Risks of using public Wi-Fi

Hackers sometimes try to trick you into connecting to a network labeled “FREE Wi-Fi.” Here’s what you need to know about the potential dangers of public Wi-Fi.

Unencrypted networks

Many public Wi-Fi networks are unencrypted, meaning the data transmitted over them is not secured. This makes it easy for cybercriminals with the right tools to intercept your online activities, including sensitive information like login details, banking data and personal messages.

Malware threats

Connecting to public Wi-Fi can expose you to malware attacks. Malicious actors on the same network can take advantage of security flaws on your device to install harmful software. Some examples are spyware that steals your personal information or ransomware that locks your system or turns your device into a bot for a distributed denial-of-service attack.

Man-in-the-middle attacks

A man-in-the-middle attack occurs when an attacker secretly intercepts communication between two parties, like a user and an app. This allows them to listen in on or alter conversations. On unsecured public Wi-Fi networks, attackers can more easily capture data packets. This potentially gives them access to sensitive information like login credentials, credit card details or private messages. In some cases, they may even modify the data, leading to fraud or data breaches.

Signs of an unsafe network

Hackers often take advantage of public Wi-Fi, but some may go a step further and create fake hot spots under their control. To help you steer clear of these traps, here are some common signs of a rogue Wi-Fi network.

The network name resembles a trusted one: Hackers sometimes set up fraudulent networks that mimic legitimate ones. For example, you might see duplicate network names or be connected to a “home network” when you’re far from home.
“HTTPS” sites appear as “HTTP”: If you’re trying to access a secure website and notice it’s loading as an “HTTP” site instead of “HTTPS,” you may be connected to a fake Wi-Fi hot spot.
The name is generic: Rogue networks often appear in busy areas with vague names like “Free Wi-Fi” to attract unsuspecting users. Legitimate public networks, like those in cafés, usually have more specific names tied to the business.
Unusual behavior: If you experience strange pop-ups, ads, frequent Wi-Fi disconnections or slow speeds, the network you’re connected to could be compromised. To minimize the risk, disconnect immediately and run a malware scan.

Now that you’re aware of the risks and how to recognize an unsafe Wi-Fi network, you can browse more securely.

MISTAKES TO AVOID IF YOU JUST HAVE TO USE PUBLIC WI-FI

Where to find legitimate free Wi-Fi

If you’re looking for reliable spots to access free Wi-Fi, these are some great options.

WiFi Map

WiFi Map has pinpointed millions of free Wi-Fi locations across more than 200 countries. Their website displays nearby free Wi-Fi locations by city on an interactive map. Clicking on a spot will reveal the address, the Wi-Fi hot spot name and any required passwords. There’s also a mobile app available, which is especially handy for accessing passwords. Plus, the app offers an offline map feature, so you can search for hot spots without needing a connection.

Your local library

Many libraries offer free Wi-Fi in addition to computer access. Bring your own device to enjoy internet access at no cost. Check your local library’s website or give them a call to confirm if they provide free Wi-Fi and learn about any connection requirements. While some libraries offer open access, others may ask for a password or require a library card number.

Wi-Fi-FreeSpot Directory

The Wi-Fi-FreeSpot Directory helps you locate free Wi-Fi hot spots in the U.S., Canada, Asia, the Middle East and more. You can search by region, state or country and even narrow your search to specific types of locations, such as hotels, airports, coffee shops or vacation rentals that provide free Wi-Fi.

6 ways to protect your devices for secure public Wi-Fi use

Public Wi-Fi is everywhere, from your favorite coffee shop to the airport. But while it’s convenient, it also comes with some risks, as we mentioned above. Here are six essential tips to help keep your devices and data safe when you’re browsing on public networks.

1) Use a VPN: Accessing the internet in public places, like coffee shops, can put your personal data at risk. A VPN (virtual private network) ensures that your connection is secure and that your information is encrypted. Using a VPN is one of the most effective ways to safeguard your privacy when browsing on public Wi-Fi. It creates a private, encrypted tunnel for your data, protecting you from potential cyber threats. For the best VPN software, see my expert review of the best VPNs for browsing the web privately on your Windows, Mac, Android and iOS devices.

