Hackers broke into the U.S. Library of Congress government affairs Web site yesterday and altered it with their own text, federal officials confirmed today.
The hackers changed the site to read, "U.S. Congress Web site -- defeated!"
Helen Dalrymple, a public affairs specialist for the Library of Congress, which administers the site, said today.
The group identified itself on the site as the "Lamers Team," and said they were "four hackers from a little country in Europe," Dalrymple said. She declined further comment.
The site, called "Thomas," offers information on Congressional activities, including the status of Legislation, the Congressional Record and committee news.
In a brief statement released this afternoon, the Library of Congress estimated the Thomas home page was defaced for about 90 minutes, starting at 6 p.m. yesterday. Staffers discovered the problem at about 7 p.m. and blocked Internet access to the Thomas system at about 7:20 p.m.
The site's network and computer security system is under review and the incident is being investigated, the statement said.
The attack was the latest of several against government Web sites. Vandals have altered Web sites of the White House, the U.S. Federal Bureau of Investigation, the U.S. Senate and the U.S. Army.
