MITRE ATT&CK

T1204.002 Malicious File Execution: Malicious File Execution

The PDF sample contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. The presence of a PDF_EVAL heuristic firing and a critical CVE_2009_4324 alert for media.newPlayer suggests the JavaScript is designed to exploit this vulnerability. The extracted JavaScript, though partially obfuscated, likely aims to download and execute a secondary payload. No specific family could be identified.
