MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF file contains embedded JavaScript, indicated by multiple heuristic firings including PDF_JAVASCRIPT and PDF_JS. The ClamAV detection 'Pdf.Exploit.Agent-36014' further confirms its malicious nature. The embedded JavaScript file, 'javascript_obj0013_001.js', shows signs of obfuscation and hex escape sequences, suggesting it is designed to perform malicious actions such as downloading and executing a second-stage payload. The lack of readable document body text prevents a more specific determination of the lure, but the technical indicators point to a PDF exploit.
