MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple embedded URLs and a primary external URI pointing to a file disguised as a game hack. The ML classifier strongly flagged this PDF as malicious, indicating it likely serves as a lure to download a second-stage payload. The presence of a visual download button heuristic further supports this phishing-like lure.
