Pentagon Confirms Massive Data Breach: Hackers Steal Millions of U.S. Troops' Records

The U.S. Department of Defense has begun notifying millions of current and former military personnel that their personal information was stolen in a data breach that went undetected for months, according to a disclosure reported by TechCrunch. The compromised records belong to service members across multiple branches, though the department has not yet publicly detailed the full scope of the data taken or the identity of the attackers.

The breach is among the largest known compromises of U.S. military personnel data, affecting millions of individuals who served or are currently serving. Officials have not released specific figures on how many records were accessed or what categories of personal information were exposed, such as Social Security numbers, addresses, or health data. The department is expected to provide affected personnel with guidance on identity protection and monitoring services.

The incident raises serious questions about the security posture of government systems holding sensitive military data and could prompt congressional scrutiny, given the prolonged period during which attackers operated undetected. Affected personnel and veterans are advised to watch for phishing attempts and identity theft, while cybersecurity experts call for a full forensic review and stronger safeguards across defense networks.
