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

The PDF file exhibits a 'link farm' pattern, embedding a large number of external URLs. This technique is commonly used in phishing campaigns to direct users to malicious sites. The ClamAV detection as 'Pdf.Phishing.TtraffRobotInstall-7605656-0' further supports the phishing and redirection intent. No scripts were extracted from this sample, and the document body content is largely unreadable, making the URL analysis the primary indicator of malicious activity.

  • 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.
