The Social Security Administration’s chief data officer, Charles Borges, has filed a whistle-blower complaint alleging that staff from the Department of Government Efficiency created a live copy of the agency’s NUMIDENT database—containing the personal records of every Social Security number ever issued—and uploaded it to an Amazon cloud environment in June. The filing, dated Aug. 26, says the cloud system lacks independent security controls or audit mechanisms, putting the identities and federal benefits of more than 300 million Americans at risk. According to the complaint, SSA Chief Information Officer Aram Moghaddassi, a former executive at Elon Musk-led firms, approved the transfer on July 15, writing that the business need outweighed security concerns and that he would “accept all risks.” Borges contends the move violates the Federal Information Security Modernization Act and internal SSA policies, warning that a breach could force the government to re-issue Social Security numbers nationwide and disrupt health-care and nutrition benefits. DOGE’s access to the data followed a Supreme Court ruling in June that overturned a lower-court injunction blocking the department from tapping SSA systems. Labor and retiree groups had sued earlier this year to halt the arrangement. The complaint also alleges DOGE personnel regained access to sensitive databases even during the court-ordered suspension, and that earlier risk assessments labeled the cloud copy “high-risk” with “catastrophic” potential impact. An SSA spokesperson said the agency “takes all whistle-blower complaints seriously,” insisting the data is stored in a long-standing environment walled off from the internet and that the agency is unaware of any compromise. Sen. Ron Wyden, the top Democrat on the Senate Finance Committee, called DOGE’s handling of the records “reckless” and urged congressional investigations. The Office of Special Counsel has 45 days to determine whether to open a formal probe.
