MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a call-to-action phrase, strongly suggesting a lure to download a malicious payload. The ML classifier also flagged this PDF with high confidence. The primary URL, http://netcdn.tw/app/406889139/coin-master-hack-2021-game-hack, appears to be the intended destination for the user to obtain the advertised game hack.
