Ethernet vs Wi-Fi security comparison reveals surprising results for home users seeking protection
NEWYou can now listen to Fox News articles!
We spend so much time online that how we connect to the internet has become almost as important as the devices we use. Most people never give it a second thought. They connect their computer to Wi-Fi, type in a password and get on with their day. But if you have ever wondered whether plugging in an Ethernet cable is safer than sticking to wireless, you are asking the right question. The way you connect can have real consequences for your privacy and security. Recently, Kathleen reached out to me with the same doubt.
“Is it more secure to use the Ethernet connection at home for my computer, or is it safer to use the Wi-Fi from my cable provider?”
It’s a great question, Kathleen, because both options seem similar on the surface but work very differently under the hood. Those differences can mean the difference between a private, secure connection and one that’s more vulnerable to attackers.

Ethernet offers direct, wired security without wireless risks. (Kurt “CyberGuy” Knutsson)
How Ethernet and Wi-Fi differ when it comes to security
Ethernet and Wi-Fi both get you online, but they do it in completely different ways. Ethernet uses a physical cable that connects your computer directly to the router. Since it is a wired connection, data travels straight through that cable, making it much harder for anyone to intercept it. There is no wireless signal to hijack, no airwaves to eavesdrop on.
Wi-Fi, on the other hand, is built on convenience. It sends your data through the air to and from your router, which is what makes it so easy to connect from anywhere in your home. But that convenience comes with more risk. Anyone within range of your signal could potentially try to break into the network. If your Wi-Fi is protected by a weak password or uses outdated encryption, a skilled attacker might gain access without ever stepping inside your house.
At home, that risk is smaller than in a coffee shop or hotel, but it is not zero. Even a poorly secured smart device on your network can give attackers a way in. Ethernet removes many of those risks simply because it is harder to access a connection that requires physical access to a cable. Check out our steps for setting up a home network like a pro here.
DON’T USE YOUR HOME WI-FI BEFORE FIXING CERTAIN SECURITY RISKS
Why one connection might be safer than the other
It is easy to think Ethernet is automatically safer, but that is not the whole story. Your real security depends on how your entire network is set up. For example, a Wi-Fi network with a strong password, up-to-date router firmware, and WPA3 encryption is going to be far more secure than a poorly configured Ethernet setup connected to an outdated router.
There is also the question of who else uses your network. If it is just you and a handful of devices, your risk is low. But if you live in a shared space or run smart home gadgets, that changes the equation. Each device connected to Wi-Fi is a potential entry point. Ethernet reduces the number of devices that can connect, which limits the attack surface.
Ultimately, the connection type is one piece of the puzzle. The bigger factors are how your router is configured, how often you update your software, and how careful you are with what devices you connect.
Wi-Fi brings convenience but also potential exposure to hackers. (Kurt “CyberGuy” Knutsson)
6 ways to make your internet safer
Whether you stick with Wi-Fi or switch to Ethernet, there are several practical steps you can take to protect your devices and data. Each step adds an extra layer of security to your network.
IS YOUR HOME WI-FI REALLY SAFE? THINK AGAIN
1) Use a strong network password
Choose a long and unique password for your Wi-Fi. Avoid obvious choices like your name, address, or simple sequences. A strong password makes it far harder for attackers to guess or crack your network. A password manager helps you create and store strong, unique passwords for every account, reducing the chances of a hacker gaining access through weak or repeated credentials.
Next, see if your email has been exposed in past breaches. Our #1 password manager (see Cyberguy.com/Passwords) pick includes a built-in breach scanner that checks whether your email address or passwords have appeared in known leaks. If you discover a match, immediately change any reused passwords and secure those accounts with new, unique credentials.

2) Enable the latest encryption on your router
Most modern routers support WPA3, which is much more secure than older standards like WPA2. Check your router’s settings to enable the latest encryption and ensure your network traffic is harder to intercept.
3) Keep your router firmware updated
Router manufacturers regularly release updates that patch security vulnerabilities. Log into your router’s admin panel occasionally to check for updates and install them as soon as they are available. This prevents attackers from exploiting known flaws.

4) Review connected devices
Regularly check which devices are connected to your network and disconnect anything you no longer use. Each connected device is a potential entry point for attackers, so keeping the list limited reduces your network’s exposure.
5) Install strong antivirus software
Even on a secure network, malware can sneak in through downloads, phishing attacks, or compromised websites. A strong antivirus program will detect and block malicious activity, protecting your computer before damage occurs.
The best way to safeguard yourself from malicious links that install malware, potentially accessing your private information, is to have strong antivirus software installed on all your devices. This protection can also alert you to phishing emails and ransomware scams, keeping your personal information and digital assets safe.

