T1203 Exploitation for Client Execution
T1566.001 Spearphishing Attachment
The PDF file contains embedded JavaScript, indicated by the PDF_JAVASCRIPT heuristic and the ML_NYX_PDF_MALICIOUS classification. ClamAV also detected it as Pdf.Exploit.Agent-35606. The JavaScript is likely responsible for exploiting a client-side vulnerability to execute code, which is a common method for downloading and running further malicious stages. No specific family could be identified, and no IOCs were directly extractable from the provided evidence.
