MITRE ATT&CK
T1566.001 Spearphishing Attachment

The document contains embedded URLs and a visual download button, luring the user to click and download a file. The primary URL, http://netcdn.tw/app/479516143/minecraft-free-download-2021-game-hack, suggests the downloaded file is likely a malicious executable disguised as a game hack. The ML classifier strongly flagged this PDF as malicious, supporting the conclusion that it is part of a phishing or malware distribution scheme.
