MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file contains an embedded URI pointing to a URL associated with game hacks, and the document body includes a similar URL. A machine learning classifier also flagged the PDF as malicious. While no scripts were extracted, the presence of the malicious URL and the ML classification suggest an attempt to trick the user into downloading malware.
