That's especially funny that real passport data of high ranked security officer is available in leaked data and you can bribe you way into FSB's database of identity forms to get up to date info as well.
It's not same kind of investigation based on open info that bellingcat have done before.
You don’t have to bribe FSB directly to buy databases. You simply search among numerous online forums in .ru for a contact in Telegram, ask for a small sample, negotiate a price (100-10000 USD depending on database), pay for it with BTC, and obtain it via Telegram.
There was nothing FSB specific in the databases obtained by bellingcat, just regular citizen data.
It's not same kind of investigation based on open info that bellingcat have done before.
