T1566.001 Spearphishing Attachment
T1204.002 Malicious Link
The PDF document contains numerous links to external websites, many of which are SEO-optimized to appear as guides for obtaining in-game currency or cheats for popular games like Roblox and Coin Master. The heuristic 'PDF_SEO_LINK_FARM' indicates a large number of such links, and the ML classifier strongly flagged this PDF as malicious. The primary URL, http://netcdn.tw/app/431946152/how-to-get-free-robux-on-android-game-hack, likely serves as the initial lure or payload delivery.
