Reported by NEW HAMPSHIRE AG filing
The Ohio History Fund was created to support the preservation and sharing of Ohio's heritage by funding local, regional, and statewide projects, programs, and events related to the broad sweep of the state's history and pre-history.
Ohio Historical Society experienced a ransomware attack on July 9, 2023, resulting in data encryption and exfiltration. Cybercriminals demanded ransom, which was rejected. Three New Hampshire residents were affected. The organization notified the FBI, engaged forensic consultants, and offered credit monitoring.

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.
