T1059.001 PowerShell
The PDF contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. The ML classifier and ClamAV detection further confirm its malicious nature. The embedded JavaScript is likely responsible for executing malicious code, potentially downloading further payloads or exploiting vulnerabilities. The specific intent of the script could not be fully determined due to obfuscation, but its presence is a strong indicator of malicious activity.
