Access to Expired Domain Detected
This rule detects when a network connection is made to a domain that has expired. It leverages WHOIS data to identify domains whose expiration time is before the event timestamp. The rule specifically looks for HTTP network events and joins them with WHOIS information to identify access to recently expired domains. This could indicate access to potentially malicious infrastructure, as expired domains can be re-registered by threat actors for nefarious purposes.
