MITRE ATT&CK

T1204 Malicious Link T1204.002 Malicious Link: Malicious File

The critical ClamAV detection 'Pdf.Exploit.Dropped-81' strongly indicates this PDF is designed to exploit vulnerabilities. The presence of embedded files and scripts further supports its role as a dropper or exploit delivery mechanism. The PDF structure itself does not contain readable content, suggesting its primary purpose is to host and deliver the malicious payload.

Heuristics 4

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