2) Have strong antivirus software: Cybercriminals often exploit the vulnerabilities of public Wi-Fi to distribute malware or intercept sensitive data, making it crucial to protect your devices against such threats. 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. Get my picks for the best 2025 antivirus protection winners for your Windows, Mac, Android and iOS devices.

3) Use two-factor authentication (2FA): Enable 2FA on your accounts to add an extra layer of security, even if someone manages to intercept your password.

4) Set strong passwords: Use complex, unique passwords for each of your online accounts. Get more details about my best expert-reviewed password managers of 2025 here.

5) Keep software updated: Ensure your operating system, applications and security software are up to date to patch known vulnerabilities.

6) Avoid sensitive transactions: Refrain from accessing sensitive information or making financial transactions while on public Wi-Fi.

AVOID PUBLIC WI-FI BY USING YOUR IPHONE AS A HOT SPOT

Kurt’s key takeaways

Finding free Wi-Fi is easy, but it’s important to watch out for security risks. Services like WiFi Map, local libraries and Wi-Fi-FreeSpot can help you find safe hot spots. To protect your data, always use a VPN on public networks and be careful of suspicious networks or activity.

Press Room

All year on The Vergecast, we’ve been tracking the many bizarre and problematic actions of FCC Chairman Brendan Carr. There has been a lot to discuss! Then, this week, ahead of one of our last episodes of the year, Carr appeared in front of the Senate Commerce Committee and spent three hours explaining how he thinks about his job, the FCC, and the state of online communication and entertainment. It was a lot.

On this episode of The Vergecast, we begin with a dissection of Carr’s testimony, his threats against broadcasters, and the ways in which he’s using old ideas about content delivery to get his political way. Nilay and David walk through some of Carr’s most important quotes, explain the history of broadband regulation, and look ahead to how Carr might bring these same tactics to internet regulation next year.

Also, an important housekeeping note: The Vergecast will be live at CES! We’ll be at the Brooklyn Bowl in Las Vegas, at 3:30PM on Wednesday, January 7th. There will be podcasting, and hanging out, and bowling. It’s going to be great, and if you’re going to be in Vegas we’d love to see you there.

Until then, if you want to know more about everything we discuss in this episode, here are some links to get you started, first on Brendan Carr:

AI photo match reunites Texas woman with lost cat after 103 days

NEWYou can now listen to Fox News articles!

Holiday gatherings and year-end travel often lead to a spike in missing pets. Doors open more often, routines shift and animals can slip outside in a moment of confusion.

New Year’s Eve creates loud fireworks, and shelters report some of their busiest nights of the entire year. Amid all that, one Texas family just experienced a heartwarming reunion thanks to an AI photo matching on Petco Love Lost.

How AI photo matching kept the search going

Pam’s 11-year-old indoor cat, Grayson, had never been outside alone. She believes he slipped out while she unloaded groceries at their home in Plano, Texas. The moment she realized he was gone, she acted fast.

She said, “We went up and down the streets day and night. We went online in the neighborhood and on Love Lost. We put up flyers all over the neighborhood. Friends and neighbors were looking for him. I went to the animal shelter, posted him there, and went every day for over a month, hoping to find him.”

Pam uploaded Grayson’s photo to Petco Love Lost right away. She checked her daily match alerts and hoped she would see his familiar face pop up. She told CyberGuy, “I received match alerts almost every day from Lost Love, but never saw Grayson. His profile had been on their site for over 90 days.”

The moment everything changed

Missy, a nearby resident, spotted a thin cat in an alley near her home. She brought him inside, took a picture of him and then turned to Love Lost to see if anyone had reported a missing cat like him.

Missy explained how simple the process felt. “I used Lost Love to reunite them,” she said. “I uploaded a photo of the cat that we found, and it was matched through AI with the photo that the owner uploaded.”

She soon received an AI match alert and learned that the cross street Grayson’s owner, Pam, had listed in her lost post was only a mile from her home. Missy contacted Pam right away.

That message changed everything. “I am sure that if we had not posted his picture and enabled the ability to match the images, we would never have known what happened to Grayson,” Pam said. “And we would not have connected with Missy.”

A long road for an aging cat

Grayson is almost 12 and has never lived outdoors. That made this reunion feel even more emotional, Pam said.

