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. ClamAV also flagged it as Heuristics.PDF.ObfuscatedNameObject, suggesting malicious intent. The embedded JavaScript is likely responsible for downloading and executing a second-stage payload. While the document body is unreadable, the presence of JavaScript and the ClamAV detection strongly suggest a malicious PDF designed for code execution.
