MITRE ATT&CK
T1204.002 Malicious File: User Execution
T1059.007 Command and Scripting Interpreter: JavaScript
The PDF file contains XFA (XML Forms Architecture) which is known to be a vector for exploits. Heuristics indicate the presence of XFA heap spray exploit code and embedded script payloads. ClamAV also detected this as Pdf.Exploit.Dropped-78. The exploit likely aims to download and execute a second-stage payload, although no specific URLs or script content were directly extractable for further analysis.
Heuristics 7
-
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.
-
XFA JavaScript heap-spray exploit code critical PDF_XFA_HEAP_SPRAYPDF contains XFA script content with heap-spray or shellcode-like JavaScript markers such as large encoded word sequences, util.pack, large arrays, or spray variable names. This is a weaponised Adobe Reader exploit pattern, not a normal interactive form.

ClamAV: Pdf.Exploit.Dropped-78 critical CLAMAV_DETECTIONClamAV detected this file as malware: Pdf.Exploit.Dropped-78
-
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
-
Embedded URL info EMBEDDED_URLOne 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.URL http://ns.adobe.com/xdp/
