The PDF file contains a large number of embedded URLs, identified as a 'PDF_SEO_LINK_FARM' heuristic. These links predominantly point to the 'loaminoo.linkpc.net' domain and appear to be designed to manipulate search engine results or distribute further malicious content. While the URLs themselves are currently marked as benign, the sheer volume and nature of the links suggest a malicious intent, likely related to SEO spam or as a distribution vector for other malware. 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.
