Domain rotation is a technique where cybercriminals frequently change the website addresses (domains) they use to host malicious content or command-and-control servers. By regularly switching domains, attackers make it harder for security systems and law enforcement to detect, block, or take down their operations. This method is commonly used in phishing campaigns, malware distribution, and botnet management to maintain access and avoid blacklisting. Domain rotation complicates efforts to track and stop online threats, as defenders must continuously update their security measures to keep up with new domains.
