MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous links to external websites, many of which are related to game hacks and free items, suggesting a lure for users to download potentially malicious content. The ML classifier also flagged this PDF as malicious. While no scripts were explicitly extracted, the presence of embedded URLs and the document's theme strongly indicate an attempt to trick users into visiting malicious sites, likely as a precursor to downloading malware.