6) Use a VPN for sensitive tasks
A virtual private network encrypts your internet traffic, making it unreadable to outsiders. This is especially useful if you ever use Wi-Fi in public or need an extra layer of privacy at home. A reliable VPN is essential for protecting your online privacy and ensuring a secure, high-speed connection.

Kurt’s key takeaway
So, which is safer, Ethernet or Wi-Fi? Ethernet wins in raw security because it eliminates many of the risks that come with wireless connections. But in a well-secured home network, the difference is often smaller than most people think. What matters more is how you manage your devices, passwords, software, and online habits.

Siri Shortcuts now works with Samsung SmartThings routines
Samsung’s latest SmartThings update adds support for Siri Shortcuts. In a press release, Samsung announced that you can now use Siri to run SmartThings routines, allowing you to use Apple’s voice assistant to control your smart home.
Siri Shortcuts is a feature in iOS that lets you run automations by asking Siri. These can either be created by the user in the Shortcuts app or by the manufacturers in their app.
This update should make it easier to control your SmartThings home using your iPhone, HomePod, or other Apple device. For example, you can now call on Siri to trigger your “Good morning” routine through SmartThings that automatically adjusts the lights, turns on your coffee maker, and opens your blinds when you wake up.
Samsung is also enhancing its SmartThings app for Apple devices. On the Apple Watch, you can now see a full list of your devices, send commands, and carry out routines, while the SmartThings app for iOS gives you the ability to view and control up to five of your most recently used devices from your lock screen with Live Activities.

The #1 Google search scam everyone falls for
NEWYou can now listen to Fox News articles!
When something goes wrong with your bank account or delivery, your first instinct might be to type the company name into Google and call the first customer service number you see. But that simple search has become one of the biggest traps for scammers, and it’s costing people money, privacy and even control over their phones.

A simple Google search for a company’s customer service number can lead straight to a scam. The first result isn’t always the safest one. (Kurt “CyberGuy” Knutsson)
He Googled his bank’s number and lost control of his phone
Here’s how one man’s quick search for help turned into a nightmare he never expected. Gabriel wrote to us in distress, asking,
“I called my bank to check on some charges I didn’t authorize. I called the number on the bank statement, but they told me to go online. I googled the company and dialed the first number that popped up. Some foreign guy got on the phone, and I explained about the charges. Somehow, he took control of my phone, where I didn’t have any control. I tried to shut it down and hang up, but I couldn’t. He ended up sending an explicit text message to my 16-year-old daughter. How do I prove I didn’t send that message? Please help.”
Gabriel’s story is frightening, and unfortunately, it’s not rare. This type of attack is called a remote access support scam. Scammers pretend to be bank or tech support, then trick you into installing a program that gives them control of your device. Once inside, they can steal passwords, send messages or lock you out completely.
WHATSAPP BANS 6.8M SCAM ACCOUNTS, LAUNCHES SAFETY TOOL
Gabriel thought he was calling his bank, but the number was fake. Within minutes, a scammer took control of his phone and invaded his privacy. (Kurt “CyberGuy” Knutsson)
Why this scam works
Search engines reward paid ads. Scammers take advantage of this by buying ad space to appear above legitimate customer service numbers. The fake pages look professional, complete with company logos and 800 numbers that seem real.
Once you call, the fake “agent” sounds knowledgeable and polite. They build trust, then convince you to install remote access software such as AnyDesk or TeamViewer. From that point, they can control everything on your phone.
What to do if this happens to you
Gabriel, what you went through is incredibly upsetting, and you’re right to take it seriously. Here’s what to do right away:
1) Disconnect and secure your phone
Turn off your phone immediately. Restart it in Airplane Mode and don’t connect to Wi-Fi yet. Run a full antivirus scan with strong antivirus software.
2) Change all your passwords
Use a secure device that has not been compromised to reset the passwords for your key accounts, including email, cloud storage, phone carrier and banking logins. Create strong, unique passwords for each account and enable two-factor authentication (2FA) for added protection on all your devices and platforms.
Next, see if your email has been exposed in past breaches. Our #1 password manager (see Cyberguy.com) pick includes a built-in breach scanner that checks whether your email address or passwords have appeared in known leaks. If you discover a match, immediately change any reused passwords and secure those accounts with new, unique credentials.

3) Contact your carrier and your bank
Let your phone provider know that your device was taken over. Ask them to check for unauthorized remote management apps or SIM-swap activity. Notify your bank’s fraud department and report the fake number you found on Google.
4) Report the explicit message
Take screenshots and save everything. Contact local police and explain that the message was sent from your number while your phone was under remote control. If a minor is involved, the case may be referred to the FBI’s Internet Crime Complaint Center (IC3.gov).
5) Factory reset your phone
Once your data is backed up, perform a factory reset on your iPhone or Android to remove any hidden software. Reinstall only apps you recognize from the official app store.

