T1059.001 PowerShell
T1204.002 Malicious File
T1059.005 Visual Basic
The Workbook_Open macro is configured to execute a PowerShell command. This command is constructed by concatenating strings and is designed to download a second-stage executable from 'http://18.209.1.250/22/QPL-51000302711.exe' and save it as 'C:\Users\Public\Documents\concernmeet.exe'. The macro also writes this command to a file named 'C:\Users\Public\apersone.czmd' before executing it via ShellExecuteW. The use of ShellExecuteW and the download/execution pattern strongly indicate a downloader functionality.
