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

The PDF file contains a large number of embedded URLs pointing to other PDF documents hosted on various domains. This behavior is indicative of a link farm or a mechanism to distribute malicious content or phishing lures. The ClamAV detection as 'Pdf.Phishing.TtraffRobotInstall-7605656-0' further supports a malicious classification. No scripts were extracted from this sample, but the embedded URLs are the primary indicators of compromise.

  • 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.
