Will Microsoft buy a domain msn.ru

In RuNet a very tasty domain is put up for sale - www.msn.ru. It turns out that since the late 90s it was occupied by a small software company. As they say in Internet.ru, the company sells the domain only with itself (that is, with a legal entity), and the most attractive offer was received from some Britons - $ 350 thousand. I wonder if Microsoft can sue a domain that matches one-on-one with its trademark MSN?
