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

The PDF file contains a large number of embedded external links, as indicated by the PDF_SEO_LINK_FARM heuristic. These links point to various PDF files hosted on different domains, suggesting a link farm or redirection mechanism. The ClamAV detection as 'Pdf.Phishing.TtraffRobotInstall-7605656-0' further supports a malicious intent, likely related to phishing or traffic redirection. The document body content is largely unreadable due to encoding issues, but the presence of numerous external links is the primary indicator of malicious activity.

  • 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.
