MITRE ATT&CK
T1566.002 Spearphishing Attachment

The PDF heuristic 'PDF_SEO_LINK_FARM' indicates the presence of numerous external links, suggesting a link-farming or traffic-driving scheme. The ML classifier also flagged the document as malicious. While no scripts were extracted, the sheer volume of links points to a non-standard document purpose, likely related to SEO manipulation or directing users to potentially malicious content hosted on the linked domains.

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.
