How do you impersonate a Windows virtual account using C++ and WinApi
To impersonate a Windows virtual account using C++ and WinApi, you can use the LogonUser
function to log on as the virtual account and obtain a security token, and then use the ImpersonateLoggedOnUser
function to impersonate the virtual account using the security token. Here's an example:
c++#include <windows.h>
#include <tchar.h>
#include <stdio.h>
int main()
{
HANDLE hToken = NULL;
if (!LogonUser(_T("VIRTUALACCOUNT"), _T("."), NULL, LOGON32_LOGON_SERVICE, LOGON32_PROVIDER_VIRTUAL, &hToken))
{
printf("LogonUser failed with error code %d\n", GetLastError());
return 1;
}
if (!ImpersonateLoggedOnUser(hToken))
{
printf("ImpersonateLoggedOnUser failed with error code %d\n", GetLastError());
CloseHandle(hToken);
return 1;
}
// Perform operations as the virtual account here
if (!RevertToSelf())
{
printf("RevertToSelf failed with error code %d\n", GetLastError());
CloseHandle(hToken);
return 1;
}
CloseHandle(hToken);
return 0;
}
In this example, we use the LogonUser
function to log on as the virtual account named "VIRTUALACCOUNT" with the LOGON32_PROVIDER_VIRTUAL
flag, which specifies that we want to log on using a virtual account. We then use the ImpersonateLoggedOnUser
function to impersonate the virtual account using the security token obtained from LogonUser
. Finally, we perform operations as the virtual account and then use the RevertToSelf
function to stop impersonating the virtual account.
Note that you will need to replace "VIRTUALACCOUNT" with the name of the virtual account you want to impersonate. Additionally, you may need to adjust the logon flags and parameters of the LogonUser
function to match your specific needs.
