MITRE ATT&CK

T1204 Malicious Link T1059 Command and Scripting Interpreter

The PDF was flagged by multiple heuristics, including PDF_EMBEDDED_SCRIPT_PAYLOAD and PDF_XFA_SCRIPT, indicating the presence of executable script content within the document. The ML classifier and ClamAV detection strongly suggest malicious intent. The embedded script likely attempts to download and execute a second-stage payload, as indicated by the 'Dropped' designation in the ClamAV signature.

Heuristics 5

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
