The PDF contains a large number of external links, identified as a PDF SEO link farm. The ML classifier also flagged this PDF as malicious. While no scripts were extracted, the sheer volume of links suggests an attempt to manipulate search results or redirect users to potentially malicious content hosted on the 'loaminoo.linkpc.net' domain. The document body was heavily obfuscated and 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.
