MITRE ATT&CK

T1059.001 PowerShell T1204.001 Malicious Link

The PDF file contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. The presence of an eval() call and the CVE-2009-4324 exploit (media.newPlayer) strongly suggest that the JavaScript is intended to be executed to exploit this vulnerability. The extracted JavaScript files, though obfuscated, likely contribute to downloading and executing a second-stage payload. The confidence is high due to the clear exploit and script execution indicators.

Heuristics 5
