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

The PDF contains embedded URLs and a document body that attempts to trick the user into downloading content by posing as a free game hack. The ML classifier strongly flagged this PDF as malicious, and the presence of multiple external URIs further supports a malicious intent to redirect the user to potentially harmful resources.
