Iran hacks opposition Web sites, arrests cyber activists

Iran's Islamic Revolutionary Guards Corps hacked into 29 Web sites affiliated with U.S. espionage networks, Iran's semi-official Fars News Agency reported on Sunday.

"The hacked websites acted against Iran's national security under the cover of human rights activities," Fars reported. It did not disclose details of the attacks. The 29 Web sites were identified in a statement (in Farsi) released on a Web site operated by the Revolutionary Guards. The Internet has been used by Iranian opposition groups who contested the results of last year's elections there to organize demonstrations and share information about protests and arrests. The Revolutionary Guards is a military group that was founded after Iran's 1979 revolution. The group includes conventional army, navy, air force, and intelligence units, as well as the Basij paramilitary force and various business units.
