【Cysic 跨链桥遭到攻击，黑客未经授权铸造了 1000 万枚 CYS】
Cysic added that the attack occurred on October 17 after the attacker gained access to a database related to the cross-chain service and submitted false mint messages; the incident was limited to the bridge's message-processing and minting functions, did not affect the Cysic mainnet or existing assets in user wallets, and the team hired a security firm to investigate the attack path and trace funds.
State after update: The Cysic cross-chain bridge remains paused, the involved address is blacklisted on-chain with about 2.8 million CYS frozen, and the project says the mainnet and user wallet assets were unaffected while a security firm investigates and traces funds.
