SlowMist analysis Poly Network hacked: the cause of the incident is not keeper private key leakage, but cross-chain contract keeper can be modified

On the evening of August 10, the cross-chain interoperability protocol PolyNetwork was hacked and a total of over 610 million USD was transferred out to 3 addresses, which caused a large amount of assets to be transferred out of the O3Swap cross-chain pool. In this regard, the Slow Fog security team released an analysis report, saying that this attack is mainly because the keeper of the EthCrossChainData contract can be modified by the EthCrossChainManager contract, and the verifyHeaderAndExecuteTx function of the EthCrossChainManager contract can execute the data passed in by the user through the _executeCrossChainTx function. Therefore, the attacker uses this function to pass in carefully constructed data to modify the keeper of the EthCrossChainData contract, not because the keeper’s private key has been compromised and this event occurs.
