CarGurus breach linked to ShinyHunters exposes 12.4M records

NEWYou can now listen to Fox News articles!

If you’ve ever searched for a car on CarGurus, your personal information could now be circulating online. A hacking group known as ShinyHunters has published what it claims are 12.4 million records taken from CarGurus, a popular auto shopping platform used by millions of people each month.

The leaked data includes names, phone numbers, email addresses, physical addresses and even finance pre-qualification details. While most of the records were already exposed in past incidents, about 3.7 million are newly added to the pile. That means fresh data is now freely available for criminals to download.

149 MILLION PASSWORDS EXPOSED IN MASSIVE CREDENTIAL LEAK

What you need to know about the CarGurus breach

The group behind the leak, ShinyHunters, published a 6.1GB file on Feb. 21, claiming it came from CarGurus. The file allegedly contains 12.4 million user records tied to the U.S.-based auto research and shopping platform CarGurus.

CarGurus operates in the U.S., Canada and the U.K., and its website attracts an estimated 40 million monthly visitors. It allows you to compare vehicles, contact sellers, and, in some cases, apply for financing.

According to Have I Been Pwned, which later added the dataset to its breach database, the exposed information includes email addresses, IP addresses, full names, phone numbers, physical addresses, account IDs, dealer details, subscription information and finance pre-qualification application data, along with outcomes.

Have I Been Pwned reports that about 70% of the data had already appeared in previous breaches. Roughly 3.7 million records are new. CarGurus has not released an official statement confirming the incident and did not respond to media requests for comment. ShinyHunters is known for leaking company data when ransom negotiations fail. The group has recently claimed attacks on major brands across telecom, retail, finance, and tech.

How it works and why it matters to you

ShinyHunters typically gains access by tricking employees, not by smashing through firewalls. In past cases, the group used phone calls or fake login pages to convince staff to hand over credentials. Once inside, attackers can quietly access cloud systems that store customer data.

In some campaigns, they also convinced employees to install malicious apps that granted access to customer databases. That means attackers could read stored information without triggering obvious alarms. If this dataset is legitimate, criminals now have detailed personal profiles tied to car shopping and financing activity, which is valuable.

Finance pre-qualification data is especially sensitive. Even if it does not include full Social Security numbers, it signals that you were actively sharing financial details. That makes you a prime target for follow-up scams, identity theft attempts and fake loan offers. Because the data is publicly available for download, it does not take much skill for criminals to start using it.

“We recently experienced a cybersecurity incident,” a CarGurus spokesperson told CyberGuy. “We promptly responded by securing the affected environment, and we are currently working with a leading cybersecurity firm to investigate. Based on the investigation to date, we believe the activity has been contained and limited in scope. Also, at this time, there are no indications that dealer data feeds, APIs, or core systems or products used by our consumers or dealer partners have been compromised. We remain fully operational, and our services continue without interruption. We will notify any affected individuals in accordance with applicable laws.”

7 ways you can protect yourself from the CarGurus breach

Here’s what you can do right now to reduce your risk and stay ahead of potential scams tied to this leak.

1) Check if your email and passwords are compromised

To see if your email was affected, visit Have I Been Pwned at haveibeenpwned.com. Enter your email address to find out if your information appears in the CarGurus leak. When done, come back here for Step 2.

2) Change your passwords immediately

Start with your most important accounts, such as email, medical and banking. Use strong, unique passwords with letters, numbers and symbols. Avoid predictable choices like names or birthdays. Never reuse passwords. One stolen password can unlock multiple accounts.  A password manager makes this simple. It stores complex passwords securely and helps you create new ones. Many managers also scan for breaches to see if your current passwords have been exposed. Use a password manager to generate strong, unique passwords for every account and store them securely. That way, if one account is exposed, criminals can’t use the same password to access the rest of your accounts. Check out the best expert-reviewed password managers of 2026 at Cyberguy.com.

3) Reduce your online exposure with a data removal service

You can also consider a personal data removal service. 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.

4) Turn on two-factor authentication

If CarGurus or your email provider offers two-factor authentication (2FA), enable it. This adds a second step, like a code sent to your phone, making it much harder for someone to access your account even if they have your password.

5) Watch for finance-related phishing scams

Be extra cautious with emails or texts about car loans, financing approvals, or dealership follow-ups. Do not click links in unsolicited messages. Instead, contact the company directly using the official contact details you find on their website. Also, use strong antivirus software to block malicious links and downloads that often follow phishing campaigns. If attackers use this leaked data to target you with infected attachments, antivirus protection adds another layer of defense.

6) Monitor your credit reports

If you applied for financing, check your credit reports for unfamiliar inquiries or new accounts. Early detection can help you stop identity theft before it spirals. Consider placing a credit freeze if you see suspicious activity.

7) Consider identity theft protection

Identity theft protection services can monitor for unusual activity tied to your name, Social Security number, or financial accounts. They can alert you quickly if someone tries to open a new credit card in your name.

