MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple embedded URLs and a heuristic firing for an external URI, all pointing towards a lure for downloading game-related hacks or free currency. The ML classifier also flagged this PDF as malicious. While no scripts were extracted, the presence of numerous links suggests an attempt to redirect the user to a malicious download site.
