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

The PDF file contains a large number of embedded URLs, disguised as a parts list, which is a common lure for phishing or malware distribution. The heuristic 'PDF_SEO_LINK_FARM' specifically indicates a mass external PDF link farm, suggesting the primary purpose is to redirect users to other malicious PDF documents. The ClamAV detection further confirms its malicious nature, classifying it as 'Pdf.Phishing.TtraffRobotInstall'.

  • 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.
