MITRE ATT&CK

T1059.001 JavaScript/JScript T1059.007 JavaScript/JScript T1204.002 Malicious File

The PDF file contains embedded JavaScript, including calls to eval(), indicating an attempt to execute arbitrary code. The ClamAV detection 'Pdf.Exploit.Agent-36118' strongly suggests a known exploit. The embedded JavaScript is heavily obfuscated, but the presence of eval() and script actions points to a malicious payload execution. The extracted artifact 'javascript_obj0013_000.js' is likely part of this obfuscated payload.
