Of course Central bank of Russia would hire leading Russian security company to secure their network, who else they would hire? What's surprising in that? Of course leading politician may visit a company that is internationally known for its success, especially Medvedev who insisted on emphasizing the "modern hi-tech president" image. Cooperation between security researchers and cybercrime divisions of security services is also nothing new - what else security researchers would do with their findings? They can't prosecute computer criminals themselves... And of course they would get licensed by Russian security services - how else one could get government contracts, which in every country are not negligible source of income for many companies?
Making it sound as if pretty standard business practices and realities - which apply both to such undeniably corrupt country as Russia and to the US and to many other developed countries - as a sign of some ominous secrets is a journalistic malpractice. It may sound to somebody uninformed as there's something shady there - but in fact there's nothing in all that stuff. There might be secrets hidden somewhere - but Schachman findings are extremely weak in that regard.
