Multi-Chain Attack Vector

Definition

A multi-chain attack vector is a vulnerability that spans across multiple interconnected blockchain networks. This type of security risk arises from the interoperability between different blockchains, where a weakness in one chain, bridge, or cross-chain protocol can compromise assets or data on another connected chain. Attackers might exploit inconsistencies in security models, oracle manipulations, or bridge smart contract flaws to move illicitly obtained assets or disrupt multiple ecosystems. The increasing adoption of multi-chain architectures amplifies the potential impact of such coordinated attacks.
