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

The PDF file exhibits a 'PDF_SEO_LINK_FARM' heuristic, indicating it contains a large number of external links. These links predominantly point to the same domain, suggesting a coordinated effort to manipulate search engine rankings or to distribute potentially malicious content. No scripts were extracted, and the document body was heavily obfuscated, limiting further analysis of the specific lure. The primary attack pattern observed is the use of a link farm within a PDF document.

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.
