T1059.001 JavaScript/Shell Script Execution: JavaScript Execution
T1204.002 Malicious File: User Execution: Malicious File
The PDF sample contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. A critical PDF_EVAL heuristic firing suggests the use of eval(), which is commonly used to deobfuscate and execute malicious JavaScript. The reconstructed JavaScript string `unescape(unescape(escape(this.info.title)))` is indicative of obfuscated code execution. This pattern suggests the PDF is designed to exploit a vulnerability to run arbitrary code, likely downloading a second-stage payload.
