MITRE ATT&CK
T1566.001 Spearphishing Attachment

The document contains embedded URLs and a call-to-action phrase, strongly suggesting a social engineering lure. The primary URL, http://netcdn.tw/app/406889139/coin-master-free-spins-and-coins-app-game-hack, is presented as a download for in-game currency, likely a pretext to deliver a malicious payload. The ML classifier also flagged this PDF as malicious with high confidence.
