MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious File

The PDF was flagged by a machine learning classifier and contains a large number of embedded URLs, indicating a potential link farm or distribution point for malicious content. The heuristic PDF_SEO_LINK_FARM specifically identifies this behavior, suggesting the document's primary purpose is to manipulate search engine results or redirect users to other sites. No scripts were extracted, limiting further analysis of direct payload execution.

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.
