MITRE ATT&CK
T1566.001 Spearphishing Attachment T1203 Exploitation for Client Execution

The PDF document contains numerous embedded URLs, with a primary one pointing to a game hack download. The ML classifier strongly flagged this PDF as malicious, and the presence of a download button heuristic further supports a malicious intent. The document's content and heuristics suggest it is designed to trick users into downloading and executing a secondary payload.
