MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.002 Malicious File

The PDF contains a large number of embedded URLs pointing to other PDF files, a technique commonly used for SEO manipulation or to distribute further malicious content. ClamAV identified this as Pdf.Phishing.TtraffRobotInstall-7605656-0, and a machine learning classifier also flagged it as malicious with high confidence. The document body appears to be corrupted or heavily obfuscated, preventing analysis of its specific content or intent beyond the link farm.

  • 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.
