NovaTech Innovations is a medium-sized tech firm specializing in smart home devices. With over 150 employees, they have recently launched a new line of smart thermostats and have built an accompanying app for remote access and control.

The Breach

Several customers started reporting unauthorized adjustments to their home temperatures and some even noticed unexpected spikes in their energy bills. Upon investigation, NovaTech discovered that their app had been compromised, giving hackers control over the smart thermostats of about 15,000 customers.


An internal review revealed that an older version of their app had inadequate security measures. A junior developer had inadvertently left a set of debugging APIs (Application Programming Interfaces) exposed, which provided backdoor access to control the devices without needing user authentication.


Financial Loss

Many customers demanded reimbursements for the unexpected spikes in their energy bills caused by unauthorized thermostat adjustments.

Reputational Damage

News of the breach spread quickly in tech circles, leading to a decline in sales and mistrust in NovaTech’s commitment to security.

Operational Hurdle

The company had to temporarily suspend the app, forcing customers to manually adjust their thermostats and reducing the product’s appeal.


Immediate Fix

NovaTech rolled out an urgent app update that removed the exposed APIs and enhanced security measures.


The company sent out emails to all affected customers, explaining the situation, apologizing, and outlining steps taken to prevent future breaches.


NovaTech offered a month’s credit to affected customers and extended their device warranty by an additional year.

Internal Review

The company started regular internal security audits and training sessions for employees to raise awareness about cybersecurity best practices.
