Heuristics 3

  • UNC path in PDF — possible NTLM credential theft (CVE-2018-4993/CVE-2019-7089) high CVE likely CVE_2018_4993
    PDF contains a UNC path (\\server\share) alongside action triggers — when a vulnerable viewer resolves this path, Windows may send NTLM credentials to the remote host as the matching PDF action is processed
  • Remote GoTo action high PDF_GOTO_REMOTE
    PDF references an external document via GoToR/GoToE whose target is a URL, UNC path, or executable
  • 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.
