National Public Data Breach: Are Your Details Among the 2.9 Billion Leaked?

National Public Data Breach Leak Hacker SSN Stolen

Key Takeaways

  • Massive Scale: The hacker group USDoD leaked an unencrypted database containing 2.9 billion rows of personal data from US, UK, and Canadian citizens.
  • Highly Sensitive Data: Unlike a simple password leak, this breach includes Social Security Numbers (SSNs), full names, decades of physical addresses, and familial relationships.
  • Background Check Nightmare: National Public Data operates by scraping non-public records. You likely never created an account with them, but they had your data anyway.
  • Immediate Action Required: If your data was in this breach, you must freeze your credit with all three major bureaus immediately to prevent loans from being taken out in your name.

In what cybersecurity experts are calling one of the most severe privacy disasters of the decade, a data broker known as National Public Data (NPD) suffered a catastrophic breach. A cybercriminal group operating under the alias USDoD successfully exfiltrated and leaked an unencrypted database containing 2.9 billion records.

Why This Breach is Different

Most data breaches involve a specific website where you created an account, like Ticketmaster or Yahoo. You can usually fix the problem by changing your password. The National Public Data breach is fundamentally different.

NPD operates in the shadows as a background check company. They scrape billions of public and non-public records from court documents, state databases, and other data brokers. You never agreed to give them your data, yet they compiled a massive dossier on you. Because of the nature of background checks, the leaked data includes:

  • Social Security Numbers (SSNs)
  • Decades of Historical Physical Addresses
  • Full Legal Names (including maiden names)
  • Familial Relationships and Relatives

⚠️ The Identity Theft Threat

With your full name, current and past addresses, and your Social Security Number, criminals have everything they need to open credit cards, take out massive personal loans, or file fraudulent tax returns in your name.

How to Protect Yourself Right Now

1. Freeze Your Credit (Mandatory)

You cannot change your Social Security Number. The only way to stop someone from taking out a loan in your name is to initiate a security freeze with the three major credit bureaus: Equifax, Experian, and TransUnion. A freeze is free and prevents lenders from viewing your credit report, effectively blocking new loans.

2. Check Your Email Exposure

While NPD primarily leaked background check data, criminals combine this data with emails found in other breaches to launch highly targeted phishing attacks. Use our real-time scanner to see exactly what other databases your email has appeared in.

3. Beware of Targeted Scams

Because the leak includes information about your family members, expect scammers to use this to build trust. Be extremely skeptical of phone calls or text messages from people claiming to be your bank, the IRS, or even family members asking for money.

Identity theft can ruin your financial future. We highly recommend investing in dedicated identity theft protection services if you suspect your SSN has been compromised.

Frequently Asked Questions

How did National Public Data get my information?

Data brokers like NPD scrape public records, court filings, property deeds, and purchase data from other brokers to build massive profiles on citizens. You do not need to create an account for them to have your data.

Can I get a new Social Security Number?

The Social Security Administration rarely issues new numbers. Even if you are a victim of severe identity theft, getting a new SSN is incredibly difficult and causes massive issues with your credit history. Freezing your credit is the standard protocol.

Is freezing my credit permanent?

No. You can easily 'thaw' or lift your credit freeze temporarily using an app or website when you legitimately need to apply for a loan, mortgage, or new apartment.

How do I know if someone opened a credit card in my name?

You should request your free annual credit report from all three bureaus and review it for accounts you do not recognize. Alternatively, sign up for a credit monitoring service like Credit Karma.

Is there a class action lawsuit against National Public Data?

Yes. Multiple class-action lawsuits have been filed against Jerico Pictures Inc. (the company doing business as National Public Data) for failing to secure this highly sensitive information.

Expert Security Advisory

If your credentials were leaked in this threat vector, immediately migrate your accounts to an end-to-end encrypted architecture.
