The PDF contains a large number of embedded links to external PDF files, a technique often used for SEO manipulation or to distribute further malicious content. The ClamAV detection and ML classifier strongly indicate malicious intent. The heuristic PDF_SEO_LINK_FARM rule specifically identifies the mass external PDF link farm, with the first URL being http://agl-llc.com/uploads/1/3/0/4/130483956/lutejerorawaba_pesaj_perumuxeb.pdf. No scripts were extracted from this sample.

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM
    Small PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
  • 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.
