MITRE ATT&CK
T1059.001 PowerShell T1204.002 Malicious File

The PDF file contains an XFA form and an embedded JavaScript payload, as indicated by the PDF_XFA and PDF_EMBEDDED_SCRIPT_PAYLOAD heuristics. ClamAV detections confirm this, identifying it as Pdf.Exploit.Agent-6136306-0 and Js.Exploit.HTML-29 on an extracted artifact. The embedded script is likely responsible for executing the exploit, leading to the malicious verdict. The embedded URLs are related to XFA specifications and do not appear to be directly malicious.

Heuristics 5

  • ClamAV: Pdf.Exploit.Agent-6136306-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Pdf.Exploit.Agent-6136306-0
  • 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.
  • 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.
