MITRE ATT&CK

T1059.007 JavaScript T1203 Exploitation for Client Execution T1566.001 Spearphishing Attachment

The critical ClamAV detection and high ML heuristic indicate malicious intent. The presence of embedded JavaScript, identified by PDF_JAVASCRIPT and PDF_JS heuristics, strongly suggests the execution of malicious code. This JavaScript is likely responsible for downloading and executing a secondary payload, a common technique for PDF-based exploits.
