Malware Insights
The PDF file exhibits characteristics of malicious intent, including an embedded script payload and XFA form usage, as indicated by the 'PDF_EMBEDDED_SCRIPT_PAYLOAD' and 'PDF_XFA' heuristics. ClamAV detections ('Pdf.Exploit.Dropped-78' and 'Pdf.Exploit.Agent-36809') further confirm its malicious nature. The embedded script is likely responsible for downloading and executing a second-stage payload, although its exact function cannot be determined due to obfuscation. The presence of an embedded URL suggests a potential delivery or command-and-control vector.
Heuristics 5
-
ClamAV: Pdf.Exploit.Dropped-78 critical CLAMAV_DETECTIONClamAV detected this file as malware: Pdf.Exploit.Dropped-78
-
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://www.xfa.org/schema/xfa-template/2.5/
