Genuine DocuSign envelope leading to counterfeit share-notice phishing link
Detects a specific phishing pattern where a legitimate, authenticated DocuSign notification is followed by a user clicking a link within that document that redirects to known malicious infrastructure or OAuth-abuse sites (e.g., .vu domains, credential harvesting proxies). This heuristic identifies the link as being embedded in the shared document rather than the email body.
