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

The PDF contains multiple embedded URLs, with one prominent URL pointing to a game hack download. The ML classifier strongly flagged this PDF as malicious, and the presence of download-related text further supports a malicious intent. The primary goal appears to be tricking the user into downloading a secondary payload disguised as a game hack.
