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

The PDF file contains an embedded script payload and triggers XFA form heuristics, indicating an exploit attempt. ML classification and ClamAV detection confirm its malicious nature. The embedded script is likely responsible for downloading and executing a second-stage payload, as suggested by the PDF_EMBEDDED_SCRIPT_PAYLOAD heuristic.

  • XFA form low PDF_XFA
    PDF uses XML Forms Architecture — can contain script logic
  • Embedded URL info EMBEDDED_URL
