MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The file is a PDF containing an embedded script payload, as indicated by the PDF_EMBEDDED_SCRIPT_PAYLOAD heuristic and ClamAV detection (Pdf.Exploit.Agent-6136306-0). The presence of XFA form elements (PDF_XFA) suggests a potential vector for exploit delivery. The embedded script is likely responsible for downloading and executing a secondary payload from a remote source, although the exact script functionality is not fully detailed in the provided evidence. The embedded URL is likely part of the exploit chain.

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.
