The PDF file contains a large number of embedded URLs, identified as a PDF_SEO_LINK_FARM heuristic. These URLs point to various PDF documents hosted on loaminoo.linkpc.net. While the content of the document body is heavily obfuscated, the presence of numerous external links suggests an attempt to manipulate search engine results or distribute further malicious content. 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.
