MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a large number of embedded links to other PDF files, a technique often used for SEO manipulation or to distribute malicious content. The heuristic 'SE_ADVANCE_FEE_SCAM_LURE' strongly suggests the document's content is designed to trick users into fraudulent financial transactions. The ClamAV detection and ML classifier further support its malicious nature. No scripts were extracted, but the primary attack pattern involves directing users to external malicious links.
