MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF file contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. The ClamAV detection 'Pdf.Exploit.Agent-30083' strongly suggests this JavaScript is malicious and exploits a known vulnerability. The extracted artifact 'javascript_obj0015_000.js' is likely the malicious script responsible for further actions, such as downloading and executing a secondary payload. The obfuscation indicators further support this. The file's creation date and authoring application do not provide specific attribution.
