MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a large number of embedded links to external PDF files, hosted on a dynamic DNS domain. This behavior is indicative of a link farm or SEO spam campaign, potentially designed to drive traffic or distribute malicious content disguised as academic papers. No scripts were extracted, and the document body was heavily obfuscated, limiting further analysis of the 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.
