The PDF file was flagged by a machine learning classifier as malicious and contains a large number of embedded links, indicative of a link farm or SEO spamming technique. The embedded URLs, such as http://loaminoo.linkpc.net/1090091093096096093/Gabby-s-Haunted-House-3-by-Lorrie-Bannett.pdf, are likely used to distribute further malicious content or to manipulate search engine rankings. No scripts were extracted, but the PDF structure itself is the primary vector for malicious activity.

Heuristics 2

  • 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.
