We dont know what it does, but tests show so far, the plugin works without any internet connection for very long, people have tested and put the computer clock on 2099 and the plugin still works, all this offline. One of the ip is unkno wn and is not in the legit dll, when you run N3. It is known a bit about the origin of the release as wrote:

So far no team has claimed this release, the original 'cracker' is unknown. (This could be done, because the original Reverser wanted to hide the changes in the plugin-dll and to prevent others from update it to newer versions.) We still dont know! The test which were done by different people here and other places show so far nothing suspicious. At the moment we have no proof that the release (windows) is safe, means it could be there is some malware code hidden, which we cant see with virustotal, since the binary is obfuscated by Themida/Code Virtualizer and thats why also this regkey is needed. The release is not safe in terms of having all ip adresses anf things patched, it does connect to some unknown amazon server, which is not the case for the legit Nexus3 Plugin. It is well worth to upgrade now from 3.4.4 on windows to this new version and finally enjoy the new XPs as they roll in. This release is fine, no need to block any ips, or take of any security.

So thank him for the license, as he is now in trouble with reFX. (i read this somewhere, cant find the source now!). It looks like the license was only supplied to VR for patching Nexus4, it was never intended to be included in the release. NOOOOO Requests in this thread! Remember AudioSex forum rules. So far no macOS release, but maybe someone can port it now with the legit dumped ('stolen') license. But you can of course simply report any problems here or well post any other stuff related Nexus4, like which XPs are still missing. This version uses a dumped license data, VR's installer pretty much does everything. Lets make one big thread about this! EDIT: Version 06-12-2022 07:41pm GMT Version v4.5.4 (win) by VR/ no macOS version now! 0.
