MITRE ATT&CK

T1059.001 PowerShell

The PDF file contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. The presence of a PDF_EVAL heuristic firing suggests that the JavaScript is being used to execute arbitrary code, likely to download and run a second-stage payload. The ClamAV detection of 'Pdf.Exploit.Agent-36118' further confirms its malicious nature. The script appears to be obfuscated, making a precise determination of its actions difficult, but the overall pattern points to a typical exploit delivery mechanism.
