MITRE ATT&CK

T1059.001 PowerShell

The PDF contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. The ClamAV detection 'Heuristics.PDF.ObfuscatedNameObject' further suggests malicious intent. The embedded JavaScript is likely responsible for executing malicious code, potentially downloading further payloads or exploiting vulnerabilities. The presence of XFA form elements (PDF_XFA) is also noted, which can sometimes be used in conjunction with JavaScript for exploitation.
