MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.002 Malicious Link

The PDF contains a large number of embedded external links, as indicated by the PDF_SEO_LINK_FARM heuristic. The ML classifier also flagged the document as malicious. While no scripts were extracted, the sheer volume of links suggests an attempt to manipulate search engine results or redirect users to potentially harmful websites. The document body was not sufficiently readable to determine a 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.
