The group also claimed responsibility for a sophisticated attack on Harvard University's home page last year that briefly defaced the page with a message accusing the U.S. of supporting the uprising against Syria's president.
Pro-Syrian government hackers have stepped up their attacks on news agencies in recent weeks. In early August, Reuters suffered two security breaches in two days when hackers managed to gain control of one of its Twitter accounts and defaced with pro-Syrian government tweets. Earlier that week, hackers broke in to the Reuters.com Web site and added a phony post purporting to be an interview with the head of the Free Syrian Army.
