MITRE ATT&CK
T1204 Malicious Link T1059 Command and Scripting Interpreter T1059.007 JavaScript/JScript

The PDF file contains an XFA form with a risky executable script, indicated by the PDF_XFA_SCRIPT heuristic. This script is likely designed to exploit vulnerabilities within the XFA form processing to download and execute a secondary payload. The presence of an embedded URL further supports the malicious intent, suggesting a delivery mechanism for additional malicious content.

Heuristics 5

  • XFA form contains risky executable script high CVE related PDF_XFA_SCRIPT
    PDF embeds an XFA form whose script block contains exploit, submission/launch, or shell-execution primitives. Ordinary LiveCycle print/update scripts are left as generic XFA/JS signals unless stronger behavior is present.
  • Embedded file low PDF_EMBEDDED
    PDF embeds a file attachment — could carry an executable or another weaponised document as a nested payload
  • XFA form low PDF_XFA
    PDF uses XML Forms Architecture — can contain script logic
  • AcroForm button with action trigger low PDF_ACROFORM_BUTTON
    PDF contains a /Btn form field together with a SubmitForm/URI/Launch/JS trigger — this is the building block of fake 'Download' or 'Open' button overlays used in PDF phishing lures
  • 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.
