MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF file contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. The unescape() function and the CVE-2009_4324 heuristic suggest the JavaScript is obfuscated and exploits a known vulnerability in PDF readers. The extracted javascript_obj0006_000.js artifact further supports the presence of malicious script. The primary intent appears to be the execution of this script, likely to download and execute a secondary payload, as suggested by the CVE-2009-4324 exploit.
