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

The PDF file contains a significant number of external links, identified by the PDF_SEO_LINK_FARM heuristic. These links point to various domains, many of which appear to be part of a link farm designed to manipulate search engine results or distribute malicious content. The document body, though heavily obfuscated, contains references to URLs that are also present in the heuristics, reinforcing the link-distribution attack pattern. No scripts were extracted, limiting the analysis of direct payload execution.

Heuristics 3

  • 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.
  • External URI info PDF_URI
    PDF contains an external URL action
  • 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.
