MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains multiple embedded URLs and a call-to-action phrase, strongly suggesting a lure for users to download potentially malicious content or visit phishing sites. The ML classifier also flagged this PDF with high confidence. The primary malicious URL identified is http://netcdn.tw/app/406889139/coin-master-link-game-hack, which is likely used to distribute a second-stage payload.