Tips to stay safe from fake customer service scams
Falling for a fake customer service number can happen to anyone, especially when you’re in a rush or worried about your account. Here’s how to make sure you never get tricked by the same kind of scam that hijacked Gabriel’s phone.
Go directly to the company’s official website
Always type the company’s web address yourself or use the contact number printed on your card or statement. Scammers often create fake numbers that appear in search results, hoping you’ll call them instead of your real bank.
Don’t trust the first search result on Google
Search engines sell ad space to anyone, including criminals posing as real businesses. Those top “sponsored” listings can lead straight to scammers. Instead, scroll down until you find the official domain ending in .com, .org or .gov.
Never allow remote access to your phone or computer
No legitimate company needs to control your device to verify charges or fix an account issue. If someone asks you to install software like AnyDesk or TeamViewer, hang up immediately. These tools give strangers complete control of your screen and data.
Hang up if the caller pressures you to act fast
Scammers rely on panic. When someone insists you act “right now” or risk losing money, that’s a warning sign. Stay calm, hang up, and verify the problem through your bank’s official website or number.
Use strong antivirus protection
Install and regularly update a trusted antivirus app. Strong antivirus software can block remote-access tools and spyware before scammers gain access. Regular scans also detect hidden threats that may already be on your phone or computer.
The best way to safeguard yourself from malicious links that install malware, potentially accessing your private information, is to have strong antivirus software installed on all your devices. This protection can also alert you to phishing emails and ransomware scams, keeping your personal information and digital assets safe.

Consider using a data removal service
Many scammers find victims through data brokers that sell phone numbers and personal details. A data removal service helps erase your information from these sites. As a result, it’s harder for criminals to target you with fake customer service scams in the first place.
While no service can guarantee the complete removal of your data from the internet, a data removal service is really a smart choice. They aren’t cheap, and neither is your privacy. These services do all the work for you by actively monitoring and systematically erasing your personal information from hundreds of websites. It’s what gives me peace of mind and has proven to be the most effective way to erase your personal data from the internet. By limiting the information available, you reduce the risk of scammers cross-referencing data from breaches with information they might find on the dark web, making it harder for them to target you.

Monitor your identity with a trusted protection service
Even a short breach can expose your private information. Identity-monitoring tools alert you when your name, email or Social Security number appears on the dark web. That gives you time to act before scammers can use it.
Identity Theft companies can monitor personal information like your Social Security Number (SSN), phone number, and email address, and alert you if it is being sold on the dark web or being used to open an account. They can also assist you in freezing your bank and credit card accounts to prevent further unauthorized use by criminals.

Kurt’s key takeaways
The internet has made getting help easier than ever, but it has also made it easier for scammers to pretend to be helpful. The top way people are being scammed today isn’t through phishing emails or suspicious links; it’s by trusting fake phone numbers that look official. Take a few minutes to save the real customer service numbers for your bank, phone provider, and credit card company. One quick call to the wrong number could give a stranger access to your entire digital life.
With fake customer service numbers flooding search results, should Google be held responsible for protecting you from these scams? Let us know by writing to us at Cyberguy.com

Blue Origin scrubs second New Glenn launch
The second launch of Blue Origin’s partially reusable New Glenn rocket was scrubbed on Sunday due to adverse weather conditions, delaying NASA’s latest Mars mission. The Jeff Bezos-owned commercial space company announced that its next launch window from Cape Canaveral Space Force Station in Florida will be attempted “no earlier” than Wednesday, November 12th, between 2:50PM and 4:17PM ET.
This is a significant launch for the 320-foot-tall megarocket, which is tasked with sending NASA’s twin ESCAPADE (Escape and Plasma Acceleration and Dynamics Explorers) probes into space — the first Mars-bound mission since NASA launched its Perseverance and Ingenuity vehicles in 2020 to explore the red planet’s surface. The ESCAPADE satellites are projected to reach Mars orbit in 2027, where they will measure the planet’s magnetic field and atmosphere.
This will also be Blue Origin’s latest attempt to land New Glenn’s reusable first-stage booster, which, much like SpaceX’s Falcon rocket boosters, is designed to vertically touch down on a sea-based platform following launch. While Blue Origin successfully launched New Glenn for the first time in January after several delays, the booster was lost during its landing descent. A successful launch and landing would help Blue Origin to prove itself as a deep-space launch provider that’s capable of competing with established rivals like SpaceX and United Launch Alliance.
Blue Origin says it worked with the Federal Aviation Administration to select its latest launch window, having seemingly been given an exemption to new FAA rules that prohibit commercial rockets from being launched between 6AM and 10PM. This emergency order came into effect on November 10th to alleviate air traffic congestion during the ongoing government shutdown. If all goes to plan, the live webcast for New Glenn’s second flight will start 20 minutes prior to launch on Wednesday.
