Reported by CALIFORNIA AG filing
The City of Thousand Oaks notified residents of a data breach involving its third-party payment processing vendor. Between November 21, 2017, and February 26, 2018, an unauthorized individual accessed the vendor's computer, potentially exposing customer names, payment card numbers, and expiration dates. The City engaged forensic investigators and enhanced security protocols.
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.
