T1059.001 PowerShell
T1204.002 Malicious File
T1059.005 Visual Basic
The Workbook_Open macro is designed to execute a PowerShell command. This command constructs a URL to download a second-stage executable from 'http://3.120.146.69/bg/40652000016.exe' and saves it as 'C:\Users\Public\Documents\deepwall.exe'. The macro also attempts to create a file 'C:\Users\Public\dssdd.cm' which contains the PowerShell command. The use of ShellExecuteW and the Workbook_Open auto-execution strongly indicate malicious intent.
