MITRE ATT&CK
T1566.001 Spearphishing Attachment

This PDF file was flagged by multiple heuristics, including ClamAV and an ML classifier, as malicious. It contains a large number of embedded external links to PDF files hosted on various domains, suggesting a link farm or a distribution mechanism for further malicious content. The presence of embedded URLs and the nature of the heuristics strongly indicate a phishing or SEO-based malicious campaign.
