MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF exploits CVE-2009-4324, CVE-2009-0927, and CVE-2007-5659 by embedding and executing JavaScript. The extracted JavaScript files, particularly legacy_pdfkit_stage_000.js, legacy_pdfkit_stage_001.js, and legacy_pdfkit_stage_002.js, indicate a multi-stage process likely involving the download and execution of further malicious content. The presence of multiple critical vulnerability firings suggests a sophisticated exploit chain.
