MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.002 Malicious Link

The PDF contains a large number of embedded links to external PDF files hosted across numerous domains. This technique, identified by the PDF_SEO_LINK_FARM heuristic, is often used for SEO manipulation or to distribute malicious content. The ClamAV detection as Pdf.Phishing.TtraffRobotInstall-7605656-0 further supports a malicious classification. No scripts were extracted, and the document body content is heavily obfuscated and does not provide clear user-facing lures.

  • 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.
