Cysic Bridge Exploit Creates 10 Million Tokens Before $727,000 Moves To Ethereum
Summary
Cysic suspended its cross-chain bridge after an attacker minted 10 million unauthorized CYS tokens on BNB Chain. On-chain analysis traced the sale of about 7.2 million tokens and the movement of 306.6 ETH, worth roughly $727,000 at the time, toward Ethereum. Cysic blocked an address and halted the bridge, but only after some tokens had been traded. The incident may have affected CYS’s price and liquidity, while leaving users uncertain about valid balances. Cysic must investigate the message-verification failure and outline corrective measures before restoring bridge operations.
