MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF document contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. The critical CVE-2009-4324 heuristic specifically points to the use of media.newPlayer to trigger the exploit. The deobfuscated JavaScript, legacy_pdfkit_stage_000.js, likely downloads and executes a second-stage payload. The DOC BODY content appears to be obfuscated code fragments rather than user-readable text.
