RulenameInfoblox - TI - InfobloxCDC Match Found - Lookalike Domains
DescriptionInfobloxCDC Lookalike Domain match found in your Infoblox TIDE Threat Intelligence. Customize query count, scheduling, responses and more. Modify data sources, types and threat properties as desired. This rule depends on a parser based on a Kusto Function to work as expected called **InfobloxCDC**.
