MITRE ATT&CK

T1059.001 JavaScript/JScript T1204.002 Malicious File

The PDF file contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. The critical CVE_2009_4324 heuristic specifically identifies a vulnerability related to media.newPlayer, which is likely leveraged by the embedded JavaScript to execute malicious code. The deobfuscated JavaScript, legacy_pdfkit_stage_000.js, suggests the script's purpose is to download and execute a second-stage payload. The confidence is high due to the specific exploit identified and the presence of obfuscated JavaScript.
