MITRE ATT&CK

T1059.001 PowerShell

The PDF contains embedded JavaScript, which is flagged by multiple heuristics including PDF_JAVASCRIPT, PDF_JS, and PDF_EVAL due to an eval() call. A machine learning classifier also identified the PDF as malicious with high confidence. ClamAV detected it as Pdf.Dropper.Agent-7596576-0. The embedded JavaScript is likely responsible for downloading and executing a second-stage payload, as indicated by the ML_NYX_PDF_MALICIOUS heuristic and the ClamAV signature.
