MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous URLs and a call-to-action phrase, strongly suggesting a phishing or scam attempt. The ML classifier also flagged this PDF as malicious with high confidence. The primary URL, http://netcdn.tw/app/406889139/free-chest-coin-master-game-hack, indicates the likely intent is to trick users into downloading a second-stage payload disguised as a game hack or cheat.
