Not only Russia, but the big part of ex-USSR as well. Typical device will feature an encrypted radio channel, protected from repeat and retranslation attacks. It will be hidden inside the car and use several immobilisation techniques. When an unauthorised engine start is detected it will spam the bus with signals to desync the connected devices and shut down the injection. Thieves can defeat that by bringing multiple pre-wired ECU and attaching them to the engine, transmission etc of the car getting stolen. As a counter measure the data connectors to these units are often rewired so that the unadulterated wiring won’t work. Then there will be a relay to break power to the fuel pump. This of course is defeated by hot-wiring the motor. Also mechanical locks are installed, the motor hood is reinforced etc. In isolation each of these measureas are rather easy to work around technically, but for the thief it’s usually easier to simply find an unprotected vehicle
