Security updates are critical to keeping your digital life protected—something most of us have internalized over years of using phones, PCs, and other internet-connected devices. But while attention often falls on major platforms like Windows or Android, your home router is just as important—if not more so. Now, the FBI’s Cyber Division has issued a stark reminder: if you’re still using an outdated router, it’s time to replace it.
In a recently issued Flash alert (PDF), the FBI warns that several older routers are being actively targeted in malware campaigns and coordinated attacks. The routers in question are no longer receiving firmware or security updates, making them vulnerable to known exploits. The affected models include several from Linksys, such as the E1000, E1200, E1500, E1550, E3200, E4200, and the WRT series (WRT310N, WRT320N, WRT610N). Also named are Cisco’s Valet M10 and Cradlepoint’s E100 and E300.
If any of these names ring a bell, the safest move is to retire the device. While replacing a router might feel like an unwelcome expense—especially if it’s still technically working—the reality is that unsupported hardware is a glaring security risk. These routers no longer receive security patches and have become soft targets for hackers deploying botnets and remote access exploits.
Even if your specific router isn’t listed, the FBI recommends logging into your router’s web interface to check its firmware version and ensure that it’s up to date. A quick online search using your model number should tell you whether it’s still supported. If updates have stopped, that’s your cue to start shopping for a replacement. As frustrating as it may be, staying secure means keeping up with hardware lifecycles too.
