We count on our home WiFi to power everything from streaming to smart devices.

But according to a new FBI alert, some of those routers are quietly doing something else—working for cybercriminals.

If your device is on the list, your network might already be compromised.



The FBI has issued a flash warning about a dangerous malware called TheMoon, which is spreading through outdated home routers.

These infected devices are being turned into proxy servers—tools hackers use to commit crimes while hiding behind your personal internet connection.

Even worse, the FBI says these attacks don’t always require a password. Many older routers are being scanned remotely, with malware slipping in through open ports and other vulnerabilities.

The FBI says the infected routers are being linked to international cyberattacks, some allegedly involving state-sponsored groups.

The targeted routers—is yours on the list?​

The FBI has confirmed that the following end-of-life models are actively being exploited. That means they’re no longer supported with security updates—and they’re especially vulnerable.

Linksys models:

• E1000
• E1200
• E1500
• E1550
• E2500
• E300
• E3200
• E4200
• WRT310N
• WRT320N
• WRT610N

Cradlepoint model:

• E100

Cisco model:

• M10

If you’re still using any of these devices, it’s time to take immediate action.

What’s the risk to your household?​

An infected router can be used as a disguise by hackers for doing illegal crimes like launching cyberattacks and data theft.

You may even be held liable or investigated if your IP address is connected to illegal activity.

How to know if you’re compromised​

The signs of a hacked router can be hard to detect. Here are some red flags:

• Overheating: Device feels warm even when idle
• Sluggish connection: Slow downloads or frequent disconnections
• Unknown devices: You see unfamiliar items connected to your network
• New admin accounts: Someone may have taken control of your settings
• Changed configurations: Features toggled on/off without your input

What to do right now?​

Identify your router model: Look at the sticker on the bottom or back of your device. If it matches any from the list above, you’re at risk.

Replace your router if possible: The most effective step is to upgrade to a modern router with ongoing security support. Many newer models come with better speed, parental controls, and protection.

If replacement isn’t an option yet, install the latest firmware from the manufacturer’s website. Change your passwords for both WiFi and router login. Disable remote access to block hackers from logging in.

Reset your router and manually reconfigure settings. Monitor your online accounts for suspicious login.
