MITRE ATT&CK
T1566.001 Spearphishing Attachment

The document contains multiple embedded URLs, with a primary focus on 'coin-master-gold-cards-hack-game-hack' hosted on netcdn.tw. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs suggests an attempt to redirect the user to a download site. Although no scripts were explicitly extracted, the overall structure and content indicate a phishing or malware distribution attempt.
