Half Baked IoT Stove Could Be Used As A Remote Controlled Arson Device | Hackaday
You could burn half of Islington down![Pen Test Partners] have found some really scary vulnerabilities in AGA range cookers. They are connected by SMS by which a mobile app sends an unauthenticated SMS to the AGA to give it commands for instance preheat the oven, You can also just tell your AGA to turn everything on at once.
The problem is with the web interface; it allows an attacker to check if a userís cell phone is already registered, allowing for a slow but effective enumeration attack. Once the attacker finds a registered device, all they need to do is send an SMS, as messages are not authenticated by the cooker, neither is the SIM card set up to send the messages validated when registered.
