This JSON request instructs the alarm clock on every “alarmSound” event to send a HTTP request to the coffee machine. Whilst this may seem a simple and effective way of implementing the Pub/Sub pattern in HTTP, this poses a significant security risk.
By not being able to validate if the receiver of the subscribed message wants the message or not, there is effectively a DDOS vulnerability. An attacker with the ability to set subscriptions on the alarm clock can effectively send HTTP messages to any device or internet property they want. If this is done across enough devices, a DDOS vulnerability is created.
Toast popping out of a toaster or a car driving across a road traffic sensor could be the trigger of a future large scale DDOS against a web property.

So…exactly how many times a day are you singing Happy Birthday to your sink? Unless you’re among the most germaphobic among us, it’s unlikely you ever thought the simple act of handwashing would start to take on such a central role in our daily lives. Of course, with all the touching and such, bar soap […]
Paralysis by analysis. It’s the phenomenon that happens when you’re so stuck on thinking through all the ramifications of your actions that you don’t actually take action in the first place. That can happen with all this free time you’re spending stuck inside your house. With literally every home-bound option available to you, it’s easy […]
At this point, it’s every single person’s responsibility to reduce their own carbon footprint and transition to a more sustainable lifestyle. But if you consider the grim fact that the biggest culprit of greenhouse gas emissions from human activities in the U.S. is burning fossil fuels for electricity, things, like pivoting to metal straws and […]
