MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. ClamAV detections confirm the malicious nature, identifying it as Win.Trojan.Agent-36166. The embedded JavaScript is likely responsible for downloading and executing a second-stage payload, although the specific actions are obfuscated. The file type and heuristic firings strongly suggest a malicious PDF designed for payload delivery.
