MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF file contains embedded JavaScript with multiple eval() calls, indicating obfuscation and dynamic code execution. The ClamAV detection 'Pdf.Exploit.Agent-36118' and the 'PDF_JAVASCRIPT' and 'PDF_EVAL' heuristics confirm the presence of malicious JavaScript. The script's obfuscated nature suggests it is designed to download and execute a secondary payload, a common technique for initial access.
