The Social Security Administration’s chief data officer, Charles Borges, has filed a whistle-blower complaint alleging that members of the Department of Government Efficiency copied the agency’s Numerical Identification System database—holding roughly 450 million Social Security records—to an Amazon-hosted cloud server in June. Borges contends the environment lacked independent security controls and monitoring, creating what he called “enormous vulnerabilities” for the personal information of nearly every living and deceased holder of a U.S. Social Security number. Internal memos cited in the complaint show SSA chief information officer Aram Moghaddassi and senior DOGE official Michael Russo approved the transfer in less than 30 minutes, overriding warnings that the project was “high risk.” The move followed a 6 June Supreme Court decision that lifted a lower-court order blocking DOGE’s access to Social Security data. Borges says the setup left only DOGE personnel with administrative rights, bypassing normal SSA cybersecurity oversight and potentially violating federal privacy laws. The SSA said it is not aware of any compromise and maintains that the data are stored in a long-standing, internet-walled environment overseen by its security team. The Office of Special Counsel has 45 days to review the complaint, which could trigger a formal investigation. DOGE, an efficiency unit created by President Donald Trump and initially run by Elon Musk, faces mounting scrutiny from lawmakers who warn that a breach could force the government to reissue Social Security numbers and disrupt benefits for millions of Americans.
