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.

The Sonos Era 100 speaker is down to its lowest price in months

Whether you’re considering starting a Sonos speaker setup, or adding to an existing group, the Sonos Era 100 is worth picking up. The compact, capable smart speaker is currently marked down to $189 ($30 off) at a variety of retailers, including Amazon, Best Buy, and directly from Sonos. If you want an even lower price, Sonos is selling refurbished Era 100 speakers for just $134. They come with fresh accessories and packaging, and sport the same one-year warranty as its new speakers.

The wireless speaker has a rich, detailed sound profile, with room-filling audio despite its small size. You might be able to improve the sound further with the Sonos Trueplay feature, which uses either your phone or the speaker’s built-in microphone to automatically tune it to your space. The Era 100 can easily connect with other speakers in the Sonos ecosystem for multi-room play, even with different Sonos models.

The Era 100 has expanded functionality from previous entry-level Sonos speakers, adding in Bluetooth and USB-C wired audio, as well as improved onboard controls. While the speaker features built-in voice assistant support for both Sonos and Alexa, you can flip a switch on its back to cut power to the microphone.

Carnival breach may put your travel data at risk

Carnival breach may put your travel data at risk

NEWYou can now listen to Fox News articles!

Carnival Corporation has confirmed a data breach affecting nearly 6 million people, and the fallout could reach travelers who may not think of themselves as Carnival customers.

The company says the incident involved a social engineering attack on a single user account. In other words, someone fooled an employee and gained access to part of Carnival’s IT system.

For cruise customers, the real concern starts after the breach. Stolen personal details can help scammers write messages that feel far more believable. Here is what may have been exposed, what Have I Been Pwned found in the leaked data and what you can do now to protect yourself.

MAJOR CRUISE LINE HACK EXPOSES SENSITIVE DATA OF NEARLY 6 MILLION TRAVELERS

What information was exposed in the Carnival breach?

Carnival Corporation says the breach began with a social engineering attack on a single user account. An unauthorized actor gained access to a limited part of the company’s IT system. Carnival says it immediately blocked the activity, brought in third-party security experts and alerted law enforcement.

A Carnival Corporation spokesperson told CyberGuy,

“In April, we identified unauthorized access to a limited part of our IT system caused by a social engineering attack on a single user account. We immediately blocked the activity, engaged third-party security experts and alerted law enforcement. Our investigation found certain personal information was illegally accessed. We’re notifying affected individuals and deeply regret any concern this causes. Protecting the privacy and security of personal data is a priority for us and we’ve added new layers of security and monitoring on top of the comprehensive protections already in place. We’ll also continue advancing our defenses against evolving threats.”

State breach reporting shows 5,995,277 people were affected. Carnival says the impacted data varies by individual. However, the company says the information known to be involved includes names, addresses, email addresses, phone numbers, dates of birth and government-issued identification numbers, such as driver’s license numbers and passport numbers.

What Have I Been Pwned found in the leaked Carnival data

Have I Been Pwned also analyzed the data published by ShinyHunters and said it contained 8.7 million records with 7.5 million unique email addresses. That data appeared tied to Holland America’s Mariner Society loyalty program and included names, dates of birth, email addresses, genders, geographic locations, salutations and loyalty program details.

That means this breach could affect you even if you think of yourself as a Holland America customer, not a Carnival customer. Even without a credit card number, this type of data can create problems. Criminals can use it to build fake emails, texts and calls that sound like they came from a real cruise brand. For example, a scammer could mention loyalty points, an upcoming trip, a refund or a cabin upgrade. That one familiar detail may be enough to get you to click.

What ShinyHunters claimed about Carnival

Carnival has not publicly confirmed that ShinyHunters carried out the attack. However, the extortion gang claimed responsibility in April 2026 and said it stole millions of records and internal corporate data.

ShinyHunters has also been tied to broader data theft and extortion activity involving Salesforce customers. The group often pressures companies by threatening to leak or sell stolen information.

The FBI has warned victims not to pay ransom demands from the group. Paying does not guarantee stolen data will be deleted. It also does not stop criminals from trying to extort victims again.

For you, the concern is what happens next. Once your data leaks, scammers may try to use it in emails, texts or calls that sound more believable than the usual junk.

Why the Carnival breach could put you at risk

Travel scams work because they catch you when you are excited, rushed or distracted. Maybe you booked a cruise years ago. Maybe you joined a loyalty program and forgot about it. Maybe you sailed with Holland America, Princess Cruises or another Carnival-owned brand. That old account can still have value to criminals.

Carnival has also dealt with several cybersecurity incidents before. The company disclosed breaches in March 2020 and June 2021 after attackers accessed employee email accounts. Ransomware incidents in August 2020 and December 2020 also exposed personal information tied to Carnival customers and employees.

That history does not mean every Carnival customer will face fraud. But it does show why old travel accounts deserve attention. A loyalty account can reveal more than points. It can connect your name, email, birthday, travel history and brand preferences.

That gives scammers more ways to sound convincing. A fake email may claim your loyalty points are expiring. A text may say you qualify for a refund. A caller may say your account needs verification. Those tricks can lead to stolen passwords, malware, fake payment pages or identity theft attempts.

Ways to stay safe after the Carnival breach

If you receive a Carnival breach notice, read it closely so you know what information may have been involved. Some impacted data may include government-issued identification numbers, so take these steps to lock down your accounts, spot fake cruise messages and reduce the chances that scammers can use your personal details against you.

