We consider "they hacked the mobile network VPN's AND had time to reverse our protocol before being booted out of network" as too high a level to be resolved by us. If someone has enough resources to do this, he will also just hack into standard-level secured server at municipal office and there will probably be no one there to stop him or discover what went wrong.
