    Article Summary

    Historical WHOIS data can provide valuable information about the ownership and registration of domains and IP addresses associated with potential threats. For example, information such as the name and contact information of the domain owner can be used to verify the legitimacy of a website or to identify potential sources of phishing or malware distribution.

    WHOIS data can be used to identify patterns and connections between different domains and IP addresses, as well as between different threat actors. By monitoring WHOIS data, security teams can detect and respond to changes that may indicate potential threats, such as the creation of new subdomains or changes to the IP addresses associated with a domain.

    Silent Push provides organizations with a historic WHOIS lookup function that can be modified to return results based on sample intervals and changed records.
