MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains multiple embedded URLs, with one prominent URL pointing to a game hack download. The ML classifier strongly flagged this PDF as malicious, and the presence of a visual download button heuristic further supports a malicious intent. The document likely serves as a lure to download a second-stage payload, possibly malware disguised as a game cheat or hack.
