The PDF contains a large number of embedded links to external PDF files, hosted on the dynamic DNS domain loaminoo.linkpc.net. This behavior is indicative of a link farm or a redirection scheme designed to lead users to potentially malicious content. No scripts were extracted, and the document body was unreadable, limiting further analysis of the specific lure. The ML classifier strongly supports the malicious verdict.

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.
