Unknown Data Broker

In April 2021, a hacker using the online handle Pompompurin published a database containing household and personal records on roughly 250.8 million United States residents, according to reporting by Hackread and Bitdefender. The dump, about 263 GB spread across more than 1,200 CSV files, appeared on the hacking forum RaidForums. The person or company that originally collected the data has never been identified, which is why our investigation team indexes it under "Unknown Data Broker." Hackread reported that the data appears to have come from an open Apache Solr instance hosted on Amazon Web Services, accessed by the hacker before it was removed or reassigned. No company notice was ever issued because no responsible organization has come forward.

What Are the Potential Risks for Affected Individuals?

This data is unusually detailed for a leak of this size. It pairs identities and contact details with financial profiles: salary, credit range, and home value. Scammers can use that combination to craft convincing pitches, such as fake mortgage refinance offers aimed at homeowners with specific equity levels.
