Reported by SEC 10-K Item 1C filing
Quantum-Si, Inc. disclosed in its 10-K that in August 2020, it discovered ransomware on a server. The company engaged third-party forensics experts and outside counsel. No employee or personal data was accessed, and no ransom was paid due to sufficient backups. Security enhancements were implemented during and after the incident.
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.
