Massachusetts data breach notifications

Persons holding personal information about Massachusetts residents must notify the Office of Consumer Affairs and Business Regulation and the Attorney General following discovery of a breach.

How DisclosureLens indexes Massachusetts filings

DisclosureLens polls the Massachusetts AG portal on a regular schedule, fetches each new notice, extracts a structured BreachDisclosure v1 record, resolves the affected entity to its LEI/CIK when possible, and publishes via the REST API (webhooks and STIX/TAXII delivery are planned).

Extraction provenance

Extracted records carry per-field source citations into the Massachusetts AG notice they came from, plus a per-record confidence score and a full extraction audit trail. Massachusetts filings inherit the same BreachDisclosure v1 schema as SEC 8-Ks, HHS OCR notices, and EU DPA registers — same fields, same provenance metadata, deduped against same-incident filings in other jurisdictions.
