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

The PDF document contains a clear lure for a "Coin Master Hack" and embeds numerous URLs pointing to game-related cheats and hacks. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs and a visual download button further supports a malicious intent to redirect users to potentially harmful content. No scripts were extracted, but the document's structure and embedded links indicate a phishing or social engineering attempt.
