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

The PDF file contains a large number of embedded URLs, forming a link farm. The heuristic 'PDF_SEO_LINK_FARM' indicates that these links are likely used for SEO manipulation or to distribute further malicious content. While the specific intent of the link farm is not fully clear from the provided data, the sheer volume and the nature of the heuristic suggest a malicious distribution or redirection scheme. 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.
