MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF was flagged by a malicious redirector heuristic, indicating it contains a link to known malicious infrastructure. The ML classifier also strongly indicated maliciousness. While no scripts were explicitly extracted, the PDF structure and embedded link suggest an attempt to redirect the user to a harmful site, likely for phishing or malware delivery.

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.
