T1566.001 Spearphishing Attachment

The PDF contains a large number of external links, with one heuristic specifically identifying it as a 'PDF link farm'. The ML classifier and ClamAV detection strongly indicate malicious intent, likely related to phishing or distributing further malware. While no scripts were directly extracted, the PDF structure and embedded URIs suggest it's designed to redirect users to potentially harmful websites.
