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 ClamAV detection 'Pdf.Exploit.Agent-36014' strongly suggests this is an exploit. The extracted JavaScript file, 'javascript_obj0013_001.js', shows signs of obfuscation, typical of malicious scripts designed to download and execute further payloads. The exact intent of the script cannot be fully determined due to obfuscation, but its presence within an exploit-carrying PDF points to a malicious execution chain.
