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

The PDF contains a large number of external links, a technique commonly used in SEO poisoning attacks to drive traffic to malicious sites. The ClamAV detection as 'Pdf.Phishing.TtraffRobotInstall' further supports this. No scripts were extracted, and the document body was unreadable, but the link farm strongly indicates a phishing or malware distribution campaign.

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM

  • 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.
