Dark web monitoring: does it put your data at risk?
NEWYou can now listen to Fox News articles!
You hear the phrase “dark web monitoring,” and it can feel unsettling. If a company is scanning shady corners of the internet for your information, are they exposing you even more?
That question comes up often. In fact, Joyce from Florida wrote in with a concern many people share:
“When companies scan the dark web for your data, doesn’t that put you at risk? Your information is now out there. Please explain what that really means.” Joyce, Fanning Springs, Fla.
Joyce, great question. A lot of people assume these services are pushing your data somewhere new. That isn’t what is happening. The short answer is simple. No, dark web monitoring does not put your information at risk. Let’s walk through what is really going on.

What is dark web monitoring and how does it work
These services are not uploading your data anywhere. They are not spreading your information.
Instead, they are:
- Monitoring known data breach dumps, hacker forums and leaked databases
- Searching for matches to your information, like your email or phone number
- Alerting you if your data is already found there
Here is the key point to understand. Your information is already out there before they ever find it.
Does dark web monitoring expose your data? A simple way to think about it
The simple answer is no. Think of it like checking if your stolen credit card is being used. No one is putting your card out there.
A monitoring service watches for signs that your data is already in use, so you can shut it down quickly.
10 SIGNS YOUR PERSONAL DATA IS BEING SOLD ONLINE
How dark web monitoring works without exposing your information
Reputable services use secure methods to check for your data. They are designed to protect your information during the process.
These include:
- Hashed searches, where your data turns into unreadable code before checking
- Secure databases and APIs that compare data without exposing it
- Monitoring existing breach datasets instead of live personal accounts
They are not:
- Logging into your accounts
- Posting your information
- Interacting with criminals on your behalf
That distinction matters. They are observers, not participants.
Dark web monitoring can help users respond quickly by changing passwords, freezing credit or locking down affected accounts. (Kurt “CyberGuy” Knutsson)
When dark web monitoring could put your data at risk
While the concept itself is safe, the provider you choose matters. There can be a risk if:
- You use an unknown or untrusted service
- A company asks for sensitive documents without a clear reason
- The service itself has weak security and gets breached
That is why it is important to stick with well-known providers that have a strong track record.
BE AWARE OF EXTORTION SCAM EMAILS CLAIMING YOUR DATA IS STOLEN
Why dark web monitoring is actually helpful
Without monitoring, you might never know your data was exposed. That means:
- Your email and password could be circulating for months
- Someone could open accounts in your name
- Your information could be resold again and again
With monitoring, you get an early warning. That gives you time to change passwords, lock accounts and stop fraud before it spreads. In many cases, that early alert is the difference between a close call and a major financial hit.
Ways to stay safe from data breaches and identity theft
Even with monitoring, you should take simple steps to protect yourself.
1) Limit how much data is out there
Use a data removal service to reduce your exposure over time. A data removal service works to remove your personal data from data broker sites. That reduces how much of your information is circulating online in the first place. Check out my top picks for data removal services and get a free scan to find out if your personal information is already out on the web by visiting Cyberguy.com
2) Stick with trusted services
Choose an identity theft protection service with strong security practices and clear privacy policies. They monitor your personal information and alert you quickly if it appears in breaches or suspicious activity. They also include identity theft protection tools in one place. See my tips and best picks on Best Identity Theft Protection at Cyberguy.com

3) Watch for alerts and act quickly
If you get a breach alert, change your password right away. Avoid reusing passwords across accounts. A password manager can help. Check out the best expert-reviewed password managers of 2026 at Cyberguy.com
THE ONE THING SCAMMERS CHECK BEFORE TARGETING YOU ONLINE
4) Turn on two-factor authentication
Two-factor authentication (2FA) adds an extra layer of protection, even if your password is compromised.
5) Freeze your credit if needed
A credit freeze can stop criminals from opening new accounts in your name without your approval.
6) Monitor your financial accounts regularly
Check your bank and credit card statements often to catch suspicious activity early.
Kurt’s key takeaways
Dark web monitoring does not expose your data. It checks whether your data has already been exposed. Think of it as a radar system. It scans for danger so you can respond before things get worse. In a world where data breaches are common, that kind of early warning can make all the difference.
If your personal data was already out there right now, would you want to know or stay in the dark? Let us know by writing to us at Cyberguy.com

