MITRE ATT&CK
T1566.002 Spearphishing Attachment

The PDF contains a large number of embedded URLs, constituting a link farm. The primary heuristic 'PDF_SEO_LINK_FARM' indicates that this PDF is designed to link to numerous other PDF documents hosted on the same domain. While no malicious scripts were extracted, the sheer volume of links and the ML classifier's high confidence score suggest a malicious intent, likely to drive traffic or distribute further malicious content through these links.

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.
