MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous links to external websites, many of which are disguised as download pages for game-related cheats and currency. The ML classifier strongly flagged this PDF as malicious, and the presence of these lures indicates an attempt to trick users into downloading potentially harmful files. No scripts were extracted, but the embedded URLs are the primary indicators of malicious intent.
