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 likely serve as a link farm to redirect users to malicious sites. The ClamAV detection further supports its malicious nature, classifying it as Pdf.Phishing.TtraffRobotInstall. No scripts were extracted from this sample, and the document body contained only chemical information unrelated to the 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.
