MITRE ATT&CK
T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF file contains a large number of external links, many of which point to other PDF files hosted on suspicious domains. The ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0' and the PDF_SEO_LINK_FARM heuristic indicate a phishing or malicious redirection attempt. The document body, while containing garbled text, also includes URLs that are likely part of the lure. The primary attack pattern involves redirecting users to malicious content disguised as a user manual.

  • 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.
