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

The PDF document contains an embedded script payload, as indicated by the PDF_EMBEDDED_SCRIPT_PAYLOAD heuristic. ClamAV detections for 'Pdf.Exploit.Agent-6136306-0' and 'Js.Exploit.HTML-29' on an extracted artifact confirm its malicious nature. The XFA form suggests a potential exploit targeting Adobe's XML Forms Architecture. The embedded script is likely responsible for downloading and executing a second-stage payload.

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.
