The PDF file contains a heuristic firing for a link farm, with 32 external links embedded within the document. The majority of these links point to URLs hosted on 'loaminoo.linkpc.net', which are likely used to distribute malicious content or redirect users to phishing sites. No scripts were extracted from this sample, and the document body was unreadable, limiting further analysis of the specific lure.

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.
