If you’ve noticed your internet connection lagging or devices in your home behaving strangely, it could be due to an outdated router.
The FBI recently issued a cybersecurity warning urging consumers to replace certain older routers that are no longer supported by manufacturers. These routers, many of which are older Linksys models, are highly vulnerable to cyberattacks.
The Dangers of “End-of-Life” Routers
The FBI’s warning, issued on May 7, highlights 13 specific router models that have reached the end of their life cycle. These routers no longer receive software updates or security patches, leaving them exposed to cybercriminals.
Many of these devices, popular in the 2000s and 2010s, are now being actively exploited by hackers. The lack of support from manufacturers makes them easy targets for malware and botnet attacks.
Once these routers are breached, attackers can install malicious software to remotely control the device. They can steal sensitive data, monitor network traffic, or even use the router to launch large-scale cyberattacks, such as denial-of-service (DoS) attacks or spam campaigns.
Some of the recent attacks have been linked to illicit proxy services like 5Socks and Anyproxy, which were seized by law enforcement.
List of Vulnerable Router Models
The FBI has provided a list of 13 specific router models that should be replaced as soon as possible. These include:
- Linksys E1200
- Linksys E2500
- Linksys E1000
- Linksys E4200
- Linksys E1500
- Linksys E300
- Linksys E3200
- Linksys WRT320N
- Linksys E1550
- Linksys WRT610N
- Linksys E100
- Linksys M10
- Linksys WRT310N
What to Do If You Have an Outdated Router
If you own any of these models, the FBI strongly recommends upgrading to a newer router that still receives regular firmware updates. Even if you disable the “remote administration” feature on your old device, this may not be enough to protect it, as hackers are becoming increasingly skilled at bypassing outdated security measures.
Signs Your Router Might Be Compromised
Malware infections on routers can be difficult to detect because the malicious software often resides directly in the router itself. Some signs that your router may be compromised include:
- Slower-than-usual internet speeds
- Unexpected device behavior or strange activity on your network
- Unusual data usage or network activity
If you notice any of these symptoms, it’s time to take action. The FBI advises rebooting your router and disabling remote access as a first step. However, the most effective solution is to replace the outdated router entirely with a more secure, modern device.
Reporting Suspicious Activity
If you suspect that your router or network has been compromised, the FBI encourages you to report it. You can contact your local FBI field office or visit the FBI website to file a report at www.fbi.gov/contact-us/field-offices.
