There is a bunch of ways to buy this once you know the internet well enough.
Your best bet is going to be bitcoin. You can buy bitcoin for literally everything.
I bought steam wallet with my credit card which is in iraq so It is only supported in big company's and such(like steam, g2a) then traded that wallet for bitcoin on a website and then paid for this hack with it(still in process).
Even though I can't make paypal with my credit card, or use it on yandex.ru I had to rely on bitcoin which is useful tbh.
You could try a similar approach which suits you.
PS: I don't know russian, I am sorry(google translate ftw).
