MITRE ATT&CK
T1566.001 Spearphishing Attachment T1203 Exploitation for Client Execution

The PDF document contains numerous embedded URLs and a primary external URI pointing to a download site, disguised with lures for free game currency. The ML classifier strongly flagged this PDF as malicious, indicating a high probability of it being used to deliver a secondary payload. The presence of a download button heuristic further supports the malicious intent of directing users to download an application.
