MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF file contains embedded JavaScript, indicated by multiple heuristic firings including PDF_JAVASCRIPT, PDF_JS, and PDF_EVAL. The `eval()` call within the JavaScript suggests code execution, and the presence of a JavaScript object file further supports this. The ClamAV detection as 'Pdf.Exploit.Agent-7200' confirms the malicious nature. The script likely downloads and executes a secondary payload, as is common with this type of exploit.
