MITRE ATT&CK
T1059.001 PowerShell

The PDF file contains obfuscated JavaScript, as indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. ClamAV also flagged it as Heuristics.PDF.ObfuscatedNameObject. The obfuscated JavaScript likely attempts to download and execute a second-stage payload, a common technique for PDF-based malware delivery. Due to the obfuscation, the exact execution flow and payload are not discernible from static analysis alone.
