jade.wtf

I am absolutely shocked that the initial encryption key is literally the md5sum of "ubnt".

I wonder what the folks at HostiFi (cloud hosted UniFi controller software) might be thinking right now...

Thanks for sharing our response. I expect this to be fixed by Ubiquiti, but it will probably take some time, so we have that mitigation process available for those interested.
