I just tried this on Chrome 56 in Windows, and it’s not immune. However the “Real Domain Name” extension did its job.
It's good to know that if you know to install that extension you could be protected if you were using Chrome V.56. I wonder how many users are using it? Does it also intercept you going to the site and warn you, before arriving there, or do you have to pro-actively look at the URL address bar and actually notice you aren't where you are supposed to be?
Still, the problem here is that there are Russian Cyrilic alphabet characters that look almost exactly like the English alphabet characters and would be very difficult to distinguish using your "Real Domain Name" extension. For example the Russian "R" looks exactly like an English "P" while a Russian Cyrillic lower case "g" looks very much like the English lower case "r" and a Russian "S" is a "C". These letters can be exchanged in a Domain name and you could be none the wiser, unless you looked very, very closely, if they had constructed their Domain name very carefully to mimic the correct one.
As the MacDailyNews take put it using all Cyrillic characters: Ⅼеτ’ѕ Ье ϲагеғυⅼ оυτ τһеге. ⋃ѕе а геаⅼ Ьгоѡѕег!
