The PDF contains a lure related to Aadhaar card downloads, which is a common tactic for phishing or credential harvesting. It embeds a large number of external links, many of which point to PDF files hosted on suspicious domains, indicating a link farm designed to distribute malicious content. The heuristic 'SE_MFA_LURE' further suggests a credential harvesting intent, possibly to steal session tokens or abuse multi-factor authentication.
