ShinyHunters Claims 3.1TB NAIC Insurance Data Breach
Data exposed:

  • financial statements
  • statistical reports
  • credit ratings
  • PII

The ShinyHunters group has added NAIC.org to its leak site, claiming a 3.1 terabyte trove of data stolen from the National Association of Insurance Commissioners and connected insurance reporting platforms. The exposed information includes regulatory filings, financial statements, statistical reports, credit ratings, and personally identifiable information drawn from systems such as INSData, SERFF, and state insurance databases.

Public reporting indicates the actors posted more than 105,000 files and warned that they would begin releasing the material unless contacted by June 22. The breach affects insurers across the country, with records that can contain names, addresses, Social Security numbers, employer identification numbers, and other details submitted during routine regulatory processes. Available reporting describes the data as originating from platforms used by insurance companies to file information with state regulators and the NAIC itself. No confirmed statement from NAIC had been issued at the time of initial reporting.
