T1204.002 Malicious File
The PDF file contains embedded script content, indicated by the PDF_EMBEDDED_SCRIPT_PAYLOAD and PDF_XFA_SCRIPT heuristics. This script is likely designed to download and execute a secondary payload, as suggested by the presence of an embedded file object. The XFA form further increases the risk by allowing executable scripts. The exact nature of the script's execution is not fully discernible due to potential obfuscation, but its presence strongly suggests a malicious intent to compromise the user's system.
Heuristics 4
-
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
