MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.007 JavaScript

The PDF contains a large number of embedded external links, a technique often used for SEO manipulation or to host malicious content. ClamAV detected this as Pdf.Phishing.TtraffRobotInstall, and an ML classifier also flagged it as malicious. The document body, though partially corrupted, contains references to "Neutrogena hydro boost sheet mask review" and lists numerous URLs, reinforcing the link farm heuristic.

  • 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.
