MITRE ATT&CK

T1059.001 PowerShell

The PDF file contains embedded JavaScript with multiple eval() calls, indicating obfuscation and malicious intent. The ClamAV detection 'Pdf.Exploit.Agent-36118' strongly suggests exploitation. The JavaScript is heavily obfuscated, but the presence of eval() and string concatenation points towards dynamic code execution, likely for downloading and executing further malicious content. No specific family could be identified due to the obfuscation.
