It indicates that the SSL certificate associated with the domain has been newly created or issued. This behavior often coincides with newly registered or reactivated domains and can signal the setup phase of phishing, malware distribution, or C2 infrastructures.
The questions every analyst asks before acting on this signal.

Because threat actors frequently obtain and deploy SSL certificates immediately before launching campaigns to make malicious domains appear legitimate. Tracking newly-issued certificates helps identify emerging threats early in their lifecycle.
Yes. Legitimate sites regularly renew or reissue SSL certificates for maintenance and compliance reasons. However, correlation with other indicators, such as domain age, category, and hosting reputation, helps analysts assess risk more accurately.
