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.

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:
- 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
- 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.

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.

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
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.

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 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.
