MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF file contains embedded JavaScript, indicated by multiple heuristic firings including PDF_JAVASCRIPT and PDF_JS. The ClamAV detection 'Pdf.Exploit.Agent-36014' strongly suggests a known exploit. The embedded JavaScript, although not fully detailed in the provided evidence, is the likely mechanism for delivering the exploit. The extracted file 'javascript_obj0013_001.js' and its associated heuristic signals like 'Script obfuscation indicators' further support this. The attack pattern is therefore a malicious PDF leveraging JavaScript to deliver an exploit.
