MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document was flagged by a machine learning classifier as malicious and contains a large number of external links, indicating a potential link farm or distribution mechanism. The heuristic 'PDF_SEO_LINK_FARM' specifically calls out the mass external PDF link farm. While no scripts were extracted, the sheer volume of links suggests an attempt to manipulate search engine results or lead users to malicious content.

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.
