The PDF file contains an embedded script payload, as indicated by the PDF_EMBEDDED_SCRIPT_PAYLOAD heuristic and the presence of an embedded artifact. ClamAV detection further confirms its malicious nature. The embedded script is likely responsible for downloading and executing a second-stage payload, contributing to the overall attack.
