MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF file contains embedded JavaScript, indicated by the 'PDF_JAVASCRIPT' and 'PDF_JS' heuristics. ClamAV detection 'Pdf.Exploit.Agent-36066' further confirms its malicious nature. The presence of JavaScript suggests an attempt to exploit vulnerabilities within the PDF reader to execute code, likely to download and run a second-stage payload. The document body was not parsable, so the rationale is based on the heuristics and detection name.
