When old hardware no longer receives updates, it becomes a security risk. That’s why even the FBI is now warning about Linksys routers.
Numerous modern devices today can establish an internet connection, allowing them not only to gain new functions but also to receive important security updates. Anything connected is constantly at risk of being attacked by cybercriminals. If such updates eventually stop, it becomes risky. This applies to laptops, smartphones, and routers. Many Linksys routers are now affected by this, prompting even the FBI to issue a warning.
Router Protection Is Often Neglected by Users
While it’s easier to keep track of important security updates on smartphones (such as through automatic updates that interrupt usage anyway), the situation is different for routers. Manufacturers typically provide regular updates for current models. However, their installation often occurs in the background—many users may not even be aware if their device still receives updates or not.
This situation poses a significant risk that criminals can exploit. According to the FBI, several older Linksys routers are particularly vulnerable due to a lack of updates. Moreover, there is reportedly malware circulating that is router-based and therefore not detected by any antivirus software.
The FBI Warns About These Linksys Routers
If you have one of the following routers, you should act quickly:
- E1200
- E2500
- E1000
- E4200
- E1500
- E300
- E3200
- WRT320N
- E1550
- WRT610N
- E100
- M10
- WRT310N
Well-known manufacturer calls for the disposal of certain routers
Important Update Available for Several Samsung Smartphones
Security Vulnerability Enables Secret Tracking of Bluetooth Devices
What Affected Users Should Do
As the U.S. intelligence agency explains, the perpetrators do not simply attack Linksys routers remotely. They also offer services like 5Socks and Anyproxy on the dark web, allowing others to access the vulnerable devices. At the same time, these services help them conceal their identity and location.

To avoid an attack, the FBI recommends purchasing a new Linksys router that still receives security updates. Alternatively, you should disable remote access and restart the device. You should also check beforehand whether the router is part of your network infrastructure.
It’s not the first time the manufacturer’s devices have been criticized. Back in 2019, a serious security flaw in Linksys routers came to light. TECHBOOK inquired about how the company informs its customers about the issue and what additional measures can be taken. However, a response has yet to be received.
