MITRE ATT&CK

T1059.001 PowerShell

The file is identified as malicious by ClamAV with the signature Win.Trojan.Agent-36166. Static analysis revealed embedded JavaScript, which is a common technique for delivering malicious payloads. The JavaScript action and embedded JS stream heuristics further support this. The document body is unreadable, but the presence of JavaScript and the ClamAV detection strongly suggest the file is designed to execute malicious code.
