IHS Inc, a payment processing subsidiary, notified customers of a cyber attack where unauthorized parties accessed databases containing names, contact info, usernames, passwords, and payment card numbers. The incident was discovered in Feb 2013, affecting data accessed around Nov 2012. IHS engaged law enforcement and forensic experts, reset passwords, and enhanced security safeguards.
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.
