Tired of getting random calls from strangers, wondering whether or not it’s something to be concerned about?

What about when a person calls saying they’ve got a missed phone call from your number?

Or, how about when you see a phone number that looks familiar (perhaps has the same area code), but when you answer, it’s a telemarketer or someone trying to sell you something?

What is going on here?

Phone spoofing, also known as phone number spoofing, is a deceptive practice that scammers use to trick you into answering their calls. By using software or devices, they can make any number appear on the caller ID, even if it belongs to someone else. This can cause problems for both the owner of the spoofed number and the potential victims of the scam.

WHAT IS ARTIFICIAL INTELLIGENCE (AI)?

Here’s what you need to know about phone spoofing and how to stop it so that you can protect yourself (and others) from scammers.

What is phone number spoofing?

Phone spoofing is when scammers get control of your phone number. They can then use your phone number to steal your data or use it to target other people. Instead of a strange phone number or company coming up in your caller ID, they can pass through scam detection by posing as a number you may recognize. This is known as “neighbor spoofing” because scammers will target people within the same — or nearby — area code, which people are less likely to ignore.

But phone number spoofing can be even more sophisticated. Sometimes scammers can spoof the phone numbers of banks, government agencies, police departments, corporations and more. And when most people see those names come up on their caller ID, they generally feel like it’s important or at least an organization they trust, prompting them to answer and not even think twice about who may be on the other line.

What are scammers doing with my phone number?

Once scammers get their hands on your phone number, they can do all sorts of things. In one scenario, they may target you and say you owe a bill for something, prompting you to give up sensitive data about yourself.

In more serious scenarios, they can call your phone and tell you they have your friend or family member who’s in danger and that they need you to send money right away. And with AI voice technology that can replicate voices, this is becoming an even scarier reality. Other times, they use your spoofed number against you, committing identity theft as they’ll have access to your number to get through to your accounts.

How to stop phone number spoofing: When your phone number is spoofed to harm others

If you have a feeling that your phone number has been spoofed, there are some things you can do to stop the situation from getting out of hand.

Step 1: Determine if your phone number has been spoofed

One of the best ways to know that your number has been spoofed is if you’re getting lots of calls from people who tell you they’ve received a missed call or phone call from your number. If you don’t know them and you check your call history to see you’ve never called their number, there’s a good chance that your number has been spoofed and was used to try and trick them.

Step 2: Find out how these scammers hijacked your phone number in the first place

Your number may have been leaked in a data breach. Or you may have your number public somewhere online. You may have answered a spam call accidentally in the past. Or you may have permitted a company to sell your phone number (this is more common with telemarketers). At the same time, data brokers could be intentionally looking for this information, and they’re good at finding it. Next, they hijack your number. They physically do this by:

Port-out method: Once hijackers get your phone number via one of the methods above (in addition to other personal information), they contact your mobile carrier and pose as the account holder, aka you. Once they get in, they request a “port-out” of the phone number, which is when they ask the carrier to transfer your phone number to a new carrier or account. Generally, phone companies should see this as a red flag and ask follow-up questions, but savvy scammers can get around this. Once the port-out is approved, the phone number is activated on their new SIM card and they have total control.

SIM-swap method: This is when a phone spoofer convinces the mobile service provider to issue a new SIM card with your phone number. All they need to do is pop the SIM card into their device to get the same access as the port-out method.

Stealing your physical phone: One of the most straightforward ways to hijack your number is one of the most simple: stealing your mobile device and gaining access to it.

Remember, once they have control of your phone number, they may use it to commit identity theft against you, not just as a phone spoof to harm others.

Step 3: Follow these steps if your phone number has already been spoofed

Even if your phone has been “hijacked,” you can still do something about it. Here’s how:

Apologize to the victims: If people start calling you to let you know they’ve received a scam call from your number, apologize to them right away and let them know that your phone number has been spoofed and that it’s being used to target them. This can help them decide what to do next (which we’ll cover later).

Create a voicemail message: If you’re getting a lot of these calls nonstop, you might want to change your voicemail message to let them know what’s happening. This essentially automates the process, and you don’t need to spend your day answering the phone either.

Notify your mobile carrier: Call your mobile carrier to let them know that you’re confident your phone number has been spoofed. They can help you take the next steps to stop it in its tracks.

Change your phone number: Whether or not your mobile carrier advises you to do so, it might be a good idea to consider changing your phone number. It may not stop scammers from using it to victimize others, but it will help you to stop getting notifications.

