Per the Office of Personnel Management, retirement and payroll data were not compromised but "sensitive" background check records including Social Security numbers, financial histories, mental health records, fingerprints, and "information about immediate family and personal and business acquaintances." It is "highly likely" that anyone who has undergone a background check since 2000 has been impacted. Since background reinvestigations are conducted "a minimum of every 5 years for a Top Secret level clearance and every 10 years for a Secret level clearance," confidential data on the vast majority of people with active security clearances has been exposed.
