Pentagon and FBI data leaks: Security breaches of US systems

60 million people in the database

The leak from the database of the Ministry of Defense Employees Data Center (DMDC) affects 2.76 million living people and 294,000. dead. The intercepted data includes, among others: social security number (equivalent to the PESEL number in Poland) and details of the positions held by military and civilian personnel. According to the ministry's representative, this may raise concerns about national security.

"Between October 2025 and July 2026, a small number of unauthorized users gained access to personal information in the DMDC information system. After detecting the incident, DMDC immediately remedied the security vulnerability," a Pentagon representative told ABC News. He added that so far no evidence has been found of illegal use of the seized data. The victims were offered assistance in protecting their identity and monitoring their credit history.

DMDC is one of the Pentagon's main personal databases, storing personal files of over 60 million people - active-duty soldiers, reservists, civilian military employees, retired military personnel and their families.

Attack on the FBI recruitment website

A few days ago, the Federal Bureau of Investigation (FBI) reported a breach of employee data security. Hackers gained access to the classified recruitment portal FBIJobs.gov. However, in a statement sent to the media on Monday, the ShinyHunters hacker group declared that it would not publish the stolen data.

"(...) This is NOT extortion, it is NOT about ransom and it is NOT about money. It was a marketing campaign aimed at protecting our interests and actively fighting disinformation," the hackers wrote in a statement quoted by ABC News.

In connection with the incident at the FBI, the bureau's management appealed to employees to "remain vigilant and not respond to suspicious calls." They were also advised to avoid talking to the media and to report any attempts by the press to contact 911.