Step 4: Prevent scammers from spoofing your phone number in the future

If you end up changing your phone number, you’ll want to be sure that you can prevent scammers from taking your number in the future. Here are a few things you can do:

Don’t publicize your phone number online: Don’t ever provide your phone number to strangers or make it easy for them to get your phone number via a verification scam. Additionally, if you’re creating an account for a new website, and they ask about your phone number, try to avoid giving it. It may be difficult with a bank, for instance, which may use your phone number to verify your identity. But if you can avoid giving your phone number, then you should.

Use a data removal service: There are so many websites that can potentially have your data because you may have unknowingly permitted them to do so. By using a data removal service, you can get your number offline.

While no service promises to remove all your data from the internet, having a removal service is great if you want to constantly monitor and automate the process of removing your information from hundreds of sites continuously over a longer period of time. Check out my top picks for personal data removal services here.

Update passwords on your phone: It may go without saying, but make sure your phone’s passwords are updated. You’ll want to create a strong password for your phone and avoid using the same password for multiple online accounts. Consider using a password manager to securely store and generate complex passwords. It will help you to create unique and difficult-to-crack passwords that a hacker could never guess. Also, enable a PIN or biometrics to get into your phone. This is so that if someone steals your phone, they can’t get access to your information.

Man on a phone call (Kurt “CyberGuy” Knutsson)

Stay calm and steer clear: If you have any hunch that you are being scammed, stay calm, don’t panic and immediately hang up the phone. You can also try another tactic, which is asking the spammer a lot of questions to catch them off guard. Sometimes they’ll realize you’ve set them in a trap and will hang up the phone themselves.

Ultimately — no matter how convincing or familiar the story or phone number is — you want to be sure that you aren’t giving any sensitive data or money to these people. If someone is saying you owe a bill, tell them you will call your bank and get back to them. Even if they already know some of your personal information, do not comply. If it’s legitimate, they’ll understand that you need to double-check.

Alert the appropriate parties: Even if you recognize it’s a scam, sometimes these people are relentless. So, if they continue to call you and harass you nonstop (and it’s from the same number), you have some options:

Notify your mobile carrier: Let them know that you’re confident your phone number has been spoofed. They can help you take the next steps to stop it in its tracks.
Notify the FCC: The Federal Communications Commission is the relevant party you’ll want to contact if you continue to get scam calls, whether they are from phone spoofers or robocalls and telemarketers. You can file a complaint here.
Notify the FTC: If you’ve already, unfortunately, fallen victim to a scam, you can report it to the Federal Trade Commission, here.

Don’t get spammed again: You’ve probably noticed that when you get a call on your phone, it will say “scam likely” in red, prompting you to ignore it. Cellphones these days are pretty good at detecting calls from scammers. This makes it more challenging for scammers to do their dirty work. So, they need another strategy to get around it, which is why they phone spoof. But you can outsmart them, even when they use a familiar-looking number:

Use a spam blocker to keep scammers at bay: To keep spammers and scammers away, install a spam blocker on your phone. Many phone carriers already have this service on the phone (as mentioned above), but there are additional apps you can put on your phone as an extra layer of security, like Truecaller.
Block the number on your phone: Depending on what type of phone you have, you can block the actual number from contacting you again. However, keep in mind that phone number spoofers are savvy and are difficult to keep up with. This method is better if it’s a specific number that keeps trying to contact you.
Block robocalls with apps: Sometimes spammers are robots utilized by telemarketers. Some of those scam-blocking apps work against robocalls. But you can also register your number on the national “Do Not Call Registry” to stop them. You can do this by calling 1-888-382-1222 or visiting www.donotcall.gov/.
Utilize data removal services: If you want robots and other spammers/scammers to stop calling your phone number altogether, some apps and services can help you find and remove your data wherever it is on the Internet. These can also be used to protect yourself against phone spoofing.

Kurt’s key takeaways

While phones may have gotten better at blocking spam calls, scammers will stop at nothing to try and trick you. This is why phone spoofing is a good idea for them; they have a much better chance of getting through spam blockers and connecting with you because you may think it’s safe to answer the phone.

We won’t even be able to stop these scammers 100%. But by knowing what to do if your phone number has been hijacked or you’re being targeted by someone else’s phone number who has been spoofed, you can do your part in making sure these people know we’re onto them.

