MITRE ATT&CK

T1204.002 Malicious File

The PDF file contains embedded script payloads within XFA forms, as indicated by multiple high and critical heuristic firings. This suggests the document is designed to execute malicious code upon opening. The ClamAV detection 'Pdf.Exploit.Dropped-81' further confirms its malicious nature. While the specific payload is not detailed, the presence of executable scripts within the XFA structure points to an exploit delivery mechanism.

Heuristics 6

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.
ClamAV: Pdf.Exploit.Dropped-81 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Pdf.Exploit.Dropped-81
Embedded script payload in PDF stream medium PDF_EMBEDDED_SCRIPT_PAYLOAD

PDF 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_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
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.
