Reported by CALIFORNIA AG filing
Monterey Peninsula Unified School District notified individuals of unauthorized access to its network discovered on November 1, 2021. The investigation determined that files containing current and former employee information, including names, Social Security numbers, medical information, and financial account information, were potentially impacted. The district changed passwords, enhanced security protocols, and engaged third-party specialists. The investigation remains ongoing. No evidence of misuse was found. Credit monitoring was offered.
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.
