The Cysic Foundation reports that the attacker accessed a database supporting bridge services and exploited a processing-logic vulnerability to submit a fraudulent mint message, creating 10,000,000 CYS on BNB Smart Chain at 12:31:38 UTC on October 17, 2026. The recipient address was blacklisted at 13:47:52 UTC, restricting roughly 2.8 million CYS still held there. Per the foundation, mainnet, consensus, and user-held assets were unaffected, and the bridge remains suspended pending a full security review. A professional security firm is tracing funds; actual losses and the full attack path remain under investigation.
