But yours assumes that Russia doesn't do counter-intel and wouldn't be looking for exactly these kinds of infiltrations. If it is obvious to us that these things would be targets, I'm pretty sure it is obvious to Russian intelligence services.
Bellingcat appear to routinely buy data from Russian blackmarket data brokers.
Replace 'buy' with 'receive' and 'Russian blackmarket data brokers' with 'intelligence assets' and you're correct.
Shady fly by night data hosting doing counter-intel, or better, Putin spending his precious rubles on running counter-intel ops for shady fly by night hosting companies, are both hilarious.
Russian govt has always held counter intel to be a top priority and they devote an enormous amount of resources towards it, so why is that hilarious?
