T1059.001 JavaScript/JScript
T1204.002 Malicious File
The PDF file contains embedded, obfuscated JavaScript, indicated by the PDF_XFA_SCRIPT and PDF_EMBEDDED_SCRIPT_PAYLOAD heuristics. This script is designed to execute arbitrary code, likely to download and run a secondary payload, as suggested by the embedded file artifact. The XFA form structure further supports the exploitation of PDF vulnerabilities.
Heuristics 5
-
XFA form contains risky executable script high PDF_XFA_SCRIPTPDF 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 script payload in PDF stream medium PDF_EMBEDDED_SCRIPT_PAYLOADPDF stream bytes contain an HTML/XFA <script> tag without accompanying Windows shell-execution primitives — common in accessible XFA forms but worth surfacing for analyst review.
-
Embedded file low PDF_EMBEDDEDPDF embeds a file attachment — could carry an executable or another weaponised document as a nested payload
-
XFA form low PDF_XFAPDF uses XML Forms Architecture — can contain script logic
-
