Website Tied to Largest Ever SSN Leak Quietly Returns, Putting Your Personal Data Back In Reach

National Public Data-the background-check website at the center of last year’s Social Security number fiasco-has reappeared as a free people-search portal.

The site now exposes names, addresses, phone numbers, and more, while offering an online opt-out form that promises to remove profiles on request. Privacy reporters at PCMag first flagged the relaunch and tested removals, noting that results disappeared promptly during their checks.

The relaunch follows a breach that ricocheted across criminal markets in 2024. A seller using the handle “USDoD” advertised 2.7-2.9 billion rows tied to the company; subsequent analyses suggested the cache held hundreds of millions of unique SSNs amid heavy duplication.

KrebsOnSecurity reconstructed the early sales posts and the spread of samples, while lawsuits described a trove of “nearly 2.99 billion” records.

The company later acknowledged the incident. A support advisory summarizing its account traces the initial intrusion to December 2023, with data surfacing from April into the summer of 2024. Independent reporting confirmed that stolen databases containing Social Security numbers were leaked widely as the company struggled to contain the fallout. Confirmation of the breach was followed by a wave of class-action filings.

By October 2024, the operator sought Chapter 11 protection amid mounting litigation, and Bloomberg Law documented complaints alleging exposure on a near-unprecedented scale. Even as the domain changed hands, the public-facing service now says it aggregates records from “publicly available sources,” putting fresh attention on how easily disparate data points can be pulled into a single, search-ready profile.

Regulators have pressed the company over compliance unrelated to the hack itself: California’s privacy watchdog ordered a fine for failing to register as a data broker, a requirement intended to make such firms-and their opt-out channels-easier to find. The enforcement underscores a broader reality: legal remedies can penalize noncompliance, but once data is copied and shared, it is extraordinarily difficult to claw back.

On social platforms, guides to removing listings are circulating widely. The post below highlights the return of the site and a direct path to submit a suppression request.