I’ve been waiting years for Animal Crossing’s best new features

I’ve been waiting years for Animal Crossing’s best new features

I never felt done with my Animal Crossing: New Horizons island. Despite playing every day for two years, and racking up 1,700 hours of playtime, I somehow never finished decorating. I had plenty of ideas for my island, sure, but actually implementing them was another story: The decorating and terraforming systems that helped make New Horizons a huge success are also slow, manual, and cumbersome, and my patience for decorating and redecorating had finally worn thin.

Fast-forward a few years, and a very much unexpected update is coming to finally fix some of those pain points. Update 3.0 is launching on January 15th, 2026, alongside the Switch 2 Edition of New Horizons. And while the paid Switch 2 upgrade has some nice-to-haves (like Joy-Con 2 mouse controls for indoor decorating), it’s the free update that brings all the key new features.

I recently attended a virtual preview for the New Horizons upgrade and update, and there are two caveats: I have not yet played either the Switch 2 version or the new free content myself, and it’s hard to gauge the quality of the Switch 2 version’s visual and performance improvements over a Zoom call. (I still have some unanswered questions about the biggest performance issues on the original Switch, like the choppy frame rate on more densely decorated islands.) But seeing the 3.0 additions in action, it was easy to imagine myself finishing my island — or at least an island.

As shown in the October announcement trailer, update 3.0 makes much-needed quality-of-life fixes. You’ll finally be able to craft multiple items at once, and crafting will pull materials from your overall storage instead of your pockets, meaning you won’t have to do a bunch of inventory management just to craft some decor. Then there’s Resetti’s Reset Service, which can help you clean up entire sections of your island instantly so you don’t have to pick everything up individually in order to redecorate. Some players also noticed a very subtle but potentially impactful change to movement while terraforming that should hopefully make it a smoother process. And then, as if to show off those decorating improvements, Nintendo also added Slumber Islands.

Not to be confused with dreams, New Horizons’ online island-sharing feature, Slumber Islands are extra sandboxes for you to decorate and play with, where you can set the time of day and the weather and magically conjure up any item you have in your in-game catalog to decorate with, similar to the Happy Home Paradise DLC. You can build bridges and inclines instantly by talking to Lloid, rather than going through Tom Nook and waiting (or time traveling) a day. And while it seems like terraforming works the same on Slumber Islands, the apparent addition of strafing while terraforming — instead of having to constantly reorient yourself manually — should help at least a little bit. (It’s the first thing I’m going to test on January 15th, that’s for sure.)

For me, the worst part of decorating in New Horizons was having an idea, ordering all the furniture I’d need for it over the course of days, testing out the design, realizing it did not look the way I envisioned, and facing the tedious process of breaking it all down and starting over again brick by brick — or, at the very least, having to push and pull objects around for a while to see if I could make it work. The design process I saw on Nintendo’s Slumber Island during the preview, meanwhile, seemed quicker and smoother. Trying out an idea or aesthetic in that environment doesn’t sound like such a tall order.

Without any hands-on time, I can’t say if it will actually be noticeably easier to design and decorate with the 3.0 update. But I’m excited by the idea that I can go to my Slumber Island scratch pad and try out my designs before committing to them (and the cost in bells to get it all done) on my main island. And maybe, if I really like how it feels to decorate, I’ll make an entire Halloween-themed Slumber Island — the kind of island I’ve wanted to make for years but never did on my main island, where the seasons continue to change and actively ruin the vibe.

Password manager fined after major data breach

Password manager fined after major data breach

NEWYou can now listen to Fox News articles!

Any data breach affecting 1.6 million people is serious. It draws even more attention when it involves a company trusted to guard passwords. That is exactly what happened to LastPass.

The UK Information Commissioner’s Office has fined LastPass about $1.6 million for security failures tied to its 2022 breach. Regulators say those failures allowed a hacker to access a backup database and put users at risk.

CHECK IF YOUR PASSWORDS WERE STOLEN IN HUGE LEAK

Why the LastPass breach still matters

LastPass is one of the most widely used password managers in the world. It serves more than 20 million individual users and around 100,000 businesses. That popularity also makes it an attractive target for cybercriminals.

In 2022, LastPass confirmed that an unauthorized party accessed parts of its customer information through a third-party cloud storage service. While the incident initially raised alarms, the long-term impact has taken time to fully surface.

The ICO now says the breach affected about 1.6 million UK users alone. That scope played a major role in the size of the fine.

