The PDF file contains a large number of embedded links to external PDF documents hosted on various domains, as indicated by the PDF_SEO_LINK_FARM heuristic. This suggests a link farm or redirection mechanism designed to lead users to potentially malicious content. The ClamAV detection further supports its malicious classification. No scripts were extracted from this sample.

Heuristics 3
