Most business owners have enough to worry about without wondering whether the thermostat in the conference room is a cybersecurity risk.
You’ve got computers to maintain, employees to manage, customers to serve, and a business to run. The security cameras keep an eye on the building, the printer handles the paperwork, and the smart TV in the conference room makes presentations a little easier. These devices are supposed to make life simpler, not create another IT headache.
But there’s a catch. Every device connected to your network is another potential doorway for a security threat OR another cause of frustrating network problems.
The Next Cybersecurity Problem May Be Sitting on Your Desk
A recent warning from AI company Anthropic has raised concerns about the potential for AI-powered malware to spread between internet-connected devices, including inexpensive smart TVs and other Internet of Things (IoT) equipment.
In experiments described in BleepingComputer, researchers explored whether small AI models could be distributed across inexpensive devices and configured to run on different hardware. Basically, they found that a few IoT devices (in this case, “off-brand” Android TV boxes) could muster enough computing power to run AI, AND that, under simplified conditions, an AI agent could replicate itself across those devices.
Now, what it did not find was the ability for that agent to replicate under real-world conditions and across devices…BUT the folks running the experiment expect that could come as soon as the end of 2026.
Alright, what does this mean for you practically? It means that all those little IoT devices in your work environment – the thermostat, the security cameras, and yes, even the fridge – are actually vulnerability points in your network.
And now, AI-assisted attacks could eventually become more adaptable, helping malicious software figure out how to operate on unfamiliar devices and potentially spread to others. Devices that were never designed to handle sophisticated security threats could become part of a much larger attack.
Your Business Has More Connected Devices Than You Think
Think about what’s connected to your business network today.
You’ve got the computers and phones your employees use every day. But what about the printer that scans documents directly to a shared folder? The security cameras that you check from your phone? The smart thermostat controlled through a vendor’s cloud service? The conference room equipment, access-control system, or other connected devices installed over the years?
Here’s another one that often gets overlooked: equipment installed by third-party vendors.
Your phone system provider installs a device to manage your phones. Your copier vendor connects a multifunction printer to the network. A security company installs cameras or an access-control system. Each vendor knows their own equipment, but that doesn’t necessarily mean they understand your network, the other devices connected to it, or the potential consequences of their installation.
Sometimes, the problem isn’t a sophisticated cyberattack. It’s a device that’s been installed without the proper coordination. This is a common problem we see, which is often extremely difficult to locate.
For example, a phone system or copier vendor might connect equipment that’s configured to hand out IP addresses through its own DHCP server. If that device starts assigning addresses to computers and other equipment on your network, it can conflict with your legitimate network services and cause connectivity problems. Employees may suddenly lose access to the internet, shared drives, or business applications, and tracking down the cause can be a frustrating exercise.
These are often called rogue DHCP servers. The term “rogue” doesn’t necessarily mean the device is malicious. It means an unauthorized or unintended DHCP server is handing out network configuration information where it shouldn’t. What this means for your business is simple: connectivity headaches.
And that’s just one example. A vendor-installed device could also introduce unnecessary remote access, weak passwords, outdated firmware, or network connections that give it more access than it needs.
These devices often get less attention than computers because they seem relatively harmless. They do a specific job, they usually keep doing it, and nobody wants to spend time messing with something that isn’t broken.
That’s precisely where the trouble can begin.
A device may be running outdated firmware, using a default password, or relying on security settings that nobody has reviewed since installation. Worse, nobody may know who is responsible for updating it, monitoring it, or checking whether it’s communicating with systems it has no business accessing. In fact, most of the time, no one in the business knows they are there, including the IT folks.
Four Things SMB Owners Should Do Now
You don’t need to unplug every smart device in the building or turn your office into a government security facility. You do need to make sure someone is paying attention.
- Find out what’s connected. Start with an inventory of the devices on your network. Include printers, cameras, phone systems, access-control equipment, wireless devices, and other connected hardware. You can’t secure what you don’t know exists.
- Coordinate third-party installations. Make sure your IT provider or Internal IT knows when a phone, copier, security, or other vendor plans to connect equipment to your network. Vendors should understand the network requirements before installation, and somebody should verify that the new equipment is configured correctly afterward. Don’t assume that because a vendor knows its own equipment, it knows what’s best for your network.
- Keep devices updated and control access. Devices should not be running on factory passwords or unnecessary open services. Use strong, unique credentials wherever supported, disable features you don’t need, and establish who is responsible for firmware updates. Pay particular attention to devices that no longer receive security support.
- Keep smart devices away from critical systems. Where your equipment supports it, separate IoT devices from the computers, servers, and business data that matter most. A camera may need to communicate with its recording system, but it usually has no reason to communicate with your accounting computer. Network segmentation can help limit the damage from misconfigured or compromised equipment. Network segmentation means your security cameras, copier, phone system, and other connected devices don’t automatically get the same level of access as your business computers. If one device is compromised or misconfigured, the goal is to keep that problem from spreading across the entire network.
Don’t Wait for the Next Big Threat
Cybersecurity has a way of turning ordinary business equipment into tomorrow’s security headline. But not every network problem starts with a sophisticated hacker or a breakthrough in artificial intelligence. Sometimes it starts when a vendor plugs something in, assumes everything is fine, and leaves without considering the bigger picture.
The smart devices in your office should make your business more efficient, not give attackers an easy way in or bring your network to a halt. As threats evolve, the fundamentals still matter: Know what’s connected, coordinate installations, keep devices updated, control what they can access, and make sure somebody is responsible for the whole picture.
