MITRE ATT&CK

T1566.001 Spearphishing Attachment T1204.002 Malicious Link

This PDF document contains a large number of embedded links, many of which point to external resources related to game cheats and hacks. The heuristic 'PDF_SEO_LINK_FARM' indicates a mass of external links, suggesting a link farm or SEO manipulation tactic. The presence of a download button lure further supports the intent to direct users to external content, likely malicious.
