The PDF file contains embedded and obfuscated JavaScript, as indicated by the PDF_JAVASCRIPT and PDF_JS heuristic firings. ClamAV also flagged it with Heuristics.PDF.ObfuscatedNameObject, suggesting a deliberate attempt to hide malicious content. The JavaScript likely attempts to download and execute a second-stage payload, though its exact function cannot be determined due to obfuscation.
