National Public Data confirms breach exposing Social Security numbers

National Public Data confirmed that hackers breached its systems and databases, resulting in publicly leaked datasets — reported variants contain up to 2.7–2.9 billion records — potentially including names, emails, phone numbers, mailing addresses and Social Security numbers; the incident traces to a late-December-2023 intrusion with active sharing by multiple threat actors in 2024 and carries high risk for identity fraud and phishing.
