T1204.002 Malicious File
The PDF file contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. The ML classifier and ClamAV detection strongly suggest malicious intent. The obfuscated nature of the PDF, as suggested by ClamAV's 'ObfuscatedNameObject' detection, points towards an attempt to conceal malicious JavaScript execution, likely for exploiting a vulnerability or delivering a secondary payload.
