Here is a reason why that person might have left:
In August 2025, a whistleblower from the Social Security Administration (SSA) alleged that a team from the Department of Government Efficiency (DOGE) created an unsecure copy of the agency's Numerical Identification System (NUMIDENT) database.
What data was involved? The NUMIDENT database contains Social Security numbers (SSNs), names, dates of birth, and other sensitive information for more than 300 million Americans.
What was the alleged security risk? The whistleblower claimed that DOGE copied the data to a cloud environment that lacked independent security monitoring and oversight, creating significant vulnerabilities.
What did the SSA say? The SSA denied any breach and stated that the data was kept in a secure, long-standing environment "walled off from the internet".
Is there evidence of a breach? No public evidence of a data breach has emerged from this incident, but the claim is that the data was made vulnerable to a potential attack.
