MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a lure related to online games like Roblox and Coin Master, suggesting a phishing or scam attempt. The presence of an external URI pointing to 'netcdn.co' strongly indicates a download attempt for a secondary payload. While no scripts were directly extracted, the ML classifier flagged the PDF as malicious with high confidence, supporting the suspicious nature of the document.
