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

The PDF file contains a large number of embedded links pointing to external PDF files hosted on various domains. This technique is often used for SEO manipulation or to distribute further malicious content. The ClamAV heuristic 'Pdf.Phishing.TtraffRobotInstall-7605656-0' and the 'PDF_SEO_LINK_FARM' heuristic strongly indicate a phishing or traffic-driving campaign. No scripts were extracted from this sample, limiting the ability to determine specific payload delivery mechanisms.

  • 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.
