MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file contains a large number of embedded external links, identified by the PDF_SEO_LINK_FARM heuristic, suggesting a link farm or redirection scheme. The ClamAV detection as 'Pdf.Phishing.TtraffRobotInstall-7605656-0' and the ML classifier's high confidence further indicate malicious intent, likely for phishing or distributing further malware. No scripts were extracted, but the sheer volume of links points to a coordinated effort to direct users to potentially harmful content.

  • 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.
