MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a large number of embedded URLs, identified by the PDF_SEO_LINK_FARM heuristic, which suggests a link farm or a redirection scheme. The ML_NYX_PDF_MALICIOUS heuristic further supports the malicious nature of the file. While no scripts were explicitly extracted, the structure of the PDF and the embedded URLs indicate an attempt to direct users to external, potentially malicious, content, likely as part of a phishing or malware distribution campaign.

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.
