Hello,
is this a joke? Your mikrotik devices like the Chateau series routers have no admin password or wifi password at stock config.
You have to change the admin password fast and disable the wifi until you secured it also with a password.
But there is enough time for an attacker. I always look after reset if the logs are showing any other login than my computer is visible.
Every serious router manufacturer (for example AVM) has a secure router and wifi password at default.
Please fix it with newer firmwares.
Best regards
