MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous links to external websites, including one explicitly labeled as a game hack download. The presence of a 'download button' heuristic and the ML classifier's high confidence score indicate a malicious intent to trick the user into downloading potentially harmful content. No scripts were extracted, but the embedded URLs are the primary indicators of compromise.