Fox has announced that it’s acquiring Roku outright, in a deal that values the streaming company at $22 billion.
The deal will see Fox’s TV networks and Tubi streamer combine with Roku’s network of streaming devices, smart TV software, and The Roku Channel. The companies say in a press release that by combining they’ll become the third-largest player in the US TV industry by viewing share.
It doesn’t sound like the plan is to build Roku and Fox into a walled ecosystem. Roku founder and CEO Anthony Wood, who will stay on in the company and join Fox’s board of directors, said in an investor call that Roku “will continue to operate as an open, partner-friendly platform supporting the entire streaming ecosystem.” As for Fox, the press release says the companies are “committed” to the “continued ubiquitous distribution” of Fox’s own content.
”This is a defining moment for Fox, and a natural extension of the deliberate and focused strategy we have been executing for nearly a decade,” Fox CEO Lachlan Murdoch said in a statement. “Today, we take the next step: bringing together the most valuable live content portfolio in video consumption with the preeminent streaming platform through which America watches it.”
“Over the past two decades, we’ve built Roku into the leading TV streaming platform, reaching more than 100 million households globally and reshaping how people discover and enjoy entertainment,” said Roku CEO Wood. “I’m incredibly proud of what our team has built, and the combination with Fox is an extraordinary opportunity to accelerate our vision, scale faster and innovate more aggressively for viewers, partners and advertisers.”
The deal is expected to close in the first half of 2027, but remains subject to regulatory approval, which in the current climate seems unlikely to pose a problem in the US.
Update, June 15th: Added Anthony Wood quote from the investor call.
Last year, the FBI opened a Cyber Range in Huntsville, Alabama, for simulating cyberattacks. Think of it sort of like the famous Hogan’s Alley, but for modern digital crime training. It’s a massive 22,000 square-foot replica of an entire town, complete with a convenience store, gas station, hospital, and even fully furnished houses.
It’s a training facility where the bureau can recreate real-world scenarios for training and research purposes. All of the various buildings and facilities are hooked up the way they would be in a real town. There’s even a small data center with over 200 servers that can be hacked, infected with malware, and studied. But, importantly, all of the systems in the fake town are cut off from the outside world, which means there’s no danger of any malicious code or anything from escaping containment.
Students practice performing forensic investigations on car entertainment systems, hospital computer networks, and corporate security systems. They can see how various cyberattacks might affect power grids or spread through home networks.
While the facility opened last year, the FBI only shared a video this week, giving the public its first glimpse inside.

Your Wi-Fi router may be the least glamorous gadget in your home. It sits on a shelf, blinks in the corner and only gets attention when Netflix freezes. However, that little box controls a lot more than you may think.
The FBI and Justice Department say a Russian military intelligence hacking group abused vulnerable small office and home office routers to help run an espionage operation. The group is known as APT28, Fancy Bear and Forest Blizzard. It has been linked to Russia’s GRU military intelligence agency.
The hackers changed router settings so internet requests could flow through servers they controlled. That gave them a way to watch for valuable targets, redirect traffic and steal sensitive login information. The Justice Department and FBI say they disrupted the U.S. portion of the network in April. That is good news. Still, law enforcement cannot walk into your house, update your router or change the password printed on an old sticker. That part is on you.

