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

The PDF document contains multiple embedded URLs, including one that points to a potential payload download. The ML classifier strongly flagged this PDF as malicious, and the presence of a call-to-action phrase further supports a malicious intent. The document body, though partially corrupted, contains references to game hacks and cheats, aligning with the observed URLs.
