MITRE ATT&CK

T1059.001 PowerShell

The PDF contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. ClamAV detected the file as Heuristics.PDF.ObfuscatedNameObject, suggesting malicious obfuscation techniques are in use. The embedded JavaScript likely performs malicious actions, such as downloading a second-stage payload, but its exact function is obscured. The presence of XFA form elements (PDF_XFA) is also noted.
