Cysic Suspends Bridge Following Unauthorized Mint of 10 Million Tokens

Preliminary investigations reveal the attacker exploited vulnerabilities in the bridge’s message-processing logic to authorize the illicit token creation. While the total unauthorized issuance reached 10 million CYS—representing 1% of the project’s total supply—the actual financial impact remains under review. Cysic successfully blacklisted a wallet containing 2.8 million of the minted tokens roughly 76 minutes after the event, though the status of the remaining 7.2 million tokens is still being traced by security investigators.

The Foundation stated that its mainnet and customer wallet assets remain secure, distinguishing this infrastructure breach from a direct compromise of user funds. Cysic has engaged an external security firm to conduct a forensic audit and determine the exact path of the database intrusion. No timeline has been provided for the resumption of bridge services as the team continues to monitor token movements and potential market impact.
