MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document was flagged by a machine learning classifier and contains a large number of embedded URLs, indicating a link farm designed to redirect users to malicious sites. While no scripts were explicitly extracted, the presence of numerous external links suggests the PDF is intended to lure users to external resources, likely for further exploitation or malware delivery. The ML_NYX_PDF_MALICIOUS heuristic strongly supports the malicious nature of this file.

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.
