Hackers leak 2.7 billion data records with Social Security numbers

A massive data breach allegedly originating from National Public Data exposed nearly 2.7 billion plaintext records — including names, mailing addresses, and social security numbers — which were shared and partially leaked by multiple threat actors (USDoD, Fenice, SXUL) on hacking forums. The leak poses extensive identity theft and fraud risk, has prompted class-action litigation, and the exposed PII is unencrypted and likely includes outdated or inaccurate entries.
