National Security Agency is urging Americans to reboot our phones once a week

We spend a lot of time on our smartphones, whether texting, scrolling on social media, checking emails or staying on top of the latest news. We typically only power off our devices when an issue or bug appears or when the battery dies (although that’s not intentional).

However, the National Security Agency recommends powering off and on your smartphone every week to protect yourself from cyberattacks. The spy agency has also listed some general mobile device best practices, which I have been telling you about from time to time.

Why you should restart your phone weekly, according to NSA

The NSA recommends rebooting your smartphone weekly to protect against zero-click exploits, which attackers use to eavesdrop and gather data from phones. While rebooting won’t completely thwart more advanced schemes, many modern cyberattacks involve a sequence of multiple vulnerabilities that need to be exploited in succession. Restarting your phone makes the attacker start over, which can disrupt their progress.

How restarting your phone helps it stay secure

Restarting your phone not only helps you avoid cyberattacks, but it also makes your phone run smoothly. Manufacturers recommend restarting your phone regularly to prevent it from slowing down or freezing.

A quick restart clears out background apps, fixes overheating, resolves memory issues and improves call signals, even if it’s just for a short time. Most importantly, it gives your device a fresh start, which means smoother performance and a longer-lasting battery. This applies to both Android phones and iPhones.

Limitations of restarting your phone

However, the NSA warns that turning your phone off and on again will only sometimes prevent these attacks from being successful.

“Threats to mobile devices are more prevalent and increasing in scope and complexity,” the NSA said while warning that some smartphone features “provide convenience and capability but sacrifice security.”

NSA has more mobile security tips for you

The NSA also advises that you disable Bluetooth when not using it, update your phone with the latest version of the operating system and apps as soon as updates become available and disable location services when not needed. The NSA further warns you not to open email attachments and links.

The spy agency specifically asks you to “not connect to public Wi-Fi networks,” to disable Wi-Fi when not in use and to delete unused Wi-Fi networks. This is solid advice, considering how much cybercriminals use Wi-Fi to exploit you. Earlier in June, I reported on a vulnerability in Windows devices that allows bad actors to hack into your PC just by being connected to the same Wi-Fi network as you.

The NSA also recommends using strong lock-screen PINs and passwords, advising a minimum of a six-digit PIN, as long as your smartphone is set up to wipe itself after 10 incorrect attempts and to lock automatically after 5 minutes of inactivity.

Setting a strong password for every app or software you use and also remembering them can be challenging. I personally use a password manager to generate and manage my passwords, and you can consider using one, too.

HOW TO REMOVE YOUR PRIVATE DATA FROM THE INTERNET

4 additional ways to secure your smartphone

While the tips mentioned above are quite useful, here are a few additional security measures you might consider following.

1) Have strong antivirus software: The best way to protect yourself from clicking malicious links that install malware that may get access to your private information is to have antivirus protection installed on all your devices. This can also alert you of any phishing emails or ransomware scams. Get my picks for the best 2024 antivirus protection winners for your Windows, Mac, Android and iOS devices.

2) Use a VPN: Consider using a VPN to protect against being tracked and to identify your potential location on websites that you visit. Many sites can read your IP address and, depending on their privacy settings, may display the city from which you are corresponding. A VPN will disguise your IP address to show an alternate location. 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.

3) Enable two-factor authentication: Enable two-factor authentication whenever possible. This adds an extra layer of security by requiring a second form of verification, such as a code sent to your phone, in addition to your password.

4) Change your password: You can render a stolen password useless to thieves simply by changing it. Opt for a strong password, one you don’t use elsewhere.

DON’T LET SNOOPS NEARBY LISTEN TO YOUR VOICEMAIL WITH THIS QUICK TIP

Kurt’s key takeaway

The NSA’s advice isn’t a cure-all for your security problems, but I completely agree with the suggestion to turn your devices on and off regularly. It only takes a minute or two each week and is a great habit to develop. You might even want to make it a daily routine, like part of your bedtime routine. Also, it’s important to keep your phone’s software and apps up to date and to avoid clicking on unknown links and attachments.

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.

FIND A LOST PHONE THAT IS OFF OR DEAD

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.”

AI TECH HELPS A SENIOR REUNITE WITH HER CAT AFTER 11 DAYS

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.
