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.

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 If your Wi-Fi is protected by a weak password or uses outdated encryption, a skilled attacker might gain access without ever stepping inside your house.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.

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.

The Polaroid Flip, my favorite retro instant camera, is cheaper than ever
I love instant cameras because of how they help me slow down and be creative without the distractions of a phone. Holding a real print also feels grounding in a screen-dominated age, which is why I think a lot of people these days are drawn to them — and why models with old-school vibes like the Polaroid Flip make such great gifts. It’s usually pricey, but today you can buy the Flip for $184.99 ($35 off) directly from Polaroid, which is its best price to date. Amazon is also selling the camera with two packs of film for $212.49 ($37 off), which marks a new low too.
Polaroid cameras offer the most charming, old-fashioned instant-film experience of any I’ve tested, and the Flip is no exception. It sports a classic, retro-inspired design with a flip-up lid and prints vintage-style square I-Type photos with Polaroid’s iconic white frame. Yet at the same time it’s got the perfect amount of subtle modern conveniences baked in, like Bluetooth, USB-C charging, and a beginner-friendly companion app that lets you adjust saturation and exposure.
But what makes it really stand out is its picture quality, which outshines other Polaroid models in this price range. The Flip has the most powerful flash of any Polaroid camera, and paired with its unique sonar autofocus and four-lens hyperfocal system, it produces sharper, more consistently in-focus images than any model Polaroid offers at this price. You can manually tweak exposure, too, and the camera even sends warnings you when a shot is likely to be over- or underexposed. These are all features that go a long way toward reducing the number of wasted shots, which is helpful given I-Type film costs a whopping $18.99 for just eight prints.
That said, the instant camera’s not for everyone. Fujifilm’s cheaper Instax Mini 12 develops prints much faster and looks more true-to-life while struggling less in low light. Still, the Flip’s dreamy, vintage aesthetic has its own appeal, especially if you prefer a more artistic, old-fashioned look.

New email scam uses hidden characters to slip past filters
NEWYou can now listen to Fox News articles!
Cybercriminals keep finding new angles to get your attention, and email remains one of their favorite tools. Over the years, you have probably seen everything from fake courier notices to AI-generated scams that feel surprisingly polished. Filters have improved, but attackers have learned to adapt. The latest technique takes aim at something you rarely think about: the subject line itself. Researchers have found a method that hides tiny, invisible characters inside the subject so automated systems fail to flag the message. It sounds subtle, but it is quickly becoming a serious problem.

NEW SCAM SENDS FAKE MICROSOFT 365 LOGIN PAGES

How the new trick works
Researchers recently uncovered phishing campaigns that embed soft hyphens between every letter of an email subject. These are invisible Unicode characters that normally help with text formatting. They do not show up in your inbox, but they completely throw off keyword-based filters. Attackers use MIME encoded-word formatting to slip these characters into the subject. By encoding it in UTF-8 and Base64, they can weave these hidden characters through the entire phrase.
One analyzed email decoded to “Your Password is About to Expire” with a soft hyphen tucked between every character. To you, it looks normal. To a security filter, it looks scrambled, with no clear keyword to match. The attackers then use the same trick in the body of the email, so both layers slide through detection. The link leads to a fake login page sitting on a compromised domain, designed to harvest your credentials.
If you have ever tried spotting a phishing email, this one still follows the usual script. It builds urgency, claims something is about to expire and points you to a login page. The difference is in how neatly it dodges the filters you trust.
Why this phishing technique is super dangerous
Most phishing filters rely on pattern recognition. They look for suspicious words, common phrases and structure. They also scan for known malicious domains. By splitting every character with invisible symbols, attackers break up these patterns. The text becomes readable for you but unreadable for automated systems. This creates a quiet loophole where old phishing templates suddenly become effective again.
The worrying part is how easy this method is to copy. The tools needed to encode these messages are widely available. Attackers can automate the process and churn out bulk campaigns with little extra effort. Since the characters are invisible in most email clients, even tech-savvy users do not notice anything odd at first glance.
Security researchers point out that this method has appeared in email bodies for years, but using it in the subject line is less common. That makes it harder for existing filters to catch. Subject lines also play a key role in shaping your first impression. If the subject looks familiar and urgent, you are more likely to open the email, which gives the attacker a head start.
How to spot a phishing email before you click
Phishing emails often look legitimate, but the links inside them tell a different story. Scammers hide dangerous URLs behind familiar-looking text, hoping you will click without checking. One safe way to preview a link is by using a private email service that shows the real destination before your browser loads it.
Our top-rated private email provider recommendation includes malicious link protection that reveals full URLs before opening them. This gives you a clear view of where a link leads before anything can harm your device. It also offers strong privacy features like no ads, no tracking, encrypted messages and unlimited disposable aliases.

