MITRE ATT&CK

T1059.001 JavaScript/JScript

The PDF file contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. A critical PDF_EVAL heuristic firing suggests the use of eval() for deobfuscation. The ClamAV detection name 'Pdf.Exploit.Agent-36118' further confirms its malicious nature. The embedded JavaScript likely downloads and executes a second-stage payload, exploiting a vulnerability within the PDF reader.