Kurt’s key takeaway

This incident highlights a bigger issue than just one company. When platforms collect detailed financial and personal data, they become high-value targets. If the leaked dataset is authentic, millions of people who were simply shopping for a car now face increased risk of scams. CarGurus has not publicly confirmed a breach. Customers deserve clarity when sensitive financial application data may be involved. Silence only increases uncertainty.

Snap, YouTube, and TikTok settle suit over harm to students

Snap, YouTube, and TikTok settle suit over harm to students

Snap, YouTube, and TikTok have settled the first lawsuit of its kind, alleging that social media addiction has cost public schools massive amounts of money, according to Bloomberg. The suit, filed by the Breathitt County School District in Kentucky, claims that social media has disrupted learning and created a mental health crisis, straining budgets. The terms of the settlement have not been revealed yet, and Meta is still facing a trial in the same suit, which is viewed as a bellwether for over 1,000 similar lawsuits across the country

This follows an earlier case, settled by Snap and TikTok, in which a 19-year-old plaintiff claimed significant personal injury due to addictive social media apps. Google and Meta did not agree to a settlement in that suit, and it eventually went to trial, where a jury awarded the plaintiff $6 million. Meta also recently lost a suit brought by New Mexico’s Attorney General, to the tune of $375 million.

Beyond monetary awards, many, including New Mexico, are pushing for significant changes to social media apps to limit their harm to minors. And this is just the start of what’s shaping up to be a busy year for social media lawsuits. According to Bloomberg, lawyers representing school districts said their “focus remains on pursuing justice for the remaining 1,200 school districts who have filed cases.”

Missed voicemails with no calls? It could be a scam

Missed voicemails with no calls? It could be a scam

NEWYou can now listen to Fox News articles!

It starts quietly. Your phone buzzes. You see a voicemail notification. But your phone never rang. Then it happens again. And again. Before long, your voicemail inbox looks like it’s under attack.

That’s exactly what Mike from Westport, CT, is dealing with right now. He wrote to us saying,

“I am so upset. Every 20 to 30 minutes, I am getting voicemails, but what’s weird is my phone never rings. After blocking the number, it just rolls over to a new source number. When I go to play the message, there is no audio. Is this a scammer just trying to get me to call them back? Not sure what the endgame is here. What can I do to stop this from happening? I really appreciate your help.”

What he is describing is something we’re seeing more often. It may feel random, but there’s a clear pattern behind this voicemail scam and here’s what you need to know to stay safe.

RECEIVING UNEXPECTED INTERNATIONAL CALLS? WHAT YOU NEED TO KNOW

What the silent voicemail scam actually is

This tactic is often called a silent voicemail scam or ringless voicemail spam. Here’s how it works in plain terms:

  • Scammers drop voicemail messages directly into your inbox
  • Your phone never rings, so it feels strange and urgent
  • The message is blank, garbled or extremely short
  • The number changes constantly to avoid blocks

At first glance, it looks like a glitch. That confusion is the point.

What’s really happening behind the scenes

This pattern almost always points to automated robocall systems using caller ID spoofing, not real people manually calling you.

Here’s what’s likely happening:

Advertisement
  • Automated dialing systems are repeatedly hitting your number
  • They use spoofed or constantly changing caller IDs, which is why blocking one number doesn’t stop it
  • Some calls connect briefly, then drop, leaving behind a silent or very short voicemail
  • In some cases, the system is “pinging” your number to confirm it’s active

Once a number is confirmed as active, it can be shared across spam networks and used in future campaigns.

Why scammers leave empty voicemails

It seems pointless, but there’s a strategy behind it.

1) They want you to call back

Curiosity does the work for them. Many people return the call just to figure out what happened. When you call back, you may:

  • Reach a premium-rate number that charges per minute
  • Get routed into a scam call center
  • Confirm your number is active and monitored

2) They test if your number is real

Even if you never call back, your voicemail confirms your number is in use. That makes it more valuable for future scams.

3) They try to bypass spam filters

Because your phone never rings, traditional call filters may not catch it. That lets more of these messages slip through.

Why do the numbers keep changing

You block one number, and another appears minutes later. That’s usually a sign of caller ID spoofing and number cycling. Scammers use software to falsify the number that shows up on your phone and rotate through large batches of numbers to stay ahead of blocks and spam filters. Some of those numbers may be completely fabricated, while others may belong to real people whose caller ID information is being misused. Many of those numbers are:

  • Fake
  • Reassigned or temporarily used
  • Tied to real people who have no idea their number is being spoofed

Blocking a single number can still be worth doing, but it usually will not stop the campaign by itself because the caller can keep switching numbers.

Is your phone being hacked?

This is one of the first things many people worry about. In most cases, no. These silent voicemails are more likely to be part of a scam call or robocall campaign than a sign that your phone has been hacked. Scammers can use tactics such as caller ID spoofing and ringless voicemail to reach you without making the call feel normal.

The bigger risk isn’t your phone itself. It’s how the scam tries to get you to respond. Calling back, pressing prompts or engaging with the message can confirm that your number is active and may expose you to more scam attempts. The FTC specifically advises people to hang up or delete the voicemail and not call back unknown numbers.

How to stop silent voicemail scams

You don’t have to just put up with it. There are ways to reduce or stop these messages. 

