T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains a lure related to probability tables, directing the user to a suspicious URL. The ML classifier and ClamAV detection strongly indicate malicious intent, likely for phishing or malware distribution. No scripts were extracted, but the presence of an external URI and the document's deceptive content point towards a phishing attack.
