Reported by CALIFORNIA AG filing
Alameda Health System notified California AG in 2022 regarding unauthorized access to employee email accounts from May 2020 to March 2022. The breach exposed patient PII, including names, SSNs, driver's license numbers, and clinical/insurance data. AHS engaged forensic investigators and offered one year of credit monitoring.
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.
