In France, hackers disrupted refrigeration systems at hundreds of supermarkets. The consequences were immediate: unusually high temperatures, spoiled merchandise, and significant financial losses.
This time, cybercriminals weren’t targeting bank accounts or confidential documents. They went after the equipment responsible for keeping food safe.
But if hackers can interfere with supermarket refrigeration systems, what could stop them from targeting the smart coffee machine in your office?
It might sound like an unlikely scenario. Yet it raises a very real cybersecurity concern.
A Wi-Fi-enabled coffee machine may have its own software, login credentials, and remote-control features. If it contains an exploitable vulnerability, it could become a target itself or, under certain circumstances, an entry point into other systems.
And this isn’t entirely hypothetical. In 2020, an Avast security researcher demonstrated how a smart coffee machine could be compromised, disrupted, and made to display a ransom message.
From commercial refrigerators to office coffee machines, the lesson is the same: any connected device can potentially become part of your organization’s attack surface.
Printers, surveillance cameras, smart thermostats, televisions, alarm systems, and industrial equipment all make business operations more convenient. But when poorly secured, they can also introduce vulnerabilities.
The real question is no longer simply whether your computers are protected.
It’s how many other devices are connected to your network—and whether someone could take control of them.
In France, Hackers Targeted the Cold Chain
During the night of October 11–12, 2026, a cyberattack disrupted refrigeration installations at numerous French supermarkets, including stores operated by Intermarché and Coopérative U.
As reported by Le Devoir and Le Journal de Montréal, the incident highlights an often-overlooked vulnerability: connected equipment can become a target for cybercriminals, with consequences extending far beyond IT systems.
According to initial reports, the attackers may have exploited remote-control systems to interfere with refrigeration equipment, including its defrost cycles.
Temperatures reportedly reached 50°C (122°F) in some locations, compromising food storage conditions.
The consequences included discarded inventory, temporarily unusable equipment, and urgent technical interventions.
Early reporting also mentioned refrigeration controllers associated with manufacturer Danfoss. However, the precise intrusion methods and vulnerabilities involved have not been fully established publicly.
What makes this incident particularly concerning is that the attackers did not need to physically destroy the equipment to cause real-world damage.
Manipulating how the systems operated may have been enough.
Every Connected Device Can Become a Potential Entry Point
When we think about cyberattacks, computers, servers, and email accounts usually come to mind.
Yet a company’s network often includes far more devices than its employees or management realize.
Consider a typical Quebec small or medium-sized business. Beyond computers and smartphones, its network might include:
- Multifunction printers connected to the office network.
- Surveillance cameras and video recording systems.
- Smart thermostats and HVAC equipment.
- Alarm systems and electronic access controls.
- Smart televisions and video conferencing equipment.
- Industrial machinery and automated controllers.
- Refrigeration and environmental monitoring systems.
- Even a connected coffee machine.
These devices are part of what is commonly called the Internet of Things, or IoT.
Each may have its own software, security settings, credentials, and network connections.
A connected device isn’t inherently dangerous. But one that is poorly secured, forgotten, or exposed to the internet can become a weak point in an otherwise well-protected business.
Some devices still use default passwords. Others no longer receive security updates. Some offer remote administration interfaces that business owners may not even know exist.
The risk doesn’t come from connected technology alone. It comes from how that technology is installed, maintained, and integrated into the business network.
Even Your Office Coffee Machine Could Become an Entry Point
Your office coffee machine probably isn’t the first device your IT manager thinks about during a cybersecurity assessment.
Yet some smart models connect to Wi-Fi, receive software updates, or support remote control.
Like other connected devices, they can contain vulnerabilities.
And the risk isn’t purely theoretical.
In 2020, Avast security researcher Martin Hron demonstrated that a smart coffee machine could be compromised, causing it to malfunction and display a ransom demand.
His research was published under the title The Fresh Smell of Ransomed Coffee.
Importantly, this was a controlled security research demonstration—not an actual attack against a business.
There’s another distinction worth making: compromising a coffee machine does not automatically give an attacker access to company computers or sensitive information.
However, if a vulnerable device shares a network with critical business systems, and appropriate network protections are missing, it could potentially serve as a starting point for a broader intrusion.
The problem isn’t the coffee. It’s everything businesses connect to their networks without necessarily asking whether those devices are secure.
A coffee machine, printer, or smart thermostat should not have unrestricted access to the same resources as a computer used for accounting or customer records.
That’s why device inventories and network segmentation matter.
The next time someone brings a new smart device into the office, the question shouldn’t simply be, “Will it connect to our Wi-Fi?”
It should also be: “Do we really want to give this device access to our business network?”
Could an Ordinary Printer Put Your Business at Risk?
A network printer may seem harmless compared with a server containing confidential information.
But many printers have embedded operating systems, administration interfaces, and access to the company network.
