Reported by VERMONT AG filing
Haydon Corporation notified Vermont AG of a data breach discovered on November 27, 2022. Unauthorized access to company systems resulted in the exposure of names, SSNs, financial account numbers, and health plan enrollment data. The company engaged law enforcement, secured the network, and offered one year of Equifax credit monitoring to affected individuals.
About this clustering
DisclosureLens links filings into incidents through layered matchers: deterministic rules (same source document, multistate filings of one breach, tight-window same-victim pairs), a weighted-similarity scorer for cross-source candidates, and an operator review queue for everything uncertain. Each link records its own method and confidence — shown per filing in the timeline below. The system defaults to NOT merging when uncertain, because a false merge (collapsing two unrelated breaches) is more harmful than a false split (showing related filings separately); uncertain pairs route to human review instead of auto-merging. Filing summaries shown in the timeline are AI-generated extracts — verify each against its linked source.
