Gov't Personnel Hacking Called Threat to U.S. Spies Abroad

The breach of U.S. security clearance information in the cyber-hacking of the federal government's personnel office poses a "significant counterintelligence threat" and could compromise the identities of American spies abroad, senior U.S. officials said. Testifying before a U.S. House of Representatives panel, Director of National Intelligence James Clapper said there were no signs yet of any "nefarious" use of data accessed in the hacking of the Office of Personnel Management, which was disclosed in June.
