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.

The Republican Governors Association (RGA) notified the New Hampshire Attorney General of a data breach involving 4 state residents. Threat actors exploited a vulnerability in Microsoft Exchange Server to access RGA's email environment between February and March 2021. While forensic investigators could not confirm what specific data was accessed, the breach notification letter indicates that some residents' names, Social Security numbers, or payment card information may have been accessible. RGA implemented Microsoft patches, offered two years of credit monitoring, and notified the FBI and state regulators.
