An Eclipse Attack occurs when a malicious actor takes control of a peer-to-peer network connection, isolating a target node from the rest of the network. By doing this, the attacker can provide the target node with misleading information. In a blockchain setting, the attacker can manipulate the target’s view of the blockchain, potentially leading them to make poor decisions. For example, the target might receive false transaction data, making it seem like specific transactions have gone through when they haven’t, or that the blockchain is different than it truly is.This type of attack can be particularly damaging in cases where the target node is involved in critical processes, such as transaction verification or block production. By controlling the information flow to the target node, the attacker can disrupt normal operations, cause loss of funds, or influence consensus.Eclipse Attacks highlight the importance of maintaining secure and diverse network connections to minimize the risk of being isolated by a single adversarial source.