FBI WARNS OF HACKERS EXPLOITING OUTDATED ROUTERS. CHECK YOURS NOW

How this router attack worked
This attack focused on SOHO routers. That stands for small office and home office routers. In other words, these are the kinds of devices used by small businesses, remote workers and some homes. The Justice Department says the hackers used weaknesses in older routers to change DNS settings.
DNS is like the address book for the internet. When you type a website name, DNS helps your device find the right online destination. If hackers control that address book, they can send certain requests through their own servers. That can let them spot valuable targets and try to steal passwords, authentication tokens, emails or browsing data.
That to me is scary because the victim may not see anything obvious. Your laptop may still connect. Your phone may still browse. Your router may still look normal. Meanwhile, the traffic can be quietly routed through a bad path.
Why old routers can become a weak spot
Routers age like any other device. The problem is that many people keep them for years after the manufacturer stops supporting them. That can leave known security holes sitting open.
Many people also never change the router’s admin username and password. That admin login is different from your Wi-Fi password. It controls the router itself. If that login still uses a default password, a hacker has a much easier path inside.
Think of it this way. You may have strong passwords on your bank account, email and phone. But if your router is outdated and poorly protected, your network still has a soft spot.
DON’T USE YOUR HOME WI-FI BEFORE FIXING CERTAIN SECURITY RISKS

Which routers were targeted?
The FBI specifically referred to the TP-Link WR841N in its warning. The UK National Cyber Security Centre also listed other TP-Link models targeted by APT28. The agency says the list may not be complete.
Here are the routers named in the advisory:
- TP-Link LTE Wireless N Router MR6400
- TP-Link Wireless Dual Band Gigabit Router Archer C5
- TP-Link Wireless Dual Band Gigabit Router Archer C7
- TP-Link Wireless Dual Band Gigabit Router WDR3600
- TP-Link Wireless Dual Band Gigabit Router WDR4300
- TP-Link Wireless Dual Band Router WDR3500
- TP-Link Wireless Lite N Router WR740N
- TP-Link Wireless Lite N Router WR740N/WR741ND
- TP-Link Wireless Lite N Router WR749N
- TP-Link Wireless N 3G/4G Router MR3420
- TP-Link Wireless N Access Point WA801ND
- TP-Link Wireless N Access Point WA901ND
- TP-Link Wireless N Gigabit Router WR1043ND
- TP-Link Wireless N Gigabit Router WR1045ND
- TP-Link Wireless N Router WR840N
- TP-Link Wireless N Router WR841HP
- TP-Link Wireless N Router WR841N
- TP-Link Wireless N Router WR841N/WR841ND
- TP-Link Wireless N Router WR842N
- TP-Link Wireless N Router WR842ND
- TP-Link Wireless N Router WR845N
- TP-Link Wireless N Router WR941ND
- TP-Link Wireless N Router WR945N
If you see your model on this list, take it seriously. Many of these routers are older. Some may no longer get normal security support. We reached out to TP-Link for comments, but did not hear back before our deadline.
What TP-Link says about the router warnings
A spokesperson from TP-Link Systems Inc. told CyberGuy the company is aware of recent public reporting involving legacy consumer routers, including TP-Link models listed in those reports. The company said the referenced legacy router models reached End of Service and Life status several years ago.
“While these products are outside our standard maintenance lifecycle, TP-Link has developed security updates for select legacy models where technically feasible,” the spokesperson said.
The spokesperson also urged customers using legacy or end-of-service devices to upgrade to currently supported hardware that receives regular security updates.
“As immediate precautions, users should update to the latest available firmware, disable remote management, and restrict device access to trusted internal networks only,” the spokesperson said.
TP-Link added that the security of its customers is its highest priority and said detailed mitigation guidance, along with a list of identified affected legacy products, is available on its official security advisory page.
What this means for you
Most people do not think about their router until the Wi-Fi drops. But your router sits between your devices and the internet. That gives it a powerful position in your home or small business. If a hacker changes the router’s settings, every connected device can feel the impact. That includes your laptop, smartphone, tablet, smart TV and work computer.
This is especially important if you work from home. A weak router can create a risk for your personal accounts and your workplace accounts. The good news is that you do not need to be a cybersecurity expert to lower the risk. You just need to stop treating your router like a forgotten appliance.

