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

The PDF file contains a large number of embedded URLs pointing to other PDF files hosted on various domains. This behavior is indicative of a link farm or a distribution mechanism for further malicious content, as suggested by the 'Pdf.Phishing.TtraffRobotInstall' ClamAV detection. The document body itself is heavily obfuscated and does not provide clear textual lures. No scripts were extracted from this sample.

  • 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.
