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

The PDF contains a large number of embedded external links, identified as a PDF link farm. This technique is often used to manipulate search engine rankings or to redirect users to malicious sites. While no scripts were explicitly extracted, the presence of numerous external links suggests a potential for further malicious activity, such as downloading additional payloads or phishing attempts. The ClamAV detection as 'Pdf.Phishing.TtraffRobotInstall-7605656-0' further supports a phishing or traffic redirection motive.

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM

  • 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.
