T1204.002 Malicious File: Malicious JavaScript

The PDF file was flagged as malicious by multiple engines, including ClamAV which identified it as 'Pdf.Exploit.Agent-36388'. Static analysis revealed embedded JavaScript, indicated by 'PDF_JAVASCRIPT' and 'PDF_JS' heuristics. An extracted JavaScript artifact was also detected by ClamAV as 'Js.Exploit.HTML-27'. This suggests the PDF is designed to exploit vulnerabilities through JavaScript, likely leading to the download or execution of a secondary payload.
