I use the following…

It exist is PEPROCESS value.;

UCHAR buffer[256];
PTOKEN_GROUPS sid=(PTOKEN_GROUPS)&buffer[sizeof(TOKEN_GROUPS)];

ptoken=PsReferencePrimaryToken(exist);
status=ObOpenObjectByPointer(ptoken,0,NULL,TOKEN_ALL_ACCESS,NULL,KernelMode,&THandle);

ObDereferenceObject(ptoken);
//to give the Handle of Token

status = ZwQueryInformationToken(
THandle,TokenGroups,&buffer,sizeof(buffer), &requiredLength);
DbgPrint(“%d \n”,sid->GroupCount);
DbgPrint(“%d \n”,sid->Groups[0].Sid);
