Officials: Second hack exposed military and intel data

Hackers linked to China have gained access to the sensitive background information submitted by intelligence and military personnel for security clearances, U.S. officials said Friday, describing a cyberbreach of federal records dramatically worse than first acknowledged.

The forms authorities believed may have been stolen en masse, known as Standard Form 86, require applicants to fill out deeply personal information about mental illnesses, drug and alcohol use, past arrests and bankruptcies. They also require the listing of contacts and relatives, potentially exposing any foreign relatives of U.S. intelligence employees to coercion. Both the applicant's Social Security number and that of his or her cohabitant is required.
