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

The PDF file contains a large number of embedded external links, a technique commonly used for SEO poisoning or phishing. The ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0' and the heuristic 'PDF_SEO_LINK_FARM' strongly indicate a phishing or malicious redirection attempt. The document body, though partially corrupted, mentions 'Beneficios del tratado de libre comercio peru ee uu', suggesting a lure related to trade agreements to entice users to click the embedded links.

  • 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.
