Reported by CALIFORNIA AG filing
San Leandro Unified School District (SLUSD) notified the California AG of a breach involving its Aeries Student Information System. An unauthorized individual exploited a software vulnerability to access student and parent data, including names, addresses, emails, and hashed passwords. The perpetrator was taken into police custody. SLUSD required password resets and applied a software patch to remediate the vulnerability.
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.
