MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF file contains embedded JavaScript, a common technique for delivering malicious payloads. ClamAV detections of 'Win.Trojan.Agent-36166' strongly suggest malicious intent. The embedded JavaScript is likely responsible for downloading and executing a second-stage payload, although its exact functionality is obscured by obfuscation.
