Malicious actors often use tactics such as domain hopping or domain fronting to evade detection and propagate malicious activity. By changing the nameservers associated with a domain, threat groups are able toy evade detection and continue their activities under a different set of infrastructure.
By monitoring changes to nameservers associated with a domain, security teams can pinpoint connections between different domains and nameservers, and identify previously unknown threat actors or infrastructure based on different patterns of behaviour.
Additionaly, if a domain is repeatedly changing nameservers or associated infrastructure, it may be an indication that the domain's security controls or practices are inadequate, and that the domain is vulnerable to attack.
