MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains an embedded URL that directs users to a download page for 'coin-master-gift-link-hack-game-hack'. The ML classifier flagged this PDF with high confidence, and the presence of a download-related heuristic further supports a malicious intent. The document body, though heavily obfuscated, contains references to the URL and the game, reinforcing the lure.
