MITRE ATT&CK

T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded links, many of which point to sites offering hacks or cheats for games like Roblox and Coin Master. The heuristic 'PDF_SEO_LINK_FARM' indicates a large number of external links, suggesting a link farm or SEO manipulation tactic. The presence of a download button lure further supports the malicious intent of directing users to external resources.
