MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a lure for free spins on Coin Master, directly linking to a URL that likely hosts a malicious payload. The ML classifier strongly flagged this PDF as malicious, and the presence of an external URI further supports a malicious intent. No scripts were extracted, but the document's content and external link suggest a phishing or malware distribution attempt.
