MITRE ATT&CK

T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains numerous embedded links, many of which point to resources offering cheats and hacks for popular games. The heuristic PDF_SEO_LINK_FARM indicates a mass of external links, and the ML_NYX_PDF_MALICIOUS model strongly flags this PDF as malicious. The presence of a download button lure further supports the malicious intent of directing users to external sites for potentially harmful downloads.
