What began as a curious experiment quickly turned into a serious warning about the risks associated with the Internet of Things (IoT). An engineer and technology enthusiast decided to explore a simple idea: controlling his robot vacuum with a console command, turning a household task into a technological exercise. To do so, he analysed how the device communicated with cloud servers, even making use of artificial intelligence tools.

The result was unexpected. Without any intention of intrusion, he ended up accessing not only his own device but thousands of others across multiple countries. A flaw in the manufacturer’s system allowed an authenticated user to gain visibility over other devices, exposing sensitive information such as detailed home maps, technical data, and, most concerningly, real-time access to integrated cameras and microphones.

This episode highlights a structural problem: devices designed to increase comfort and efficiency can simultaneously introduce new attack surfaces. Furthermore, it demonstrates how critical vulnerabilities can exist for long periods without detection, and how they may be discovered entirely by accident, even before being exploited by malicious actors.

In a business context, this reality is even more significant. The proliferation of connected devices, from industrial sensors to smart equipment, greatly expands the risk perimeter. Security is no longer limited to traditional systems; it also depends on the robustness of devices that are often considered secondary.

This case raises an essential question: are we truly aware of the level of exposure introduced by the devices we use every day?

How can we protect ourselves?

• Ensure that devices and systems are designed with security principles from the outset;
• Segment networks, isolating IoT equipment from critical systems and sensitive data;
• Keep firmware and software up to date, reducing exposure to known vulnerabilities;
• Review permissions associated with sensors such as cameras and microphones, limiting their use wherever possible;
• Invest in security audits and vulnerability detection programmes, promoting a proactive approach.

In an increasingly connected world, cybersecurity cannot be an afterthought. It is a fundamental element in ensuring trust, continuity, and protection, both in personal and business contexts.
