MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded URLs and text promoting game hacks and cheats, strongly suggesting a social engineering lure. The ML classifier also flagged this PDF as malicious with high confidence. The primary URL, http://netcdn.tw/app/406889139/coin-master-hack-version-game-hack, is likely the intended download destination for a malicious payload.
