MITRE ATT&CK

T1059.001 PowerShell

The PDF file contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. The CLAMAV_DETECTION heuristic identifies it as Pdf.Exploit.Agent-36014, suggesting it exploits known PDF vulnerabilities. The extracted artifact javascript_obj0013_001.js likely contains the malicious script responsible for the exploit, potentially downloading a second-stage payload. The obfuscation indicators within the extracted artifact further support this assessment.