1) Review Carnival’s offer for credit monitoring

Carnival says it is offering eligible U.S. individuals two years of complimentary credit monitoring. If you receive a notice, use the contact details in that notice or Carnival’s official breach webpage. Do not trust random links in emails, texts or search ads claiming to help you enroll.

2) Change your cruise account passwords

Go directly to the official website or app. Do not click a link from an email or text. Use a strong, unique password for every travel account. A password manager can help you create and store better passwords. Check out the best expert-reviewed password managers of 2026 at Cyberguy.com.

3) Turn on two-factor authentication

Two-factor authentication (2FA) adds another layer of protection. Even if someone steals your password, they still need a second approval. Use an authentication app when possible. Text codes help, but they can be weaker if a scammer tries a SIM swap attack.

4) Watch for fake cruise emails and texts

Be suspicious of messages about refunds, loyalty points, upgrades, cancellations or account verification. Scammers love urgent wording. They want you to click before you think. Instead, go straight to the company’s website or app. Check your account there.

5) Use a data removal service

A data removal service will not undo the Carnival breach. However, it can help remove your personal information from data broker and people-search sites. That can make it harder for scammers to combine leaked breach data with your home address, phone number, relatives’ names or other details found online. 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) Use strong antivirus protection

Breaches often lead to phishing emails with dangerous links or attachments. Strong antivirus protection can help block malicious websites, scam pages and malware before they do damage. Also, keep your phone, tablet and computer updated. Security updates close holes that criminals try to exploit. Get my picks for the best 2026 antivirus protection winners for your Windows, Mac, Android & iOS devices at Cyberguy.com.

7) Do not share personal details with callers

If someone calls and claims to represent a cruise line, do not give out your date of birth, payment details or login codes. Hang up and call the company using a number from its official website.

10 SIGNS YOUR PERSONAL DATA IS BEING SOLD ONLINE

8) Monitor your bank and credit card accounts

Check your statements for charges you do not recognize. Small test charges can show up before larger fraud attempts. Report suspicious activity right away. Many banks also let you lock a card from the app while you investigate.

9) Consider a credit freeze

A credit freeze can block criminals from opening new credit accounts in your name. You can freeze your credit for free with Equifax, Experian and TransUnion. You can also lift the freeze when you need to apply for credit.

10) Review your credit reports

Check your credit reports for accounts, addresses or inquiries you do not recognize. You can get free weekly credit reports from the three major credit bureaus at AnnualCreditReport.com.

11) Watch for misuse of your ID documents

Because Carnival says some impacted data may include driver’s license or passport numbers, be extra cautious with messages asking you to “verify” your identity. Do not upload a photo of your ID through a link in an email or text. Go directly to the official company, bank or government website instead.

12) Consider identity theft protection

Identity theft protection can help monitor your personal information, credit files and financial activity for warning signs of fraud. Some plans also include breach or dark web monitoring, which can alert you if your email address or other personal details appear in known leaks. See my tips and best picks on Best Identity Theft Protection at Cyberguy.com

13) Save the breach notice

Keep a copy of any notice you receive from Carnival. It may explain what information was involved and what support the company offers. Be careful with fake settlement or claim websites. Scammers often create lookalike pages after major breaches.

Kurt’s key takeaways

The Carnival data breach shows why travel accounts need the same care as banking, shopping and email accounts. A cruise may last a week, but the data you shared can stick around for years. Take a few minutes now to tighten your accounts. Change reused passwords, watch for cruise-themed scams and consider freezing your credit if you want stronger protection.

Valve says it’s ready to launch the Steam Machine this summer

Valve says it’s ready to launch the Steam Machine this summer

Valve now says that the delayed Steam Machine PC and Steam Frame VR headset are set to launch sometime this summer. In a Thursday blog post detailing its Verified programs for both pieces of hardware, Valve concludes by saying that “We’re excited for players to try your titles on the new Steam hardware once they launch this summer.”

When the company originally announced the Machine and Frame alongside its new Steam Controller late last year, it said that it would start shipping the new gadgets in early 2026. But in February, the company announced that the ongoing memory and storage crunch had forced it to revisit its pricing and shipping plans. And in March, Valve said in a blog post that it would be “shipping all three products this year” — though that was after the company initially said in the post that “we hope to ship in 2026,” which it removed in an update.

Valve opted to release the Steam Controller on its own, putting it up for sale in early May. For the Machine and Frame, while “summer” isn’t exactly a specific date, it narrows the window for when the products might finally come out.

Ahead of actually launching the devices, Valve is redesigning the Steam store and sharing information about the Verified programs for the hardware so that developers can prepare their games. Like with the Steam Deck, if a game is verified for the Machine or the Frame, the badge signals that the game should work well without any tweaks from the user.

For the Machine, the requirements for a game to be verified are “nearly identical” to what they are for the Steam Deck. With the Machine being “roughly six times as powerful” as the Deck, in theory, many more games will be verified for it. Valve also says that it’s testing “every title on Machine that fell below our performance requirements on Deck.”

For the Frame, Valve’s verified badge will signify games that run well while being played natively on the headset — as opposed to games that work well streamed to the headset, which the Frame is also capable of. “Like Steam Deck Verified, the Steam Frame Standalone Verified program focuses on the experience customers will have with the device out-of-the-box in standalone mode,” Valve says.

Now, we just need Valve to share exactly when the Steam Machine and Steam Frame will be released and how much they might cost. After last week’s price hikes for the Steam Deck, I’m gearing up for sticker shock.
