MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains an embedded URI and multiple other URLs, presented as a lure for free game items. The ML classifier strongly indicated maliciousness, and the presence of a download-related heuristic further supports a malicious intent. The primary IOC is the direct link to a potential application download.
