MITRE ATT&CK

T1059.001 Command and Scripting Interpreter: PowerShell

The PDF file contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. The presence of a high-severity PDF_EVAL heuristic suggests that the JavaScript code is likely obfuscated and uses an eval() call to execute arbitrary code. The ML classifier also strongly indicates maliciousness. The primary attack pattern involves leveraging JavaScript execution within the PDF to download and execute a secondary payload.
