US personnel office: More than 25 million records affected by hacking

The U.S. Office of Personnel Management said on Thursday that hackers had stolen sensitive information, including Social Security numbers, of about 21.5 million people from background investigation databases. The 21.5 million included 19.7 million individuals who applied for security clearances, plus 1.8 million nonapplicants, including mostly spouses or cohabitants of applicants, OPM said. The 21.5 million affected is in addition to information about 4.2 million current and former federal workers stolen in a “separate but related” incident. There is significant overlap between the two groups.
