When most people picture a cyberattack, they imagine hackers overseas attacking companies head‑on. That’s no longer how many modern attacks work.
According to a recent advisory from the U.S. Cybersecurity and Infrastructure Security Agency (CISA), national and international partners, cyber attackers linked to China are increasingly compromising everyday internet‑connected devices like home routers, office Wi‑Fi equipment, cameras, network storage and other IoT (Internet of Things) devices and quietly using them to hide their cyber operations.
For small and home businesses, this matters more than you might think.
What’s really going on in plain English
Instead of attacking directly, these Chines state-sponsored bad actors:
- Break into thousands or even hundreds of thousands of unsecured devices
- Chain them together into hidden networks (often called “botnets”)
- Route hacking activity through those devices to mask where these attacks are actually coming from
This makes malicious traffic look like it’s coming from normal homes and small offices sometimes including businesses that have no idea they’re being used.
Why small and home businesses are especially at risk
Small organizations often:
- Use consumer‑grade routers
- Keep network equipment for many years beyond their “end of life” as they no longer receive updates or security patches by their manufacturers
- Delay firmware updates
- Don’t actively monitor network activity
The advisory notes that many compromised devices are out of date or no longer supported by the manufacturer, which makes them easy targets.
That doesn’t mean you’ll be “hacked” in the traditional sense, but your internet connection could be quietly misused.
What could happen if your device is compromised
Even if attackers aren’t targeting your data directly:
- Your network could be used to launch attacks on others
- Your IP address could be flagged or blocked by partners, banks, or service providers
- A future attack could move from your network into your systems
- You likely won’t see obvious warning signs at first
The most important steps you should take now
The good news: you don’t need an IT department to reduce this risk.
CISA’s guidance boils down to a few high‑impact actions:
- Replace old internet routers
If your router is more than 5–6 years old or no longer receives updates, replace it.
- Turn on automatic updates
Do this for routers, Wi‑Fi systems, computers, cameras, and any network‑attached storage.
- Change default passwords
Especially on routers, cameras, and any remote‑access tools.
- Use multi‑factor authentication (MFA)
Email, accounting, payroll, VPNs, and cloud services should always have MFA enabled.
- Remove what you don’t use
Old cameras, unused remote access software, or legacy VPN tools should be disconnected.
A simple rule to remember - If it connects to the internet and hasn’t been updated recently, it’s a risk.
Final takeaway
This advisory isn’t about sophisticated hacking it’s about basic digital hygiene.
Keeping your network devices current protects:
- Your business
- Your clients
- Your reputation
- And the broader internet ecosystem
