MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a lure for free Coin Master spins, directing users to a suspicious URL. The ML classifier strongly flagged this PDF as malicious, and the presence of embedded URIs further supports a malicious intent to redirect users to potentially harmful content. No scripts were extracted, but the overall pattern suggests a phishing or malware distribution attempt.
