MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.002 Malicious Link

The PDF contains a large number of embedded links to other PDF files hosted on various domains, as indicated by the PDF_SEO_LINK_FARM heuristic. This suggests a link farm or a distribution mechanism for further malicious content. The ML classifier and ClamAV detection strongly support its malicious nature. No scripts were extracted, and the document body was heavily truncated and unreadable, making it impossible to determine a more specific attack pattern or intent beyond link distribution.
