MITRE ATT&CK

T1204 Malicious File T1204.002 Malicious File: User Execution

The critical ClamAV detection 'Pdf.Exploit.Agent-36830' strongly indicates this PDF is malicious. The presence of an embedded script payload and an embedded file further supports this. The file likely exploits a known PDF vulnerability to execute the embedded payload, leading to a malicious outcome.

Heuristics 6

ClamAV: Pdf.Exploit.Agent-36830 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Pdf.Exploit.Agent-36830
ClamAV detection on extracted artifact critical EXTRACTED_FILE_CLAMAV

ClamAV flagged at least one file extracted from inside this sample. Even when the wrapping document carries no AV detection of its own, a hit on the carved artifact is a strong indicator the sample is a delivery vehicle.
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.