1) Do not call back unknown numbers

Even if it feels harmless, skip it. If it’s important, the caller will leave a real message.

2) Enable spam call filtering

On iPhone and Android, turn on built-in call filtering and silence unknown callers. This helps reduce future attempts.

How to enable spam call filtering 

On iPhone (latest iOS)

Apple now gives you two strong options: Silence Unknown Callers and Call Screening.

Option 1: Silence unknown callers

Advertisement
  • Open Settings
  • Tap Apps
  • Tap Phone
  • Scroll down and turn on Unknown Callers

This sends calls from numbers not in your contacts straight to voicemail without ringing.

Option 2: Turn on Call Screening (recommended)

  • Open Settings
  • Tap Apps
  • Tap Phone
  • Scroll down and under Screen Unknown Callers, select Ask Reason for Calling

This feature prompts unknown callers to say who they are before your phone rings, which filters out many spam calls automatically.

Optional: Enable spam identification

  • Go to Settings
  • Tap Apps
  • Tap Phone
  • Tap Call Blocking & Identification
  • Tap Business Call Identification
  • Make sure it is set to ON

This allows your iPhone to show verified business names and logos for legitimate callers when available.

On Samsung 

Samsung combines spam protection with AI call screening.

Settings and feature names may vary depending on your Samsung model, carrier and software version.

Option 1: Turn on spam protection

  • Open the Phone app
  • Tap the three-dot menu (top right)
  • Tap Settings
  • Tap Caller ID and spam protection
  • Toggle it ON

This flags suspected spam calls before you answer.

Option 2: Block unknown callers

  • Open the Phone app
  • Tap the three-dot menu (top right) 
  • Tap Settings
  • Tap Block numbers
  • Turn on Block calls from unknown numbers 

This stops hidden or unidentified numbers from ringing your phone.

Option 3: Enable Call Screen (best option)

  • Open the Phone app
  • Tap the three-dot menu (top right)
  • Tap Settings
  • Tap Bixby Text Call or just Text Call
  • Toggle it ON

This lets your phone answer unknown calls with AI and show you what the caller says in real time.

One important reality check: Even with these turned on, some calls may still go to voicemail. That’s because voicemail is controlled by your carrier, not your phone.

HOW TO STOP SPAM MAIL, POLITICAL TEXTS AND EMAIL SPAM FOR GOOD

3) Use a call-blocking app

Apps can spot patterns faster than manual blocking and stop repeat offenders. Many of these apps can also identify known scam numbers and automatically block high-risk calls, helping reduce how often your phone gets hit.

4) Contact your carrier

Many carriers offer network-level spam blocking. Ask about tools that block ringless voicemail or robocalls.

5)  Use a data removal service

If your number keeps getting hit, it may already be circulating on marketing lists or data broker sites. These data removal services scan for your personal information and help remove it from databases that scammers often tap into. Cutting down where your number appears can reduce how often you get targeted over time. 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) Report the activity

You can report unwanted calls and voicemails to the Federal Trade Commission at reportfraud.ftc.gov or by calling 1-877-FTC-HELP (1-877-382-4357). Reports help track and shut down large scam campaigns.

7) Protect your number going forward

Avoid posting your phone number publicly. The less exposure it has, the harder it is for scammers to target you.

8) Register your phone number on the National Do Not Call Registry at donotcall.gov/

This can help reduce telemarketing calls from legitimate businesses, but it unfortunately won’t stop scammers, illegal robocalls, or exempt organizations (like charities and political groups) from calling you. Scammers often ignore the registry and use tactics like number spoofing to bypass it. Want to know more about why your phone still won’t stop ringing and what you can do about it?  Check out our article on the ‘Do Not Call’ list loophole.

Kurt’s key takeaways

Silent voicemails are designed to mess with your instincts. They rely on curiosity and confusion, not sophisticated hacking. The best move is simple. Don’t engage. Let them hit a dead end. Over time, that tells the system your number isn’t worth the effort.

Xbox is now XBOX

Xbox is now XBOX

Xbox just allcapsmaxxed: Meet XBOX. This isn’t a joke; Microsoft appears to be actually rebranding Xbox to XBOX. Asha Sharma, Xbox CEO, ran a poll on X earlier this week, asking fans whether Microsoft should use Xbox or XBOX. The results were in favor of XBOX, and the company has now renamed its X account.

Curiously, the Threads and Bluesky accounts for Xbox haven’t been renamed yet, but if Microsoft is going ahead with a rebranding then I expect those will change soon. I asked Microsoft to comment on this potential Xbox rebranding and the company simply referred me to Sharma’s post.

The use of all caps for Xbox is a return to original form, though. Microsoft’s first Xbox logo for its console was all caps, and the company has favored using similar capped versions for the Xbox 360, Xbox One, and Xbox Series X / S console logos.

The apparent rebranding comes just a few weeks after Sharma scrapped Microsoft Gaming and renamed Microsoft’s gaming division back to Xbox. It’s part of Sharma’s continued promise of a “return of Xbox,” which has involved fan-focused console updates, a new Xbox logo, Game Pass pricing changes, and lots more in recent weeks.