How to protect your router from hackers
The good news is that a few simple router checks can reduce your risk and help keep hackers from quietly changing how your internet traffic moves.
1) Check your router model
Look at the label on your router. You can usually find the model number on the bottom or back of the device. If it matches one of the listed models, check the manufacturer’s support page for firmware updates. If the device is no longer supported, replace it. Do not keep an end-of-life router because it “still works.” A router can still provide Wi-Fi while leaving your network exposed.
2) Update your router firmware
Firmware is the software that runs your router. Updates often fix security problems. Open your router’s app or log in to its admin page. Look for a firmware update section. Turn on automatic updates if your router offers that option. If it does not, set a reminder to check for updates regularly.
3) Change the router admin password
Your router has an admin login. This is separate from your Wi-Fi network password. Change the default admin username and password. Use a long, unique password that you do not use anywhere else. A password manager can help you create and store a strong router password so you do not have to remember it. Also, change your Wi-Fi password if you have shared it widely or kept it for years. Check out the best expert-reviewed password managers of 2026 at Cyberguy.com
4) Disable remote management
Most people do not need to manage a home router from outside the house. Remote management can give attackers another way to reach your router. Log in to your router settings and turn it off unless you truly need it. The wording may vary by brand. Look for “remote management,” “remote access” or “WAN access.”
5) Reboot your router
A reboot will not fix every router problem. However, security agencies often recommend restarting routers as part of basic home network hygiene. Unplug your router, wait about 30 seconds and plug it back in. This can help clear some temporary malicious activity. Still, it does not replace updates, stronger passwords or replacing an outdated device.
6) Watch browser certificate warnings
Do not click through browser warnings that say a site certificate is invalid or unsafe. Those warnings can appear when something is interfering with a secure connection. In this kind of attack, that warning could be a major red flag. Close the page instead. Then check the site by typing the address yourself on a trusted network.
7) Use a VPN for sensitive work
If you handle work files or sensitive accounts from home, use your company-approved VPN. A VPN can help protect traffic when you connect to workplace systems. It can also reduce exposure when you use networks you do not fully control. Still, a VPN isn’t a free pass to ignore router updates. You need safer habits and safer hardware. For the best VPN software, see my expert review of the best VPNs for browsing the web privately on your Windows, Mac, Android & iOS devices at Cyberguy.com
8) Use strong antivirus software
Strong antivirus software can help protect your devices if a bad link, a fake login page or a malicious download reaches you. It will not fix a vulnerable router, but it can add another layer of protection for your computer and phone. Look for security software that can detect malware, warn you about phishing sites and help block suspicious activity before it causes damage. Get my picks for the best 2026 antivirus protection winners for your Windows, Mac, Android & iOS devices at Cyberguy.com
9) Consider identity theft protection
If hackers steal your login details, the damage can spread beyond your Wi-Fi network. Identity theft protection can help monitor for signs that your personal information is being misused. It may alert you to suspicious activity involving your credit, accounts or personal data so you can act faster. See my tips and best picks on Best Identity Theft Protection at Cyberguy.com
10) Use a data removal service
A data removal service can help reduce the amount of personal information about you that is available online. That is important because scammers often combine stolen logins with exposed details from data broker sites. Removing your information from those sites can make it harder for criminals to build a fuller profile of you or your family. Check out my top picks for data removal services and get a free scan to find out if your personal information is already out on the web by visiting Cyberguy.com
11) Replace outdated routers
If your router no longer receives security updates, replace it. That may feel annoying. I get it. Nobody gets excited about buying a router the way they might get excited about a new phone. But your router protects everything connected to it. Spending money on a supported device can be cheaper than cleaning up stolen passwords later.
Kurt’s key takeaways
This router warning should make every home and small business owner pause for a minute. The scariest part is how ordinary the target is. We are talking about routers that may be sitting in homes, home offices and small businesses right now. The FBI and its partners disrupted part of the Russian operation. However, that does not magically secure old routers still sitting on shelves. So check your model. Update the firmware. Change the admin password. Turn off remote management. Replace the router if it no longer gets updates. Your router may be boring. But if it gets hijacked, it can become one of the most important security problems in your home.
Would you know how old your router is right now, or is it one of those devices you have not touched since the day it was installed? Let us know by writing to us at Cyberguy.com
