T1105 Ingress Tool Transfer
The Document_Open VBA macro is designed to execute a malicious payload. It constructs a batch file at C:\Users\Public\Documents\god.bat which then uses PowerShell to download an executable from http://coachcarmenwilliams.com/RFQ012.exe and save it as C:\Users\Public\Documents\leastalready.exe. The macro then attempts to execute this downloaded file. The script also attempts to establish persistence by writing to the registry key HKCU\Software\Microsoft\Windows\CurrentVersion\Run\IAccessible2Proxy.
