MITRE ATT&CK
T1566.001 Spearphishing Attachment

The ML classifier strongly flagged this PDF as malicious, and it contains numerous embedded URLs pointing to game-related lures. The presence of a visual download button heuristic further supports the idea that the document is designed to trick users into clicking links. The document's content and embedded links suggest a phishing attempt to lure users to download potentially unwanted or malicious files.
