Eclipse attacks are a sort of cyberattack in which an attacker creates a fake environment around a single node or user, allowing the attacker to manipulate the node into doing a malicious action.
What can blockchain developers learn from eclipse attacks?Developers can familiarize themselves with the vulnerabilities in Bitcoin nodes that can be exploited to replace legitimate peer addresses with their own.Technically, when the node selects IP addresses from the tried bucket with timestamps, it increases the probability of the attacker getting selected. This is true even if the attacker only owns a small portion of these addresses. Chances of getting selected can also be increased by increasing the attack time.When an address bucket is full, one address is removed at random. If an attacker’s IP is the one removed, then it can eventually be inserted if it is repeatedly sent to the node.As you can see, attackers can exploit th
