MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded URLs and a call-to-action phrase, strongly suggesting it is a lure for downloading malicious content. The ML classifier also flagged this PDF with high confidence. The primary URL, http://netcdn.tw/app/406889139/coinmaster-spins-game-hack, is likely the intended download destination for a second-stage payload.
