Reported by CALIFORNIA AG filing
Stanford University disclosed a data breach involving its third-party service provider, Equifax. Between March 1-31, 2016, unauthorized individuals accessed W-2 forms via the W-2Express portal. Affected data included names, addresses, SSNs, dates of birth, and wage/tax information. Stanford disabled the service, notified law enforcement, and offered credit monitoring to affected employees.
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.
