MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF file contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. The CLAMAV_DETECTION heuristic with the signature 'Pdf.Exploit.Dropped-94' strongly suggests this is a known exploit. The embedded JavaScript is likely responsible for downloading and executing a secondary payload, which is a common attack vector for PDF exploits. The file's metadata indicates it was created using Acrobat PDFMaker, but this is likely a benign artifact of the exploit's delivery mechanism.
