MITRE ATT&CK

T1059.001 PowerShell T1059.007 JavaScript

The PDF file contains embedded JavaScript with multiple eval() calls, indicating obfuscation and dynamic code execution. The ClamAV detection 'Pdf.Exploit.Agent-36118' strongly suggests a known exploit. The JavaScript is heavily obfuscated, but the presence of eval() and the ClamAV signature point towards the execution of malicious code, likely a downloader for further stages.
