In 2026, the ordinary smart objects in our offices — from connected light bulbs to coffee machines — have become the soldiers of an invisible digital army. DDoS (Distributed Denial of Service) attacks have reached record volumes, capable of knocking out not only individual websites but entire portions of the internet's infrastructure. At Altanet Craiova we have seen local businesses left stranded for hours because their service providers were overwhelmed by fake traffic coming from thousands of compromised devices.
According to data provided by ECCU, the power of these attacks has grown thanks to the huge number of poorly secured IoT devices. What used to be a simple technical nuisance is today a weapon of economic blockade on a global scale.
What is a DDoS attack and how are IoT devices used?
A DDoS attack involves flooding a server or network with such a large volume of traffic that it can no longer process real requests. In 2026, attackers no longer use only infected computers, but "recruit" millions of Internet of Things (IoT) devices.
Consider the surveillance cameras, smart thermostats or network printers in your company. If they have factory-default passwords or outdated software, hackers can take control of them without you noticing. These devices are grouped into networks called "botnets" which, on a simple command, start sending data to a single target, blocking it completely.
Why are the DDoS attacks of 2026 more dangerous?
Technological evolution has given attackers new advantages that are hard to counter:
- Unprecedented traffic volumes: The move to 5G and 6G networks allows IoT devices to transmit data much faster, making attacks far more intense.
- Application-layer attacks: Hackers no longer just flood the internet "pipe", but simulate human behaviour to block specific website functions, such as the shopping cart.
- DDoS-as-a-Service: Anyone can now rent a botnet for a few dollars on the Dark Web, turning cyberattacks into an affordable commodity.
- Infrastructure targeting: Main internet nodes and DNS services are targeted, which can take web access down for entire regions.
How can you protect your digital infrastructure?
To stay online even during a massive attack, Altanet Craiova recommends a few critical measures:
- Securing IoT devices: Change the default passwords of all connected equipment and isolate them in a network separate from company data.
- Mitigation services: Use cloud solutions that can absorb and filter malicious traffic before it reaches your servers.
- Traffic monitoring: Implement systems that immediately detect abnormal traffic spikes and can activate protection automatically.
- Continuity plan: Prepare a static backup page to communicate with customers in case the main website becomes unavailable.
Conclusion
IoT devices make our lives easier, but they can become unwitting accomplices in blocking the global internet. In 2026, responsibility for security no longer falls only on the shoulders of server administrators, but on every user of smart technology. Protection against DDoS is today an investment in the stability of your business.
