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

The PDF document contains multiple embedded URLs and a heuristic firing for a visual download button, suggesting a lure to download malicious content. The ML classifier also flagged this PDF as malicious with high confidence. The document body, though partially corrupted, contains references to game hacks and a URL that likely leads to a second-stage payload.
