MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple embedded URLs and a visual download button, all pointing towards the distribution of a hacking tool for Minecraft. The ML classifier also flagged this PDF as malicious. While no scripts were directly extracted, the presence of malicious URLs and the lure suggest an attempt to trick the user into downloading and executing a secondary payload.
