MITRE ATT&CK
T1059.001 PowerShell

The PDF file contains obfuscated JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. ClamAV also flagged it with Heuristics.PDF.ObfuscatedNameObject, suggesting a deliberate attempt to hide malicious content. The JavaScript likely executes a malicious payload, though its exact function cannot be determined from the provided evidence. The differential parser failure further supports the presence of obfuscation or malformation.
