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.

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.

Instagram is putting every teen into a more private and restrictive new account

Instagram is putting every teen into a more private and restrictive new account

Starting today, Instagram will begin putting new and existing users under the age of 18 into “Teen Accounts” — a move that will affect how tens of millions of teens interact with the platform. The new account type automatically applies a set of protections to young users, and only users 16 years of age and older can loosen some of these settings.

For starters, the accounts of all minors on Instagram will be private by default (not just teens under 16) and will come with some of Instagram’s existing restrictions for young users, such as those that prevent strangers from direct messaging them. But other new features are coming, too, including a Sleep Mode that silences notifications from 10PM to 7AM.

“This really standardizes a lot of the work that we’ve done, simplifies it, and brings it to all teens,” Antigone Davis, Meta’s global head of safety, said during an interview with The Verge. “It provides essentially a set of protections that are in place and are already populated.”

Teens will also get to pick age-appropriate topics they can see more of in Instagram’s recommendations and on the Explore page, such as “sports,” “animal & pets,” “travel,” and more. Instagram will continue limiting the types of content teens see on Reels or on the Explore page. It will also send alerts reminding teens to take breaks from the app.

Parents can now decide when Sleep Mode is enabled and see who their teen has messaged in the past week.

Along with these changes, Instagram is updating some of its parental controls. Parents who want to supervise their teen on the app will be able to see who their child has messaged in the past seven days (without seeing the contents of the messages). They’ll also get to see which topics their teen has chosen to view most often.

While Instagram will let teens over the age of 16 tweak these settings, younger teens will need the permission of a parent to make any changes, like making their account public. Parents will then have to set up Instagram’s supervisory tools to approve the change.

Instagram’s teen accounts are rolling out gradually to users in the US, the UK, Australia, and Canada. Teens who sign up for new accounts will see the change first, followed by existing users within about a week. Meta plans on bringing Teen Accounts to the European Union later this year and will expand the feature across its other platforms in 2025.

“We know some teens are going to try to lie about their age to get around these protections”

But even with these protections coming to all teens on Instagram, questions remain about how well Meta can apply them. “We know some teens are going to try to lie about their age to get around these protections,” Davis says. “Which is why we are going to be building up new opportunities to verify a teen’s age.” Users who attempt to change their age from under 18 to over 18 are already required to record a video selfie, upload their ID, or have other users vouch for their age, but Instagram’s new systems take things a step further.

The platform can now use AI to scan for signals that may indicate a user is under 18. For example, if a user says they’re 18 when creating an account but someone on the app tells them “Happy 14th birthday,” Instagram can use that to inform their real age. “One of the challenges for age broadly is it can be very hard to know,” Davis says. “We have to take a multi-layered approach because there’s no one foolproof way to do this.”

Since Facebook whistleblower Frances Haugen leaked a trove of internal documents detailing the company’s studies on the mental health of teens in 2021, lawmakers have taken a harder stance on social platforms and their effect on kids. Instagram has rolled out a slew of child safety features over the past few years and launched parental controls in 2022 in response. The platform has even agreed to help researchers study its impact on the mental health of teens and young adults.

All of this still hasn’t put lawmakers at ease. Nearly 40 US states are backing the surgeon general’s proposal to put warning labels on social media platforms, while the Senate passed landmark online child safety legislation in July.

Trump is hawking tokens for a crypto project he still hasn’t explained

Trump is hawking tokens for a crypto project he still hasn’t explained

After a disclaimer that nothing we’d hear tonight is financial or legal advice, followed by a 40-minute interview with former President Donald Trump — which touched on the apparent attempt on his life at a Florida golf course, the border, the “evil forces” conspiring against him, and his granddaughter’s foreign language skills — and subsequent conversations with Trump’s sons and associates, the X Space dedicated to announcing Trump’s “crypto platform” more or less got to the point.

The goal of World Liberty Financial, Trump’s new decentralized finance project, is to drive “the mass adoption of stablecoins and decentralized finance,” according to a statement posted on its X account earlier this month. But over the course of the lengthy “announcement” on Monday night, neither Trump nor any of his business partners explained how exactly that would work.

Finally, more than two hours into the stream, Corey Caplan — the co-founder of the decentralized lending platform Dolomite, who is working as an adviser for Trump’s project — said World Liberty Financial would “sell and otherwise distribute governance tokens called WLFI.” The token sales will be limited to “certain persons who would be eligible to participate in transactions that are exempt from registration under US federal securities law,” meaning only accredited investors under Regulation D and Regulation S can buy the token. Three people with knowledge of the project told the New York Times that World Liberty Financial has been pitched as a borrowing and lending platform.

Earlier in the stream, a bevy of Trump relatives and associates described World Liberty Financial as a way of helping the “huge, approachable class of people who have either been debanked … or they just don’t have a bank that they can go to, and they don’t have a bank that will listen to them.”

