MITRE ATT&CK

T1059.001 PowerShell

The file is a PDF document with embedded JavaScript, identified by heuristics as a potential attack vector. ClamAV detections indicate it is a known trojan, specifically 'Win.Trojan.Agent-36166'. The embedded JavaScript, although large, is the primary mechanism for the malicious activity, likely downloading and executing a secondary payload.
