MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a call-to-action phrase, strongly suggesting a social engineering lure for downloading external content. The ML classifier also flagged this PDF as malicious with high confidence. The primary URL, http://netcdn.tw/app/431946152/free-robux-cards-game-hack, is likely the intended download destination for the promised 'free Robux cards'.
