MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple embedded URLs that lead to pages offering 'free' in-game currency or items for popular games like Coin Master and Roblox. The ML classifier strongly flagged this PDF as malicious, and the presence of these download lures suggests an attempt to trick users into downloading further malware. Although no scripts were explicitly extracted, the PDF structure and embedded URIs are indicative of a phishing or malware distribution attempt.
