Whois analysis retrieves and examines domain registration information from global Whois databases to spot suspicious or recently created domains that could indicate phishing attempts. This method helps you understand key domain details like the age, ownership, and registration patterns, which can be red flags for malicious activity.
Whois analysis can detect:
Newly registered domains that might have been set up just for phishing campaigns
Domains with suspicious registration patterns or incomplete Whois records
Mismatched registration details that don’t align with the claimed organization
Domains registered via privacy services to conceal true ownership
Domains with upcoming expiration dates, which could indicate temporary use
For example, established organizations often use domains that have been registered for long periods. So, if you get an email from a financial institution using a domain that was registered only a few days ago, that’s a huge red flag.
