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

The PDF file contains a link to a known malicious redirector, indicating a likely attempt to lure the user to a harmful website. The file was generated by wkhtmltopdf, a tool often used for creating PDFs from web content, suggesting it might be part of a phishing or malware distribution chain. No scripts were extracted, limiting further analysis of the payload.

Heuristics 2

  • PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK
    PDF contains a clickable URI to redirector infrastructure used by a known malicious PDF SEO/adware delivery campaign. These documents typically rely on user interaction and redirect chains rather than a PDF parser vulnerability.
  • 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.
