MITRE ATT&CK
T1566.002 Spearphishing Attachment

The PDF file contains a large number of embedded URLs pointing to external PDF documents. The heuristic PDF_SEO_LINK_FARM indicates this is a link farm, likely intended to drive traffic or SEO for the domain loaminoo.linkpc.net. While the URLs themselves are marked as benign, the sheer volume and the nature of the heuristic suggest a malicious intent to abuse search engine indexing or to distribute potentially harmful content disguised as legitimate documents.

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.
