MITRE ATT&CK
T1059.001 PowerShell

The PDF file was flagged for containing a link to a known malicious redirector. This indicates the document is likely part of a phishing or malware distribution campaign. No scripts were extracted, and the document body was unreadable, so the primary indicator is the malicious URL.

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.
