MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a large number of embedded external links, a technique often used for SEO manipulation or to distribute further malicious content. ClamAV detected this as Pdf.Phishing.TtraffRobotInstall, and an ML classifier also flagged it as malicious. The document body, though partially corrupted, contains text related to medical information, which may serve as a lure to disguise the malicious intent of linking to numerous external PDF files.

  • 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.
