MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a significant number of embedded URLs pointing to external PDF files, as indicated by the PDF_SEO_LINK_FARM heuristic. While the document body is heavily obfuscated, the presence of numerous links suggests an attempt to manipulate search engine rankings or distribute content from a specific domain. The ML_NYX_PDF_MALICIOUS heuristic further supports the malicious classification.

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.