The details started to emerge a little over an hour and a half into the announcement, when two of Trump’s other business partners — Chase Herro and Zak Folkman — revealed some details of the “crypto platform” Trump and his sons have been teasing for over a month. World Liberty Financial will “onboard as many people through simple products where they can actually start to earn yield on their assets,” said Folkman, the co-founder of Dough Finance, a crypto platform that was hacked earlier this year.

“I think crypto is one of those things we have to do whether we like it or not”

Trump first announced the project in August. “For too long, the average American has been squeezed by the big banks and financial elites. It’s time we take a stand—together. #BeDefiant,” he posted on Truth Social. Aside from a link to a Telegram channel, the post included no other details about the platform or what it entailed. The uncertainty around the announcement has let opportunists — and hackers — take advantage of Trump’s fans. Earlier this month, hackers breached the X accounts of Tiffany Trump and Lara Trump, on which they posted links to a fake World Liberty Financial website announcing that the venture had launched.

Donald Trump Jr. and real estate developer and landlord Steve Witkoff, both of whom are also involved in World Liberty Financial, framed the project as a way of helping underserved and unbanked communities.

“If you want to borrow money today, you have to be almost anointed. You have to be a member of the privileged class,” said Witkoff, who in 2017 purchased the Fontainebleau Resort Las Vegas for $600 million.

Don Jr., who described himself as “still a neophyte” in the crypto space, said decentralized finance can help people who have been excluded from traditional financial markets. The announcement played up a popular fear among the crypto crowd: being debanked, potentially as punishment for political dissent.

“There was a time period where the Trumps, we could’ve picked up the phone and called and CEO of any bank,” Don Jr. said. “We went from being people who would have been the elite in that world to just being, like, totally canceled.” It’s possible that cancellation has more to do with Trump’s history of lying about his wealth or running a scammy for-profit college than it does with his political views.

Despite claims that World Liberty Financial will put “the power of finance back in the hands of the people,” initial reports suggested that its founding token would mostly be distributed to people involved in the project. A white paper obtained by CoinDesk said 70 percent of WLFI would be held by the founding members, team, and service providers.

During the stream, however, Caplan chastised the “fake news media” reports of how the token would be distributed and said approximately 63 percent of the tokens will be sold to the public, while 20 percent would be “reserved for team compensation.”

World Liberty Financial appears to be part of a broader Trump outreach campaign to the crypto community. Trump headlined this year’s Bitcoin Conference in Nashville, Tennessee, where he said he’d never sell the US’s Bitcoin holdings but stopped short of promising to create a strategic Bitcoin reserve. He’s also released four NFT collections, which netted him at least $7.2 million, according to August financial disclosure forms.

It’s evident that Trump, who disappeared from the stream after the first 40 minutes, is the face of a product he knows almost nothing about. He had little to say about cryptocurrency aside from some vague comments about the “very hostile environment” the Securities and Exchange Commission has created for the crypto community — and an admission that politicians know that embracing crypto could help them win voters.

“You’re going to be happy, and you’re going to love your crypto, and as long as you have crypto, you’re happy,” Trump said early in the stream. “I think crypto is one of those things we have to do whether we like it or not.”

Tile’s new AirTag competitors now double as panic buttons

Tile’s new AirTag competitors now double as panic buttons

Tile, one of the leading makers of Bluetooth item finders, has just added a twist — its newest trackers can now send SOS alerts that notify friends, family, and possibly even emergency services.

The 2024 Tile Pro, Tile Mate, Tile Slim, and Tile Sticker are the first new products since Life360 bought the company nearly three years ago, and many facets are unchanged: they should each ring slightly louder and have slightly better water resistance, but the credit card, key fob, and sticker configurations are all roughly the same size and weight. There’s no mention of UWB signals for precision tracking, unlike Apple’s AirTags and Samsung’s SmartTag 2. The Tile Pro is once again the only model that offers a user-replaceable battery.

All but the Tile Sticker now offers an extra 100 feet of quoted Bluetooth range, though, at 350 feet for the Tile and Mate and a full 500 feet for the Pro, and that better connectivity could come in handy if you’re triggering the new emergency alerts.

Tiles could already ring your phone if you double-tap the button; now, a triple tap can optionally send an “SOS Alert” instead. It’ll start a discreet 15-second countdown, after which it’ll send text messages and push notifications to your emergency contacts and even contact Tile’s emergency dispatch center — if you pay for the company’s $14.99 a month Life360 Gold subscription.

The SOS Alerts are a preexisting feature of Life360’s app that you’re basically just remotely triggering over Bluetooth with the Tile’s button instead, so you’ve got to pair your phone with the app and keep it nearby if you want it to work.

It’s also not clear if Life360 will automatically send an ambulance or have a dispatcher call you first, as the company’s website contradicts itself on that point. Tile spokesperson Kelley Garnier says it differs on a case-by-case basis, but either way, a Life360 dispatcher should act immediately.
