T1204.002 Malicious Link
The PDF contains a large number of external links, many of which are SEO-optimized and point to PDF files related to game hacks and free accounts. The heuristic 'PDF_SEO_LINK_FARM' indicates a mass of external links, and the ML classifier flagged the PDF as malicious. The presence of a 'download button' lure further suggests a malicious workflow aimed at tricking users into clicking these links.