What regulators say went wrong

According to the ICO, LastPass failed to put strong enough technical and security controls in place. Those gaps made it possible for attackers to reach a backup database that should have been better protected.

The regulator added that LastPass promises to help people improve security, but failed to meet that expectation. As a result, users were left exposed even if their passwords were not directly cracked.

Were passwords exposed or decrypted?

There is still no evidence that attackers decrypted customer passwords. That point matters.

Despite the breach, security experts continue to recommend password managers for most people. Storing unique, strong passwords in an encrypted vault is still far safer than reusing weak passwords across accounts.

As one expert noted, modern breaches often succeed after identity access rather than password cracking alone. Once attackers get a foothold, the damage can spread quickly.

Although attackers accessed a backup database, there is no evidence that customer passwords were decrypted. (Kurt “CyberGuy” Knutsson)

Why the LastPass fine is a wake-up call for cybersecurity

The ICO called the LastPass fine a turning point. It reinforces the idea that security is about governance, staff training and supplier risk as much as software.

Users have a right to expect that companies handling sensitive data take every reasonable step to protect it.

Breaches may be inevitable, but weak safeguards are not.

LastPass on the UK data breach

We reached out to LastPass for comment on the UK fine, and a spokesperson provided CyberGuy with the following statement:

“We have been cooperating with the UK ICO since we first reported this incident to them back in 2022. While we are disappointed with the outcome, we are pleased to see that the ICO’s decision has recognized many of the efforts we have already taken to further strengthen our platform and enhance our data security measures. Our focus remains on delivering the best possible service to the 100,000 businesses and millions of individual consumers who continue to rely on LastPass.”

MASSIVE DATA BREACH EXPOSES 184 MILLION PASSWORDS AND LOGINS

How to protect yourself after a password manager breach

Breaches like this are a reminder that security requires layers. No single tool can protect everything on its own.

1) Use a strong password manager correctly

Keep using a reputable password manager. Set a long, unique master password and enable two-factor authentication. Avoid reusing your master password anywhere else.

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.

Check out the best expert-reviewed password managers of 2025 at Cyberguy.com.

2) Rotate sensitive passwords

Change passwords for financial accounts, email accounts and work logins. Focus on services that could cause real damage if compromised.

3) Lock down your email

Your email account is the key to password resets. Use a strong password, two-factor authentication and recovery options you control.

4) Reduce your exposed personal data

Data brokers collect and sell personal information that criminals use for targeting. A data removal service can help reduce what is publicly available about you. 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.

5) Watch for phishing attempts and use strong antivirus software

After major breaches, scammers follow. Be cautious of emails claiming urgent account problems or asking for verification details. 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 at Cyberguy.com.

6) Keep devices updated

Install updates for your operating system, browser and security tools. Many attacks rely on known vulnerabilities that updates already fix.

Kurt’s key takeaways

The fine against LastPass is about more than one company. It highlights how much trust we place in tools that manage our digital lives. Password managers remain a smart security choice. Still, this case shows why you should stay alert even when using trusted brands. Strong settings, regular reviews and layered protection matter more than ever. In the end, security works best when companies and we share the responsibility. Tools help, but habits and awareness finish the job.

Silksong is getting a free expansion next year

Silksong is getting a free expansion next year

It’s still hard to believe that Hollow Knight: Silksong actually came out this year, but now, we all have a new thing to wait for: the game is getting a free expansion in 2026, titled Sea of Sorrow. Team Cherry calls it the game’s “first big expansion.”

“New areas, bosses, tools, and more!” Team Cherry says in a blog post. “Hornet’s adventures continue in our nautically themed expansion, coming free for all players next year. We’ll keep further details a secret for now, but expect additional info shortly before Hollow Knight: Silksong – Sea of Sorrow releases.”

More than 7 million people bought Silksong, according to Team Cherry, and “millions more” played on Xbox Game Pass.

The original Hollow Knight is getting updated, too. Team Cherry is working on a Nintendo Switch 2 Edition of the game that “incorporates all the updates and enhancements that Silksong received on the platform: High frame-rate modes, higher resolutions, and many additional graphical effects.” Players who own the Switch version of the game will get the Nintendo Switch 2 Edition as a free update when it’s available in 2026.

Ahead of that launch, Team Cherry says it will be “updating all versions of the original game for current platforms, adding features and fixing bugs.” Those changes include “full 16:10 and 21:9 aspect ratio support for those of you with Steam Decks or ultrawide monitors,” and PC players can try the new updates in public beta.
