The PDF file exhibits a critical heuristic firing for a link farm, containing numerous embedded URLs. These URLs point to external PDF documents hosted on 'loaminoo.linkpc.net'. While the URLs themselves are currently marked as benign, the sheer volume and structure suggest a malicious intent, likely to distribute further malware or lead users to phishing sites. No scripts were extracted from this sample.

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.
