MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded URLs, many of which are related to game hacks and cheats, suggesting a lure to download malicious files. The ML classifier also flagged this PDF as malicious with high confidence. While no scripts were explicitly extracted, the presence of external URIs and the ML detection strongly indicate a malicious intent to redirect users to potentially harmful content.
