MITRE ATT&CK

T1059.001 PowerShell

The PDF file contains embedded and obfuscated JavaScript, indicated by the PDF_JS and PDF_JAVASCRIPT heuristics. The ClamAV detection Heuristics.PDF.ObfuscatedNameObject further supports the malicious nature of the obfuscation. The script likely attempts to download and execute a second-stage payload, though its exact function is obscured. The document body appears to be malformed or contains remnants of metadata rather than user-facing content.
