13 Internet Routers the FBI Says Are Vulnerable to Hacks

Why This Warning Matters

In a critical cybersecurity alert, the FBI has identified 13 legacy internet routers that are no longer supported by manufacturers—and are now actively targeted by hackers. If you’re using one of these models, your network could be wide open to ransomware, spying, or malware attacks.

This blog covers:

·         Which routers are at risk

·         Why these devices are dangerous

·         What steps you should take right now

Why Are These Routers a Threat?

Many of these devices are still in use by homes, small businesses, and even offices. However, because they’re no longer updated with security patches, they’ve become prime targets for cybercriminals who exploit outdated firmware to gain access.

In some cases, attackers are even building botnets using these routers, allowing them to launch larger-scale attacks using compromised networks.

The List: 13 Routers the FBI Flagged as Vulnerable

While the full list is being circulated through official security advisories and tech vendors, here’s a commonly reported list of legacy routers that are either end-of-life or known to have unpatched vulnerabilities:

1.       Cisco Small Business RV110W

2.     Cisco Small Business RV130

3.     Cisco Small Business RV215W

4.    D-Link DIR-655

5.     D-Link DIR-866L

6.     D-Link DIR-652

7.     Netgear WNR1000v3

8.     Netgear R6400 (older firmware)

9.     TP-Link TL-WR740N

10. TP-Link TL-WR841N

11.    Zyxel P660HN-T1A

12.  Linksys E1200

13.  Linksys WRT54GL

⚠️ Note: Even if your model isn’t listed, if your router is more than 5–7 years old and hasn’t received firmware updates, it could still be at risk.

What Makes These Routers Dangerous?

·         Outdated firmware means known vulnerabilities are unpatched

·         Default login credentials often remain unchanged

·         Remote access ports are sometimes left open by default

·         Exploits can be automated, letting hackers scan for and compromise devices at scale

In some cases, attackers can:

·         Redirect your traffic to malicious sites

·         Spy on your internet activity

·         Use your network to attack others

·         Spread malware to other devices on your network

How to Check If You’re at Risk

1.       Find your router model – Usually printed on the device or accessible via the router settings.

2.     Check the firmware version – Log in to your router's admin panel.

3.     Visit the manufacturer's website – See if updates are still being provided.

4.    Search for known vulnerabilities – Use databases like NVD or simply search your model + “CVE”.

What Should You Do If You Own One of These Routers?

✅ Option 1: Replace the Router

·         Best solution for security and performance

·         Choose models from trusted vendors that offer regular updates

·         Look for routers that support WPA3 encryption and automatic updates

✅ Option 2: Update Firmware (If Still Available)

·         Visit the official support page of the manufacturer

·         Follow update instructions carefully

·         Disable remote access and change default admin credentials

✅ Option 3: Add a Security Layer

·         Install a firewall or use network security tools

·         Use a VPN to reduce exposure of vulnerable hardware

Future-Proofing Your Home or Business Network

To stay safe long-term:

·         Schedule router firmware updates like you do with your phone or computer

·         Invest in modern routers with security-first features

·         Set strong, unique passwords for both your router and Wi-Fi

·         Segment smart home or IoT devices onto a separate network

Final Thoughts: Don't Ignore This Alert

The FBI’s warning isn’t theoretical—threat actors are actively exploiting these devices right now. Don’t assume you’re safe just because your internet is working.

Take this as a wake-up call to audit your home or office tech, secure your connections, and invest in reliable, up-to-date hardware.
