[x402 Cross-Chain Protocol @402bridge Suspected of Security Vulnerability, User Funds Transferred to Arbitrum] The GoPlus Chinese community has issued a security warning stating that the x402 cross-chain protocol @402bridge is suspected to have encountered a security incident. The creator of the contract address starting with 0xed1A has transferred the Owner permissions to the 0x2b8F address. The new Owner subsequently invoked the transferUserToken method in the contract to transfer all remaining USDC from authorized user wallets. Since users did not limit the authorization amount when granting permissions to the @402bridge contract, approximately 200 users had their remaining USDC transferred, totaling 17,693 USDC. After the funds were transferred, they were exchanged for ETH and moved to Arbitrum through multiple cross-chain transactions. Users participating in this project are advised to immediately revoke related authorizations and confirm the interaction address is the official address before granting permissions. Only authorize necessary amounts and avoid unlimited authorizations. Additionally, regularly check authorization statuses and revoke unnecessary authorizations.
