Reported by SOUTH CAROLINA AG filing
NextGen Healthcare, Inc. reported a cybersecurity incident in January 2023 involving a BlackCat ransomware attack. The breach was facilitated by stolen client credentials, allowing unauthorized access to systems. Over 1.04 million patient records were affected, exposing PHI, names, DOBs, and SSNs. NextGen engaged forensic investigators, notified law enforcement, and offered 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.
