Congressman Says China Waging Long-Term Cyber Espionage

The Chinese government is developing detailed profiles of U.S. workers and private citizens as part of a long-term strategic espionage campaign that might include blackmailing key government officials, said the chairman of the House Homeland Security Committee.

The theft of data on as many as four million government workers disclosed last week was done by the same Chinese hackers who stole tens of millions of health-care records in recent attacks on Anthem Inc. and Premera Blue Cross, said Representative Michael McCaul, a Texas Republican.
