MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a clear lure for a "Coin Master Spin Hack" and embeds a URL pointing to a download. The ML classifier strongly flagged this PDF as malicious, and the presence of an external URI further supports a malicious intent to deliver a payload. No scripts were extracted, but the overall structure and embedded URL suggest a phishing or malware distribution attempt.
