Hackers steal millions of US military personnel records
The U.S. government is alerting millions of current and former military personnel that their personal information, including Social Security numbers and service records, was stolen in a months-long breach of the Pentagon's Defense Manpower Data Center (DMDC). The breach exploited a file-sharing vulnerability between October 2025 and mid-July 2026, affecting about 2.8 million living people and nearly 300,000 deceased. The data was unencrypted. The Department of Defense found no evidence of misuse yet. This follows a similar breach at the FBI attributed to ShinyHunters, raising concerns about national security risks.
