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.
Hammer Nutrition notified customers of a data breach affecting payment card data. The intrusion occurred on a third-party website provider's systems between January and October 2018. Attackers placed malware on the servers to access debit/credit card numbers, expiration dates, and CVV codes. No other customer information was accessed. The company engaged a cybersecurity firm to remove malware, installed a web application firewall, and switched to a third-party hosted payment provider.
