  "This analytics rule identifies network-based indicators such as URLs, IP addresses, and domains related to phishing campaigns, as reported by CYFIRMA threat intelligence. 
  These indicators are flagged with a recommended action to block and are categorized under the 'Phishing' role.
  Such infrastructure is often used to deliver phishing emails, host fake login portals, or redirect victims to credential-harvesting pages. 
  monitoring these indicators proactively helps prevent user compromise and data theft."
