A recent warning shows that hackers are actively attacking older D-Link routers that no longer receive security updates. These routers are considered “end of life,” which means the manufacturer has stopped fixing security problems. Even though the device still turns on and provides internet, it is no longer protected. I wrote an article previously about other routers that had gone end of life, because you may have a different one that is no longer supported.
First, what is a router?
A router is the small box in your home that connects all your devices to the internet. Your phone, laptop, smart TV, doorbell camera, and even some appliances rely on it. Many people own one because it came with their internet service years ago or because they bought it once and never thought about it again.
That is exactly why these attacks work.
When a router reaches end of life, security flaws are never patched. Criminals know this and constantly scan the internet for older routers. When they find one, they can take control of it without the owner ever realizing it. From there, they may spy on activity, redirect web traffic, or use the router as part of larger attacks.
The recent attacks against older D-Link routers show how real this risk is. These devices have known weaknesses that are now being exploited in the wild. Most owners have no warning that anything is wrong.
This problem is so common that even I changed how I handle my own internet equipment. I now rent my router / modem from my internet provider because I got tired of my personal equipment going end of life or suddenly becoming unsupported. Renting means the provider is responsible for updates and replacements when technology changes.
What should you do?
Check the brand and model of your router, usually on a label on the bottom and search for the model name on the manufacturers website (e.g., https://dlink.com). If it is no longer supported, replace it.
This applies to other internet-connected devices too. If it no longer gets security updates, it is time to move on.
