MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.007 JavaScript

The PDF contains a large number of embedded URLs pointing to external PDF files, triggering a critical heuristic for a link farm. ClamAV also detected this as Pdf.Phishing.TtraffRobotInstall. The embedded URLs suggest a phishing or SEO manipulation campaign, where the document acts as a lure to external malicious content. No scripts were extracted, but the nature of the embedded URLs indicates a high likelihood of malicious intent.

  • 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.
