MITRE ATT&CK

T1059.001 PowerShell T1204.001 Malicious Link

The PDF file contains embedded JavaScript, identified by the PDF_JAVASCRIPT and PDF_JS heuristics. The critical CVE_2007_5659 heuristic indicates the exploitation of a known vulnerability related to JavaScript execution within PDF documents. The presence of deobfuscated JavaScript files (legacy_pdfkit_stage_000.js, legacy_pdfkit_stage_001.js) suggests that the script is designed to download and execute a secondary payload. The ClamAV detection further confirms its malicious nature.
