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

The ML classifier strongly flagged this PDF as malicious, and it contains an embedded URI pointing to a download site for game hacks. The document body also contains multiple URLs related to free in-game items and hacks, suggesting a lure to download a payload. The presence of a visual download button heuristic further supports this malicious workflow.
