MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains an embedded URI and multiple external URLs, all related to game hacks and currency, suggesting a lure for phishing or malware. The ML classifier also flagged this PDF as malicious. While no scripts were explicitly extracted, the presence of embedded URIs and the nature of the lures indicate a high likelihood of leading to malicious content.
