The PDF file was identified as malicious due to a critical heuristic firing for a PDF SEO link farm. It contains numerous embedded URLs, all pointing to the domain 'loaminoo.linkpc.net', which are likely used to manipulate search engine rankings or distribute further malicious content. No scripts were extracted, and the document body was unreadable, limiting the ability to determine the exact payload or delivery mechanism beyond the link farm.

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.
