Reported by IDAHO AG filing
Marsh Valley School District No. 21 notified the Idaho Attorney General on January 9, 2025, of a data breach involving its PowerSchool Student Information System. An unauthorized party accessed student and teacher data using compromised credentials. The district engaged CyberSteward and CrowdStrike for investigation and negotiated with the attacker to destroy stolen data.
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.
