MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a large number of embedded external links, many of which point to other PDF files. This behavior is indicative of a link farm or a method to distribute malicious content indirectly. ClamAV detection as 'Pdf.Phishing.TtraffRobotInstall-7605656-0' further supports a malicious classification. No scripts were extracted, but the structure suggests a potential phishing or content distribution scheme.

  • 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.
