The biggest Wi-Fi mistake you didn’t know you were making

You’ve got dinner in the oven, you’re looking for extra glasses, and your cousin’s kid screams (again), “What’s the Wi-Fi password?” You’re juggling a hundred things at once, and the last thing you want to do is to spell out your password.

Here’s the good news: You can slap a printout on the fridge, and everyone can scan it with their phones to connect. But first, I’ll show you how to create a separate network so you don’t need to worry about little Billy getting into your personal stuff on your devices and computers.

SCAMMERS ARE TARGETING TEENS WITH THESE NASTY TRICKS

When guests connect to your main Wi-Fi, they can potentially access devices like smart TVs, printers, and even your laptop or phone if file sharing is enabled. Worse, if their device is compromised, your whole network could be at risk. A guest network keeps everyone happy while keeping your private life private.

Most modern routers let you set up a guest network without having to be a tech guru. Warning: This will take you a few minutes, but it’s totally doable.

RELATED: Is your internet slo-o-o-w? Let’s fix that.

Step 1: Log into your router’s admin console. You’ll need your IP address. You can usually find this on a sticker on the bottom or side of your router. Seeing 192.168.1.1 or 192.168.0.1 is common.

If you don’t see yours …

  • On Windows: Open the Start menu, search for “Command Prompt” and, with your Command Prompt open, type in ipconfig and press Enter. Look for the line that says “Default Gateway.” This is your router’s IP address.
  • On Mac: Go to System Settings > Network. Select your Wi-Fi network > Advanced. Your router’s IP address is under Router.

Step 2: Open your browser, type http:// and paste in your IP address. Hit Enter to open a login page. For the credentials, try the username admin and the word password for the password. If the defaults are different, they’re likely printed on your router. You can also check this site that lists default passwords for almost every router in use.

Step 3: Look for a setting called Guest Network or Guest Wi-Fi. Give it a different name (aka SSID) than your main network, along with a strong, unique password.

TECH TIP: SAVE YOUR MEMORIES BEFORE IT’S TOO LATE

If you have snoops in the family … When family and friends connect to your Wi-Fi guest network, you can block them from accessing your files or devices on your primary network. Turn off the local access setting.

Sorry, but dedicated snoops won’t stop at one closed door. Here’s a sign someone is poking around.

While you’re at it, a quick security check

Before you finish, take these extra steps to lock things down:

BIOMETRIC DATA: IS IT SAFE TO HAND IT OVER TO ANY COMPANY THAT ASKS?

  • Change your admin password: If your router still uses the default login, update it.
  • Update your firmware, too: Check for software updates to keep your router secure from vulnerabilities.

Your network is a bigger target than you realize.

Now for the fun part

Create a QR code that automatically connects guests to your new guest network — no hassle, no drama. With the free site QIFI.org, all you need is three pieces of info:

  1. SSID: This is your Wi-Fi network name. Find it on the back of your modem, in the admin console or on your network app.
  2. Encryption type: Choose WPA/WPA2/WPA3. You can find this in your phone’s Wi-Fi section under the network details.
  3. Key: This is your router password. It’s on the back of your router if you’ve never changed it. (Please tell me you’ve changed it!)

Hit Generate and your QR code is ready. Print some copies of it to hang around the house, or do what I did: Order this custom sign that looks classy. Now, when someone asks for the Wi-Fi password, you can just point.

A Kinect for kids is outselling Xbox to become the hot toy this holiday

Two years ago, the company sold about 5,000 units of the Playground. Last year, that number was roughly 150,000. This year, it’s on track for 600,000. Before its pivot, Nex did about $3 million of annual revenue and wasn’t profitable. This year, the company is projecting more than $150 million of sales and says it’s on pace to finally break even.

Fake Windows update pushes malware in new ClickFix attack

Fake Windows update pushes malware in new ClickFix attack

NEWYou can now listen to Fox News articles!

Cybercriminals keep getting better at blending into the software you use every day. 

Over the past few years, we’ve seen phishing pages that copy banking portals, fake browser alerts that claim your device is infected and “human verification” screens that push you to run commands you should never touch. The latest twist comes from the ongoing ClickFix campaign.

Instead of asking you to prove you are human, attackers now disguise themselves as a Windows update. It looks convincing enough that you might follow the instructions without thinking, which is exactly what they want.

NEW SCAM SENDS FAKE MICROSOFT 365 LOGIN PAGES

How the fake update works

Researchers noticed that ClickFix has upgraded its old trick. The campaign used to rely on human verification pages, but now you get a full-screen Windows update screen that looks almost identical to the real thing. Joe Security showed how the page displays fake progress bars, familiar update messages and a prompt that tells you to complete a critical security update.

If you are on Windows, the site tells you to open the Run box, copy something from your clipboard and paste it in. That “something” is a command that silently downloads a malware dropper. The final payload is usually an infostealer, which steals passwords, cookies and other data from your machine.

NEW EMAIL SCAM USES HIDDEN CHARACTERS TO SLIP PAST FILTERS

The moment you paste the command, the infection chain begins. First, a file called mshta.exe reaches out to a remote server and grabs a script. To avoid detection, these URLs often use hex encoding for parts of the address and rotate their paths. The script then runs obfuscated PowerShell code filled with junk instructions to throw researchers off. Once PowerShell does its work, it decrypts a hidden .NET assembly that functions as the loader.

Why is this attack so hard to detect?

The loader hides its next stage inside what looks like a regular PNG file. ClickFix uses custom steganography, which is a technique that hides secret data inside normal-looking content. In this case, the malware sits inside the image’s pixel data. The attackers tweak color values in certain pixels, especially in the red channel, to embed pieces of shellcode. When you view the image, everything appears normal.

