The attack happens three missions after gaining the IFF, so to save most of the crew it is better to wait until most missions are done before getting the IFF. After it is installed, and the crew has been kidnapped you must IMMEDIATELY enter the Omega-4 relay in order to save everyone, otherwise there will be casualties.
