MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a call-to-action phrase, strongly suggesting it is a lure for users to download potentially malicious content. The ML classifier also flagged this PDF as malicious. The primary URL, http://netcdn.tw/app/406889139/cheats-coin-master-free-game-hack, appears to be the intended download destination for a game hack or cheat.
