T1204.002 Malicious Link
This PDF document contains a significant number of external links, many of which are disguised as PDF files hosted on suspicious domains. The ML classifier also flagged this document as malicious. The presence of a 'download button' heuristic further suggests a user-interaction-based lure. The primary attack pattern involves directing users to potentially malicious content via these links.
