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

The PDF file contains a large number of embedded URLs pointing to external PDF documents, a technique commonly used for phishing or distributing further malware. The ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0' further supports a phishing or traffic redirection intent. The heuristic 'PDF_SEO_LINK_FARM' indicates a deliberate attempt to create a link farm, likely to manipulate search engine results or direct users to malicious content.

  • 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.
