Reported by CALIFORNIA AG filing
BookShark LLC reported a data breach involving unauthorized code injected into its website (bookshark.com) between March 11, 2019, and August 26, 2019. The code captured customer login credentials and payment card details (including CVV). BookShark engaged a cybersecurity firm, removed the code, reset passwords, and notified affected California residents via statutory breach notices.
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.
