Code-of-Conduct PDF Contains an External Sign-In Link
Detects an inbound policy-themed PDF attachment whose extracted URLs lead to a sign-in, authentication, review, or acknowledgement workflow outside the organisation. This rule specifically looks for PDF attachments in emails where the subject contains terms like 'code of conduct', 'policy', 'compliance', or 'handbook', and the extracted URLs within the PDF contain keywords such as 'login', 'signin', 'auth', 'review', or 'acknowledge'.
