MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains multiple embedded URLs that lead to websites offering cheats and free in-game currency for popular games like Coin Master and Roblox. The ML classifier strongly flagged this PDF as malicious, and the presence of these lures suggests a phishing or scam attempt. No scripts were extracted, but the document's primary function appears to be directing users to potentially malicious external sites.
