MITRE ATT&CK

T1203 Exploitation for Client Execution T1059.007 JavaScript

The PDF file contains XFA forms with executable scripts, flagged by multiple high-severity heuristics including PDF_EVAL and PDF_XFA_SCRIPT. ML classification and ClamAV detection strongly indicate malicious intent. The presence of embedded files and script obfuscation suggests the PDF is designed to download and execute a secondary payload, consistent with the ClamAV detection name 'Pdf.Exploit.Dropped-81'.

Heuristics 8

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
eval() call high PDF_EVAL

eval() found — commonly used for obfuscated exploit execution
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 script payload in PDF stream low 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.
Suspicious extracted artifact info EXTRACTED_FILE_STATIC_TRIAGE

One or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
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.
