The PDF contains a large number of external links, identified by the PDF_SEO_LINK_FARM heuristic, suggesting a malicious intent to manipulate search engine results or redirect users. The ML_NYX_PDF_MALICIOUS heuristic further supports the malicious classification. No scripts were extracted from this sample, and the document body was heavily obfuscated, limiting further analysis of the specific lure. The primary IOCs are the numerous external URLs embedded within the 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.
