The PDF contains a large number of external links, identified by the PDF_SEO_LINK_FARM heuristic, suggesting a tactic to manipulate search engine results or distribute content. The ML classifier also strongly indicated maliciousness. While no scripts were extracted, the sheer volume of links hosted on the 'loaminoo.linkpc.net' domain points towards a distribution or redirection mechanism. The primary intent appears to be SEO manipulation or acting as a gateway to other malicious content.

  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
