MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF contains a large number of embedded links pointing to external PDF files hosted on various domains, consistent with SEO spam or a link farm used for distributing malicious content. ClamAV detection as 'Pdf.Phishing.TtraffRobotInstall-7605656-0' and ML classification further support its malicious nature. The document body itself appears to be obfuscated or corrupted, but the presence of numerous URLs is the primary indicator of malicious intent.

  • 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.
