T1204.002 Malicious File
T1566.002 Spearphishing Attachment
The PDF file utilizes XFA forms, a known vector for exploitation. Critical heuristics indicate embedded script payloads and ClamAV detections (Pdf.Exploit.Agent-6136306-0 and Pdf.Exploit.Agent-36769) confirm its malicious nature. The embedded script is likely responsible for delivering the exploit payload.
Heuristics 5
-
ClamAV: Pdf.Exploit.Agent-6136306-0 critical CLAMAV_DETECTIONClamAV detected this file as malware: Pdf.Exploit.Agent-6136306-0
-
ClamAV detection on extracted artifact critical EXTRACTED_FILE_CLAMAVClamAV 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_PAYLOADPDF 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.
-
XFA form low PDF_XFAPDF uses XML Forms Architecture — can contain script logic
-
Embedded URL info EMBEDDED_URLOne 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.URL http://ns.adobe.com/xdp/
