MITRE ATT&CK
T1566.002 Spearphishing Attachment

The PDF file contains a large number of embedded links to external PDF documents, disguised as free e-books. This technique is often used to drive traffic to malicious sites or to host malicious content. The heuristic 'PDF_SEO_LINK_FARM' indicates a mass external PDF link farm, suggesting a deceptive content delivery mechanism. No scripts were extracted from this sample.

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.
