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

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.

Skullcandy’s bass-boosting Crusher headphones now come with Bose’s ANC

Skullcandy’s bass-boosting Crusher headphones now come with Bose’s ANC

Skullcandy announced a new version of its Crusher wireless headphones today featuring a few of Bose’s audio technologies including its QuietControl ANC and head-tracking spatial audio. The Crusher headphone line differentiates itself from the competition through the use of both full-range and dedicated bass drivers in each ear cup to boost deeper frequencies. Skullcandy admits that approach can result in a loss of audio quality when the bass is heavily boosted, but its new Crusher 1080 ANC are meant to address and improve that with Bose’s help.

Available starting today for $279.99 in black, candy, primer, and cement color options, the new Crusher 1080 ANC feature redesigned drivers with a stiffer diaphragm material resulting in enhanced clarity and detail with less distortion at higher volume. As with previous models in the Crusher line, the bass boosting is entirely adjustable using Skullcandy’s mobile app or the on-headphone controls that now include a more prominent dial on the outside.

The Crusher 1080 ANC will be the first non-Bose headphones to feature that company’s TrueSpatial audio technology with head tracking that works whether you’re stationary or out for a run and its WaveForm audio engine that “keeps audio full, balanced, and smooth.” Skullcandy’s latest will also offer industry-leading noise cancellation with Bose’s six microphone QuietControl ANC tech that adapts as sounds around you get louder or quieter. The Crusher 1080ANC even features Bose’s SpeechClarity that reduces noise so your voice comes through clearly during a call, but they’re not the first third-party headphones to offer it.

Battery life is estimated to be up to 60 hours with ANC turned off, or 50 hours with it on, while a 10-minute rapid charge will keep the Crusher 1080 ANC going for up to four hours if they die. There’s multipoint pairing for connecting and switching between multiple devices, auto reconnect and wear detection that pauses music when you take the headphones off, and a design that folds flat for easier storage. The Crusher 1080 ANC supports Bluetooth 5.3 with LE Audio, low latency audio, and Auracast.

You paid for it. So why is your device showing ads?

You paid for it. So why is your device showing ads?

NEWYou can now listen to Fox News articles!

You paid for the product. So why does it feel like the company still controls the screen? That is the question more of us are starting to ask as smart devices get updated long after we bring them home. A refrigerator can show ads in your kitchen. A car can flash offers on the dashboard. Even a Windows 11 computer can surface promotions before you get to work.

The frustrating part is that this often happens through software updates. You tap update because you want your device to stay secure and work properly. Then one day, the product you bought starts acting like a billboard. This is also why it pays to understand the hidden privacy clauses and settings that come with smart products before those screens start doing things you never expected.

Samsung Family Hub refrigerators started showing ads

Samsung Family Hub refrigerators are sold as connected kitchen hubs. You can use the screen for weather, calendars, grocery lists and other household features. But as we discussed on The CyberGuy Report podcast at CyberGuy.com, that same screen can also become a place for ads after a software update. Samsung began showing ads on some Family Hub refrigerator Cover Screens in the U.S. We reached out to Samsung about this, and a spokesperson provided us with this statement:

“Last year, Samsung piloted a new Cover Screen widget on Family Hub refrigerators in the U.S. The widget rotates through useful information like weather, news, calendar events, and curated ads. After the pilot concluded in March, the widget was launched fully with the same user experience.

Users can turn off the Cover Screen widget, including ads, in the Advertisements tab of the Settings menu (Settings > Advertisements > Cover screen Ads) without impacting any other features or functions. Ads can also be dismissed on the Cover Screens where shown, meaning that the dismissed ad will not appear again during that specific ad’s campaign period. Since the start of the pilot program last October, our review has indicated consumers are finding value in this new widget. The percentage of users who have turned off the feature is in the low single-digits.

A Cover Screen appears when the Family Hub screen is idle, and the widget only appears on the Weather, Color, and Daily Board themes. The widget does not appear on the Cover Screen’s Art or Album themes.”

That answer is important because Samsung says you can turn the Cover Screen ads off without losing other features. Still, the larger point remains. You bought a refrigerator, then a later update added an ad experience to the screen in your kitchen.

How to turn off Samsung Family Hub Cover Screen ads

On the Family Hub screen:

  • Tap Settings
  • Tap Advertisements
  • Tap Cover Screen Ads
  • Turn the switch off

You can also change the Cover Screen theme. Samsung says the widget does not appear on Art or Album themes.

Car screen ads appeared in Jeep, Ram and Chrysler vehicles

Now move from the kitchen to the driveway. Some Jeep, Ram and Chrysler drivers previously saw promotional messages on their infotainment screens through Stellantis’ Uconnect system.

Stellantis, the automaker behind Jeep, Ram, Chrysler and Dodge, says its In-Vehicle Message technology, or IVM, is designed to help the company stay in contact with owners at important points during ownership. The company says it uses IVM for important messages, such as vehicle recalls and vehicle health monitor alerts. Stellantis also confirmed that the earlier pop-up promotions were part of its in-vehicle messaging or Uconnect communication system. However, the company says it has not run the promotional in-vehicle messages referenced in those reports since mid-fall 2025 and has nothing planned for future in-vehicle promotional messages.

At the time those promotional messages were active, Stellantis says owners could opt out by calling customer service or by updating their profile or Message Settings on their vehicle brand’s website account, such as a Ram owner account. That update is important. There are no current promotional in-vehicle messages to opt out of, according to Stellantis. Still, the larger concern remains: modern vehicles are software-driven, and the screen in the middle of your dashboard can be changed long after you drive off the lot.

