[SlowMist: The 402Bridge attack appears to stem from private key leakage, but insider involvement cannot be ruled out] SlowMist founder Yu Xian posted on the X platform stating that the ownership of the 402Bridge contract was altered, seemingly due to private key theft, but insider involvement cannot be ruled out (this claim does not imply collective wrongdoing by the project team, as it is not a typical rug pull). The domain 402bridge.fun, which was registered just two days ago, has already ceased service, and subsequently, the 'hacker' stole all USDC authorized by users to this bridge contract in bulk. This marks the first publicly reported theft case related to the 402 protocol's services.
