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' strongly suggests a known exploit is present. The JavaScript is heavily obfuscated, but the presence of eval() and the heuristic firings point to an attempt to download and execute a secondary payload, a common tactic for malware delivery.
