China Hackers Got Data Going Back to '85

A massive data breach in December affected the federal human-resources department that issues security clearances and holds employee records, compromising personal information from at least 4 million current and former employees going as far back as 1985. "That could give them a huge advantage," an anonymous U.S. official said. The Washington Post reports it was Chinese hackers who targeted the Office of Personnel Management and the Interior Department. “We take all potential threats to public- and private-sector systems seriously and will continue to investigate and hold accountable those who pose a threat in cyberspace,” the FBI said in a statement Thursday night.
