Reported by CALIFORNIA AG filing
Yuba City Unified School District notified California AG in November 2019 regarding a data breach involving its Aeries Student Information System. An unauthorized individual exploited a software vulnerability to potentially access parent and student data, including names, addresses, emails, and hashed passwords. The District reset all passwords, patched the vulnerability, and cooperated with law enforcement.
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.