If an attacker exploits a vulnerability, they may be able to access certain information or attempt to move toward other systems, depending on the device’s configuration and network permissions.
The same principle applies to surveillance cameras, smart thermostats, and industrial controllers.
It’s important to distinguish between two types of risk.
First, the connected device itself becomes the target.
That’s what the French supermarket incident illustrates. By interfering directly with equipment operations, attackers can cause property damage, interrupt business activities, or create potentially dangerous conditions.
Second, the device becomes an entry point into the broader network.
A vulnerable device can sometimes provide a foothold for attackers attempting to reach other systems, particularly when the network isn’t properly segmented.
In either case, the resulting damage can far exceed the value of the compromised device.
Why Do Connected Devices Often Fall Outside Cybersecurity Oversight?
Part of the answer lies in how businesses manage their equipment.
Computers are typically installed, configured, and monitored by an internal IT team or a managed IT service provider.
But what about everything else?
Surveillance cameras may be installed by a security company. HVAC systems are maintained by building automation specialists. Commercial refrigeration equipment is configured by refrigeration contractors.
Each provider is responsible for its own area of expertise.
Problems arise when no one has clear responsibility for the cybersecurity of these connected systems.
A contractor may require remote access for maintenance. The IT team may be unaware that this access exists. Management may assume that everything is properly secured.
These gaps in coordination create blind spots that cybercriminals can exploit.
Equipment lifespan is another challenge.
A business may operate an HVAC system or industrial machine for 15 or 20 years. But the software controlling that equipment may not receive security support for nearly as long.
As a result, a device can remain fully operational while running software that is no longer secure.
Antivirus, Firewalls, and Microsoft 365: Why They Aren’t Enough
A small business may have invested in professional antivirus software, reliable backups, advanced email protection, and multifactor authentication.
These are essential cybersecurity measures.
But they don’t automatically protect every connected device on the network.
Unlike traditional computers, many smart devices don’t support conventional antivirus software. Their security depends instead on proper configuration, firmware updates, access controls, and network architecture.
A properly configured firewall can restrict dangerous communications, but it cannot replace a complete inventory and effective management of connected equipment.
That’s why cybersecurity needs to cover the entire business network—not just its computers.
Five Practical Steps to Protect the Devices You Might Be Overlooking
1. Identify Every Connected Device
Do you know exactly how many devices are using your business network?
Your inventory should include not only computers but also printers, cameras, controllers, building systems, and other smart equipment.
For each device, document its manufacturer, model, maintenance provider, and any existing remote access.
2. Review and Secure Remote Access
A vendor doesn’t necessarily need permanent remote access to your equipment.
Identify which systems can be reached from the internet and prioritize secure access methods, including strong authentication wherever supported.
Administration interfaces should not be publicly exposed unless there is a clear operational need.
3. Separate Connected Equipment From Your Main Network
Network segmentation divides your infrastructure into separate security zones.
For example, surveillance cameras, printers, and building systems can be placed on dedicated networks with tightly controlled communications.
If one device is compromised, segmentation helps limit an attacker’s ability to reach other systems.
4. Check for Updates and Outdated Equipment
Connected devices need security updates, too.
Ask your vendors whether your equipment is still supported and whether firmware or software updates are available.
When a device can no longer be patched, additional safeguards may be necessary, such as network isolation or replacement.
5. Include Connected Devices in Your Cybersecurity Plan
The security of smart equipment shouldn’t be left entirely to the vendors who install it.
Your IT team or managed service provider should know these devices exist, understand how they connect, and participate in assessing their risks.
For business-critical equipment, establish contingency procedures as well. These might include manual operation, independent monitoring, emergency technical contacts, and business continuity plans.
Are Quebec Businesses Prepared for This Type of Threat?
The incident in France should encourage Quebec businesses to look at their technology environments differently.
A restaurant could lose inventory if its refrigeration system is disrupted. A manufacturer could be forced to halt production if an industrial controller becomes unavailable. A retailer could experience operational problems if its access control or surveillance systems stop working.
These scenarios don’t mean that every connected device is easy to hack.
They demonstrate that equipment often considered secondary can play a critical role in business operations.
And as businesses increasingly automate their processes, they need a clearer understanding of how their physical equipment depends on their IT infrastructure.
Protecting connected devices is therefore about more than cybersecurity.
It’s also about business continuity, operational resilience, and protecting your bottom line.
Your Next Cybersecurity Threat Might Not Come Through a Computer
The French supermarket incident is a reminder that cybercriminals can target far more than files, passwords, or financial information.
Connected equipment is now everywhere in modern businesses. These devices streamline operations, improve efficiency, and make everyday processes smarter.
But every new connection deserves scrutiny.
Just because a device is working properly doesn’t mean it’s secure. And just because it doesn’t look like a computer doesn’t mean it can’t be hacked.
