MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.007 JavaScript

The PDF contains an embedded URI that redirects to a malicious URL, likely intended to deliver a secondary payload or phish for credentials. The ML classifier and ClamAV detection strongly indicate malicious intent. No scripts were extracted, but the presence of external URIs and the document's deceptive content suggest a phishing or malware distribution attempt.
