T1204.002 Malicious File
The PDF file contains embedded executable scripts, indicated by the PDF_EMBEDDED_SCRIPT_PAYLOAD and PDF_XFA_SCRIPT heuristics. Machine learning classification strongly suggests maliciousness. The embedded file 'embedded_file_obj0008.bin' is likely the payload. The XFA form suggests a complex exploit targeting PDF rendering.
Machine Learning
- Nyx PDF Classifier malicious score 1.0000
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
-