9 steps you can take to protect yourself from this phishing scam
You do not need to become a security expert to stay safe. A few habits, paired with the right tools, can shut down most phishing attempts before they have a chance to work.
1) Use a password manager
A password manager helps you create strong, unique passwords for every account. Even if a phishing email fools you, the attacker cannot use your password elsewhere because each one is different. Most password managers also warn you when a site looks suspicious.
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.
Check out the best expert-reviewed password managers of 2025 at Cyberguy.com.
2) Enable two-factor authentication
Turning on 2FA adds a second step to your login process. Even if someone steals your password, they still need the verification code on your phone. This stops most phishing attempts from going any further.
3) Install a reliable antivirus software
Strong antivirus software does more than scan for malware. Many can flag unsafe pages, block suspicious redirects and warn you before you enter your details on a fake login page. It is a simple layer of protection that helps a lot when an email slips past filters.
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.

4) Limit your personal data online
Attackers often tailor phishing messages using information they find about you. Reducing your digital footprint makes it harder for them to craft emails that feel convincing. You can use personal data removal services to clean up exposed details and old database leaks.
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.

5) Check sender details carefully
Do not rely on the display name. Always check the full email address. Attackers often tweak domain names by a single letter or symbol. If something feels off, open the site manually instead of clicking any link inside the email.
6) Never reset passwords through email links
If you get an email claiming your password will expire, do not click the link. Go to the website directly and check your account settings. Phishing emails rely on urgency. Slowing down and confirming the issue yourself removes that pressure.
7) Keep your software and browser updated
Updates often include security fixes that help block malicious scripts and unsafe redirects. Attackers take advantage of older systems because they are easier to trick. Staying updated keeps you ahead of known weaknesses.
8) Turn on advanced spam filtering or “strict” filtering
Many email providers (Gmail, Outlook, Yahoo) allow you to tighten spam filtering settings. This won’t catch every soft-hyphen scam, but it improves your odds and reduces risky emails overall.
9) Use a browser with anti-phishing protection
Chrome, Safari, Firefox, Brave, and Edge all include anti-phishing checks. This adds another safety net if you accidentally click a bad link.

Kurt’s key takeaway
Phishing attacks are changing fast, and tricks like invisible characters show how creative attackers are getting. It’s safe to say filters and scanners are also improving, but they cannot catch everything, especially when the text they see is not the same as what you see. Staying safe comes down to a mix of good habits, the right tools, and a little skepticism whenever an email pushes you to act quickly. If you slow down, double-check the details, and follow the steps that strengthen your accounts, you make it much harder for anyone to fool you.

DRAM it! Raspberry Pi raises prices
Raspberry Pi is increasing the price of several single-board computers in an attempt to offset soaring memory costs. The updates are being applied immediately and affect Raspberry Pi 4 and Raspberry Pi 5, with prices increasing by $5 to $25 depending on the model and amount of RAM. The 16GB memory variants of the Compute Module 5 are also being raised by $20, now starting at $140.
“The current pressure on memory prices, driven by competition from the AI infrastructure roll-out, is painful but ultimately temporary,” Raspberry Pi CEO Eben Upton said in the announcement. “We remain committed to driving down the cost of computing and look forward to unwinding these price increases once it abates.”
An affordable new 1GB variant of Raspberry Pi’s flagship 5 model is also being introduced for $45, which includes a quad-core 2.4GHz Arm Cortex-A76 processor, dual-band Wi-Fi, and a PCI Express port.
Raspberry Pi isn’t the only computing hardware provider feeling the pinch, with CyberPowerPC and Maingear having also addressed how the skyrocketing price of RAM is impacting their business, with price increases either already in place or expected in the future. The limited supply and high demand for RAM has led to some stores selling it at market prices, just as the out-of-control GPU prices from earlier this year had finally started to settle down.
