MITRE ATT&CK
T1059.001 PowerShell T1204.002 Malicious File

The sample contains a Workbook_Open VBA macro that executes a PowerShell command. This command downloads a file from the URL https://nabhazena.org/content/slides/image/app/PROJECTTT.exe and saves it as C:\Users\Public\Documents\qrikeidcx.exe, then executes the downloaded file. This indicates a downloader or droppper functionality.
