MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded URLs and a heuristic firing for an external URI, all pointing to sites offering game hacks and cheats. The ML classifier strongly indicates maliciousness, suggesting the document is designed to trick users into downloading malware disguised as game-related content. No scripts were extracted from this sample.
