MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and text promoting a "Coin Master Hack", suggesting a lure for users to download potentially malicious content. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs further supports a suspicious nature. No scripts were extracted, but the document's content and embedded links indicate a phishing or malware distribution attempt.
