2026 Chinese crypto traders — ~1M PII lines marketed on dark-web forums (unverified sale listing)
Data compromised
PII lines marketed for Chinese crypto-trader identities per forum listings
Technical writeup
Cyber-threat roundups in early 2026 (including BitSight underground research and security-industry breach summaries) cited criminal marketplace marketing of roughly one million lines of personally identifiable information tied to Chinese cryptocurrency traders—names, contact details, and trading-adjacent metadata offered for sale rather than a single exchange perimeter hack with a company attestation. BreachHistory indexes this as an unverified dark-web PII listing cluster; treat volume as seller marketing until a named platform confirms forensic scope.
Root cause
Dark-web marketplace sale listing / PII aggregation (no single attested corporate intrusion)
