MITRE ATT&CK

T1059.001 PowerShell

The PDF file contains embedded JavaScript, as indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. The ClamAV detection 'Heuristics.PDF.ObfuscatedNameObject' further suggests malicious intent through obfuscation. The embedded JavaScript stream, named 'javascript_obj0011_000.js', is likely responsible for executing the malicious payload. The exact nature of the payload cannot be determined due to obfuscation, but the presence of JavaScript in a PDF commonly leads to further stages of infection.
