Do you think the hacking of Nvidia's servers caused nicehash to have the right software?
Nobody hacked the Nvidia Servers, they are responsible for their own LHR unlock not any third party or hacker, they intentionally release or sell the hack to Nicehash because the GPU market has become very slow lately and now that LHR is unlocked many are buying LHR graphic cards they can find in stores.
