MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.007 JavaScript

The PDF document contains numerous links to external websites, many of which are related to popular games like Coin Master and Roblox, suggesting a lure for users seeking in-game advantages. The ML classifier strongly flagged this PDF as malicious, and the presence of embedded URLs further supports a malicious intent. While no scripts were explicitly extracted, the PDF structure and embedded URIs indicate a phishing or scam attempt.
