Eclipse Attack

Eclipse Attack is a type of attack in the cryptocurrency world where an attacker gains control of a victim's blockchain node and isolates it from the rest of the network. The attacker then sends fraudulent transactions to the victim's node, which the node believes are valid because it is unable to see the rest of the network.

Eclipse attacks can occur in several ways, including by compromising the victim's internet connection or by creating a large number of fake nodes that surround the victim's node on the network. Once the victim's node is isolated, the attacker can execute various attacks, including double-spending and transaction censorship.

To prevent eclipse attacks, cryptocurrency users should take several precautions, including using secure hardware wallets and nodes, avoiding public Wi-Fi networks, and verifying the authenticity of nodes before connecting to them. In addition, cryptocurrency networks should implement measures to detect and prevent eclipse attacks, such as monitoring network traffic and using secure peer discovery mechanisms.

Eclipse attacks can have significant consequences for cryptocurrency users, including financial losses and damage to the integrity and reputation of the cryptocurrency network. By taking appropriate precautions and implementing effective security measures, however, users can minimize the risk of eclipse attacks and ensure the security and reliability of their cryptocurrency transactions.
