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

The PDF file contains a large number of embedded external links, a technique commonly used in phishing and SEO spam campaigns to distribute malicious content. The heuristic 'PDF_SEO_LINK_FARM' and the ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0' strongly indicate a phishing or malware distribution intent. The document body, while containing some obfuscated text, also includes these links, reinforcing the lure.

  • 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.
