National Public Data leaked passwords online

Malwarebytes reports that a 277 GB scraped dataset attributed to National Public Data was posted online, allegedly containing hundreds of millions of records and roughly 272 million unique Social Security numbers; a related Records Check site also publicly exposed backend usernames and a shared 6-character default password for users (including an administrator). The article highlights the scale and sensitivity of the leaked PII, notes that exposed files have been removed and the site may cease operations, and provides victim mitigation advice such as changing passwords, enabling strong 2FA, and monitoring identity data.
