MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple embedded URLs, including one pointing to a "coin-master-hack-spin-game-hack" executable. The ML classifier strongly flagged this PDF as malicious, and the presence of a download button heuristic further supports a malicious intent. The document likely serves as a lure to trick users into downloading and executing a malicious payload.
