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 of a known PDF vulnerability. The JavaScript is heavily obfuscated, but the presence of eval() and string concatenation points towards dynamic code execution, likely to download and execute a secondary payload. No specific family could be identified due to the obfuscation.
