MITRE ATT&CK

T1204 Malicious File T1204.002 Malicious File: User Execution

The critical ClamAV heuristic firings, specifically 'Pdf.Exploit.Agent-36830', indicate the presence of a known PDF exploit. The PDF_EMBEDDED_SCRIPT_PAYLOAD heuristic further confirms that a script payload is embedded within the PDF stream, which is likely responsible for the malicious behavior. No document body text was available for analysis, but the embedded script and exploit signature strongly suggest an attack pattern aimed at exploiting PDF vulnerabilities.

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.
