恢復運行。

星期四早些時候，美國聯邦政府關閉了全球最大的文件共享網站之一MU網盤（Megaupload），該網站的創始人和另外六人受到觸犯盜版法的指控。

在美國政府的要求下，MU網盤（Megaupload）公司創始人金·道康（金·史密茨）和另外三名高層主管1月19日星期四在新西蘭被逮捕。其他三名受到指控的人還沒有被緝拿歸案。

美國司法部和聯邦調查局發表的一份聲明說，這是美國政府有史以來“針對版權犯罪行爲的最大案例之一”。嫌疑人如果被判有罪，將面臨最高爲20年的監禁。當局說，MU網盤導致版權所有者損失了超過5億美元。

MU網盤允許使用者上載和傳輸容量很大的文件。聯邦官員說，這個網站讓好萊塢影片等受到版權保護的內容可以免費獲得，而且經常是在影片在電影院公映之前。

但是，這家公司以及許多支持它的社會名人說，這個網站主要用於合法文件的傳輸。
