The PDF was flagged by a machine learning classifier and contains a large number of embedded links, many of which point to numeric slugs on the 'loaminoo.linkpc.net' domain. This heuristic strongly suggests a link farm or SEO manipulation tactic, which can be used to distribute malicious content or improve the ranking of malicious sites. No scripts were extracted, and the document body was unreadable.

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.
