Seeing as this was the third attack in the last week, not to mention the zombie incident, the defences were well armed and ready to battle. The weapon system was now under control after an extensive challenge of getting the AMR offline, and the Anrufe were aware the moment the Narrikians began their attack. When the Anrufe noticed that the Narrikian attack was rebuilding their atmosphere, they decided to... Well... Do nothing. Shields would keep base energy from being absorbed, so all was perfectly well. The Anrufe structures were under-ground, and the planet was already now a boiling ocean due to the destruction of the atmosphere, so the Narrikian attacks did little.
On the other hand, Anrufe technology was not so easily hacked, seeing as how it was well encrypted -- especially seeing as the Mecherans had managed to get past the computer defences. The Anrufe had already beefed up their security. The Narrikians were only really helping the Anrufe. Any attacks that managed to hit the ocean floor would encounter soil shielding and the structure of the planet remained in tact.