The script knows exactly where the hidden data sits. It extracts the pixel values, decrypts them and rebuilds the malware directly in memory. That means nothing obvious is written to disk. Security tools that rely on file scanning miss it, since the shellcode never appears as a standalone file.

Once rebuilt, the shellcode is injected into a trusted Windows process like explorer.exe. The attack uses familiar in-memory techniques such as VirtualAllocEx, WriteProcessMemory and CreateRemoteThread. Recent ClickFix activity has delivered infostealers like LummaC2 and updated versions of Rhadamanthys. These tools are built to harvest credentials and send them back to the attacker with very little noise.

7 steps you can take to protect yourself from the ClickFix campaign

The best way to stay protected is to slow down for a moment and follow a few steps that cut off these attacks before they start.

1) Never run commands you didn’t ask for

If any site tells you to paste a command into Run, PowerShell or Terminal, treat it as an immediate warning sign. Real operating system updates never require you to run commands from a webpage. When you run that command, you hand full control to the attacker. If something feels off, close the page and don’t interact further.

2) Keep Windows updates inside Windows

Updates should only come from the Windows Settings app or through official system notifications. A browser tab or pop-up pretending to be a Windows update is always fake. If you see anything outside the normal update flow asking for your action, ignore it and check the real Windows Update page yourself.

3) Use a reputable antivirus

Choose a security suite that can detect both file-based and in-memory threats. Stealthy attacks like ClickFix avoid leaving obvious files for scanners to pick up. Tools with behavioral detection, sandboxing and script monitoring give you a much better chance of spotting unusual activity early.

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) Use a password manager

Password managers create strong, unique passwords for every account you use. They also autofill only on legitimate websites, which helps you catch fake login pages. If a manager refuses to fill out your credentials, take a second look at the URL before entering anything manually.

Next, see if your email has been exposed in past breaches. Our No. 1 password manager 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.

5) Use a personal data removal service

Many attacks start by targeting emails and personal details already exposed online. Data removal services help shrink your digital footprint by requesting takedowns from data broker sites that collect and sell your information. They can’t erase everything, but reducing your exposure means fewer attackers have easy access to your details.

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.

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.

6) Check URLs before trusting anything

A convincing layout doesn’t mean it is legitimate. Always look at the domain name first. If it doesn’t match the official site or uses odd spelling or extra characters, close it. Attackers rely on the fact that people recognize a page’s design but ignore the address bar.

7) Close suspicious full-screen pages

Fake update pages often run in full-screen mode to hide the browser interface and make the page look like part of your computer. If a site suddenly goes full screen without your permission, exit with Esc or Alt+Tab. Once you’re out, scan your system and don’t return to that page.

Kurt’s key takeaway

ClickFix works because it leans on user interaction. Nothing happens unless you follow the instructions on the screen. That makes the fake Windows update page especially dangerous, because it taps into something most people trust. If you are used to Windows updates freezing your screen, you may not question a prompt that appears during the process. Cybercriminals know this. They copy trusted interfaces to lower your guard and then rely on you to run the final command. The technical tricks that follow are complex, but the starting point is simple. They need you to help them.

Parents call for New York governor to sign landmark AI safety bill

Parents call for New York governor to sign landmark AI safety bill

A group of more than 150 parents sent a letter on Friday to New York governor Kathy Hochul, urging her to sign the Responsible AI Safety and Education (RAISE) Act without changes. The RAISE Act is a buzzy bill that would require developers of large AI models — like Meta, OpenAI, Deepseek, and Google — to create safety plans and follow transparency rules about reporting safety incidents.

The bill passed in both the New York State Senate and the Assembly in June. But this week, Hochul reportedly proposed a near-total rewrite of the RAISE Act that would make it more favorable to tech companies, akin to some of the changes made to California’s SB 53 after large AI companies weighed in on it.

Many AI companies, unsurprisingly, are squarely against the legislation. The AI Alliance, which counts
Meta, IBM, Intel, Oracle, Snowflake, Uber, AMD, Databricks, and Hugging Face among its members, sent a letter in June to New York lawmakers detailing their “deep concern” about the RAISE Act, calling it “unworkable.” And Leading the Future, the pro-AI super PAC backed by Perplexity AI, Andreessen Horowitz (a16z), OpenAI president Greg Brockman, and Palantir co-founder Joe Lonsdale, has been targeting New York State Assemblymember Alex Bores, who co-sponsored the RAISE Act, with recent ads.

Two organizations, ParentsTogether Action and the Tech Oversight Project, put together Friday’s letter to Hochul, which states that some of the signees had “lost children to the harms of AI chatbots and social media.” The signatories called the RAISE Act as it stands now “minimalist guardrails” that should be made law.

They also highlighted that the bill, as passed by the New York State Legislature, “does not regulate all AI developers – only the very largest companies, the ones spending hundreds of millions of dollars a year.” They would be required to disclose large-scale safety incidents to the attorney general and publish safety plans. The developers would also be prohibited from releasing a frontier model “if doing so would create an unreasonable risk of critical harm,” which is defined as the death or serious injury of 100 people or more, or $1 billion or more in damages to rights in money or property stemming from the creation of a chemical, biological, radiological, or nuclear weapon; or an AI model that “acts with no meaningful human intervention” and “would, if committed by a human,” fall under certain crimes.

“Big Tech’s deep-pocketed opposition to these basic protections looks familiar because we have
seen this pattern of avoidance and evasion before,” the letter states. “Widespread damage to young people —
including to their mental health, emotional stability, and ability to function in school — has been
widely documented ever since the biggest technology companies decided to push algorithmic
social media platforms without transparency, oversight, or responsibility.”