“I am still amazed at Grayson’s journey,” she added. “I look at him and cannot believe he made it through those 103 days. He is almost 12 years old, so he is not a young kitty.”

Pam said she still thinks about what those months were like for him. “[I] guess I will always wonder where he was and how many stops he made before he reached Missy’s loving home,” she said. “He must have known she would take care of him. It takes a special person to take the time to reunite a beloved pet with their family. Missy and her family went above and beyond to reunite us with Grayson.”

Why pet tech matters during the holidays

This season brings joy but also risks for pets. Visitors, travel and loud celebrations create more chances for animals to slip out or feel spooked. Tools like AI photo matching help families act fast when a pet goes missing. Love Lost connects shelters and neighbors in one place so that people like Pam and Missy can find each other.

What to do if your pet goes missing

Losing a pet can feel overwhelming, but taking fast action helps. These steps guide you through what to do right away.

1) Search your home and neighborhood right away

Look in closets, garages and under furniture. Walk your street and ask neighbors to check yards and sheds.

2) Upload your pet’s photo to Petco Love Lost

Take a clear photo and post it on the site. AI photo matching alerts you when a possible match appears. It also helps others contact you fast.

3) Visit your local shelters in person

Shelters update kennels throughout the day. Staff can guide you and help flag your pet’s profile. Go often until you get updates.

4) Post on local community groups

Use neighborhood apps, local Facebook groups and community forums. Include your pet’s photo, last known location and your contact info.

5) Put up flyers right away

Use a large photo and simple details. Place flyers at busy intersections and near schools, parks and businesses.

6) Contact your pet’s microchip registry

If your pet is microchipped, call the registry or log in to your account. Make sure the chip is registered to you, update your contact info and mark your pet as missing so shelters and vets can reach you fast.

7) Stay consistent with your search

Check Love Lost alerts often. Visit shelters and follow up on every lead. Persistence made the difference for Pam and Grayson.

How AirTags can help you find a lost pet faster

While tools like AI photo matching are invaluable after a pet goes missing, prevention and real-time tracking can make an enormous difference during the first critical hours. That’s where Apple AirTags come in. An AirTag isn’t a GPS tracker, but it can still be a powerful recovery tool when used correctly. When attached securely to your pet’s collar, an AirTag uses Apple’s vast Find My network. That network consists of hundreds of millions of nearby iPhones, iPads and Macs that can anonymously and securely relay the AirTag’s location back to you.

If your pet wanders into a neighborhood, apartment complex or busy area, the chances are high that another Apple device will pass nearby and update the location automatically. You won’t know who helped, and they won’t know it was them, but the location can show up on your map within minutes. For indoor cats or dogs that don’t usually roam far, this can be especially helpful. Even a rough location can narrow your search area and save precious time.

Important limits to know: AirTags work best in populated areas. They rely on nearby Apple devices, so coverage may be limited in rural or remote locations. They also don’t update continuously like true GPS pet trackers. That’s why AirTags should be seen as a backup layer, not a replacement for microchipping or dedicated pet trackers.

How to use an AirTag safely with pets

Use a secure, pet-specific AirTag holder that won’t break easily.
Attach it to a breakaway collar for cats and dogs to reduce injury risk.
Make sure Find My notifications are turned on so you get alerts quickly.
Combine it with microchipping and ID tags for the best protection.

Used together, these tools give you multiple ways to reconnect with your pet, whether minutes or months have passed.

TikTok ban: all the news on the app’s shutdown and return in the US

After briefly going dark in the US to comply with the divest-or-ban law targeting ByteDance that went into effect on January 19th, TikTok quickly came back online. It eventually reappeared in the App Store and Google Play as negotiations between the US and China continued, and Donald Trump continued to sign extensions directing officials not to apply the law’s penalties.

Finally, in mid-December, TikTok CEO Shou Zi Chew told employees that the agreements to create TikTok USDS Joint Venture LLC, which includes Oracle, Silver Lake, and MGX as part owners, have been signed, and the deal is expected to close on January 22nd, 2026. His letter said that for users in the US, the new joint venture will oversee data protection, the security of a newly-retrained algorithm, content moderation, and the deployment of the US app and platform.
