Understanding Fast Flux Networks

Fast flux networks are designed to obscure the location of a hacker’s command and control server by rapidly changing the IP addresses associated with a domain name among multiple compromised hosts in a botnet. This technique significantly complicates efforts by network defenders to block access, as these IP addresses change every few minutes, making it near impossible to track down the attackers. An example of this in action was the Stormworm Fast Flux network, which, following a malicious Trojan release, compromised nearly 2 million hosts in its operation. Such networks provide a strategic advantage to cyber adversaries, as they hinder law enforcement's ability to trace the origins of the attack due to the sheer volume of rapidly changing relay points.
