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 'Pdf.Exploit.Agent-36066' strongly suggests this JavaScript is malicious and exploits a known vulnerability within PDF viewers. The embedded JavaScript is likely responsible for downloading and executing a second-stage payload. Due to the lack of readable document body text and obfuscated script content, the exact payload and delivery mechanism cannot be definitively determined.
