In 2026, modern offices are full of connected devices. From smart bulbs to high-end coffee machines, everything is connected to the internet. However, these objects (IoT) are often ignored by the security department. At Altanet Craiova we have noticed that precisely this equipment is becoming an "open door" for hackers. It offers a simple access route to the rest of your company's network.
According to Kaspersky data, attacks on IoT devices have risen alarmingly. Many of these objects are designed for comfort, not for safety. They run simplified operating systems that are hard to protect. Once compromised, a single sensor can allow the attacker to monitor all the data traffic in the office.
Why are IoT devices such easy targets?
Most smart objects come with minimal security settings. In 2026, many users still keep the factory passwords. This information is public and easy for attackers to find. What is more, these devices do not receive regular security updates. A vulnerability discovered today can remain unpatched for years.
Hackers use automated scanners to find exposed IoT equipment. They are not necessarily looking to control your thermostat. Their goal is to find an entry point into the network. From there, they can spread to the servers that hold your financial data. A simple smart bulb can thus become the origin of a major cyber disaster.
The major risks of unprotected smart objects
IoT infrastructure brings specific vulnerabilities to the corporate environment:
- Default passwords: Hackers can take control instantly using the manufacturer's standard credentials.
- Lack of encryption: Many devices send data over the network in clear text, which is easy to intercept.
- Uncontrolled access: IoT equipment is often placed on the same network as the company's critical servers.
- Unauthorised monitoring: Surveillance cameras or assistants' microphones can be used for industrial espionage.
How can you secure the IoT ecosystem in your office?
To reduce the risks, Altanet Craiova recommends an isolation strategy. You can protect your business by applying a few simple rules:
- Network segmentation: Create a separate network (VLAN) just for smart objects. They must not be able to communicate directly with the company's servers.
- Changing passwords: Do not leave any device with its factory settings. Use complex passwords for every piece of equipment.
- Auditing equipment: Remove smart objects that no longer receive support from the manufacturer. Their security can no longer be guaranteed.
Conclusion
In 2026, the Internet of Things brings efficiency, but also new risks. Smart objects are useful gateways, but hackers can use them too. Only through careful monitoring can you benefit from the technology without exposing your sensitive data. The safety of your office starts with the smallest connected sensor.
