I have read about this news, and it was not even everyone who uses Binance who was sent that email. My old Binance address still exists, and it's still what I'm using on Segwit. I don't know why they select a few accounts and change their addresses, but whatever the case, maybe I will advise you to take it seriously. But even if you mistakenly still use your old address, your account can still be funded manually.
For the time being, the news is legit, but anything that has to do with sending this or that, please take note of that, as the address, which I know changes automatically by themselves, and you don't need to do anything to get it unless you open your account and generate the new Segwit address.
