MITRE ATT&CK

T1059.001 PowerShell

The PDF file contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. The ClamAV detection Heuristics.PDF.ObfuscatedNameObject further suggests malicious obfuscation. While the JavaScript content is truncated, its presence and the obfuscation point to an attempt to execute malicious code, likely to download a second-stage payload or exploit a vulnerability. No specific family could be identified due to the limited analysis of the script.
