MITRE ATT&CK

T1204 Malicious Link T1204.002 Malicious Link: Malicious File

The critical ClamAV detection 'Pdf.Exploit.Dropped-78' and the 'PDF_EMBEDDED_SCRIPT_PAYLOAD' heuristic indicate this PDF contains an embedded script designed to exploit vulnerabilities. The presence of XFA forms and embedded files further supports its malicious nature. The embedded script likely downloads and executes a second-stage payload.

Heuristics 5

ClamAV: Pdf.Exploit.Dropped-78 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Pdf.Exploit.Dropped-78
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.
