MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF 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 malware attempting to hide its malicious actions, likely to download and execute a second-stage payload. The document body is unreadable, but the presence of JavaScript and the ClamAV signature are sufficient indicators of malicious intent.
