MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded URLs that lead to websites offering game hacks and free in-game currency, such as for Coin Master and Roblox. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs further supports a malicious intent to redirect users to potentially harmful sites. No scripts were extracted, but the document's structure and embedded links suggest a phishing or scam attempt.
