MITRE ATT&CK

T1059.001 PowerShell

The PDF file contains an embedded script payload, indicated by the PDF_EMBEDDED_SCRIPT_PAYLOAD heuristic. ClamAV detection as Pdf.Exploit.Dropped-78 further confirms its malicious nature. The embedded script is likely responsible for downloading and executing a second-stage payload, although its exact functionality is obscured by obfuscation. The presence of an XFA form also suggests a potential vector for exploit execution.

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.
