MITRE ATT&CK

T1204 Malicious File T1204.002 Malicious File: User Execution: Malicious Attachment

The critical ClamAV heuristic 'Pdf.Exploit.Dropped-81' indicates this PDF is designed to exploit vulnerabilities. The presence of embedded script payloads and multiple embedded files further supports its role as a dropper for malicious content. The exact nature of the payload is not discernible from the provided evidence, but the overall pattern points to a malicious PDF designed for exploitation.

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
