Quite possibly. Apparently there are many pirate copies around in Russia. The best thing is to buy the game directly from this website. Although it'll take a week or two to arrive (about one week to the UK), at least you can be sure it's legit. The patches add so much to this game that it's well worthwhile. And of course, you can only play multiplayer (which is the really fun part IMHO) if you have the latest patch working.
