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

The ML classifier strongly flagged this PDF as malicious, and it contains multiple embedded URLs pointing to game-related hacks and cheats. The document body, though partially corrupted, includes text and URLs that reinforce the lure of free in-game currency or items. The presence of a visual download button heuristic further supports the malicious intent of directing users to download potentially harmful content.
