T1059.001 PowerShell
T1059.005 Visual Basic
T1204.002 Malicious File
The sample is a macro-enabled Excel file that leverages VBA to execute a PowerShell command. The PowerShell command is heavily obfuscated but appears to download payloads from multiple URLs. The Workbook_Open macro and CreateObject calls indicate an auto-execution mechanism. The ClamAV detection and heuristic firings strongly suggest Emotet family activity.
