MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded URLs and a "download button" lure, strongly suggesting an attempt to trick the user into downloading malware or visiting a malicious site. The ML classifier also flagged this PDF as malicious with high confidence. The primary URL http://netcdn.tw/app/406889139/free-spin-and-coin-links-game-hack is likely the intended download destination.
