MITRE ATT&CK
T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF file contains a large number of embedded URLs pointing to other PDF files, a technique often used for SEO manipulation or to distribute malware. The ClamAV heuristic also flags this as 'Pdf.Phishing.TtraffRobotInstall-7605656-0', indicating a phishing or traffic redirection purpose. No scripts were extracted, but the sheer volume of linked PDFs suggests a malicious intent to redirect 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.
