T1059.001 PowerShell T1059.005 Visual Basic

The VBA macro contains a CreateObject call and references PowerShell, indicating it's designed to execute commands. The script reconstructs a PowerShell command that downloads and executes a VBScript from the URL 'http://ag.mnalbivra.net/admin/predictors.vbs', saving it as 'notepad.vbs' in the temp directory. This is a common downloader pattern.