10 SMALL HOME UPGRADES THAT CAN LOWER YOUR MONTHLY BILLS

Why dashboard messages feel more intrusive

A car screen is different from a phone app or website. You use that display for directions, music, climate controls and vehicle settings. So when a promotional message appears there, it can feel more personal than an ad on a webpage.

To be fair, in-vehicle messaging can serve an important purpose. Recall notices and vehicle health alerts can help owners respond to safety or maintenance issues faster.

However, promotional messages hit differently. You are sitting in a car you paid tens of thousands of dollars for. That screen should help you drive, maintain your vehicle and get where you are going without feeling like another place for a sales pitch.

Windows 11 ads can appear in several places

Then there is your computer. Windows 11 can show promotional content in places that feel like part of the operating system. That includes the lock screen, the Start menu and account-related notifications.

The lock screen can use Windows Spotlight, which displays rotating images along with tips, tricks and notifications. Start menu settings also include areas where Microsoft can show recommendations and account prompts.

Some of these messages may look like helpful notices. Others can feel like upsells. The most annoying ones are the alerts that look urgent, then steer you toward a Microsoft service such as OneDrive backup. Microsoft declined to comment for this story.

  • Click Personalization
  • Click Lock screen
  • Change Windows Spotlight to Picture
  • Turn off Get fun facts, tips, tricks and more on your lock screen

Reduce Start menu suggestions:

  • Go to Settings
  • Click Personalization
  • Click Start
  • Turn off any available toggles for recommendations, tips, suggestions or personalized offers

Limit account-related prompts:

  • Go to Settings
  • Click Personalization
  • Click Start
  • Turn off Show account-related notifications

Microsoft may change wording over time, so look for anything tied to recommendations, tips, suggestions, offers or account notifications. For more Windows settings help, see these Windows 11 tips.

Device screen ads are spreading after you buy

The real problem isn’t one ad on one screen. It is the fact that software gives companies a way to change products after you buy them. A refrigerator used to stay a refrigerator. A car dashboard used to do what it did on the day you drove off the lot. A computer operating system used to feel like the tool you used to get things done.

Now those screens can change later. A company can add a widget, promote a service or push an offer through an update. That does not mean every update is bad. Security fixes are essential. Bug fixes help. New features can be useful. However, ads feel different when they arrive after you already paid for the product. That is why you should keep your devices updated, but also check what changed after the update installs.

What this means to you

Before you buy a smart appliance, connected car or computer, think beyond the hardware. Ask what kind of software controls the screen. Check whether ads, recommendations or promotional content can be turned off.

Advertisement

After setup, go through the settings before you assume the default experience is the only option. Look for menus labeled ads, recommendations, notifications, tips, offers or personalization. If you are setting up a new device, this new electronics setup guide is a good place to start.

Also, pay attention after updates. If a new widget or pop-up appears, do not assume you have to live with it. There may be a buried toggle that turns it off. Most of all, remember that a screen in your home, car or office has value. Companies know that. You should know it too.

Kurt’s key takeaways

This is exactly why we covered this on The CyberGuy Report podcast at CyberGuy.com. It hits a nerve because you already paid for these products, yet companies can still use software updates to claim space on the screens you see every day. Samsung says Family Hub Cover Screen ads can be turned off. Stellantis says its vehicle promotions stopped in the fall of 2025. Windows 11 gives you some settings that reduce tips, suggestions and account prompts. Still, the pattern is hard to ignore. Companies are learning how to keep making money from a product after the sale. That may be great for them, but it can feel pretty lousy when the screen is inside your kitchen, your car or your computer. When you pay thousands of dollars for a product, that screen should work for you instead of becoming another place for a company to sell to you.

Which screen ad would bother you most: one on your refrigerator, one on your computer or one in your car? Let us know by writing to us at CyberGuy.com.

Lucid’s bankruptcy rumor is a bad sign for the EV future

Lucid’s bankruptcy rumor is a bad sign for the EV future

Lucid Motors found itself in a tough bind this week, fending off bankruptcy rumors and watching its stock price plunge as a result. The company quickly denied the report, calling it “completely false” and pointing to its available free cash flow as evidence that it has enough runway to operate into next year.

But despite the swift response, the damage was widespread. The panic immediately bled into competing automakers, pulling down shares of Rivian and Polestar as investors speculated about the long-term survival of EV-only companies in the face of slowing consumer demand and whiplash policy shifts. And it cast a harsh light on the precarity of all three companies and the future of electric vehicles.

The trouble started on Tuesday, when EV trade publication EV reported that restructuring firm AlixPartners had advised Lucid’s board to consider Chapter 11 bankruptcy or a take-private deal. The report also said AlixPartners had encouraged the board to further restructure in the US and Europe and to focus on the Gravity SUV. But while the rest of the media has since reported on Lucid’s denial, no other publication has confirmed EV’s scoop. (For what its worth, EV’s URL is “eletric-vehicle.com,” enshrining the incorrect spelling in its address.)

Lucid confirmed that it had hired AlixPartners, but denied that the firm had made any such recommendations to its board. Instead, AlixPartners would provide advice on “improving execution, strengthening operations and positioning Lucid to realize the full potential of its technology, products and innovation,” Lucid chief communications officer Nick Twork said.

Lucid went a step further, filing a cease and desist order against EV

Lucid went a step further, filing a cease and desist order against EV, claiming that the site’s report directly led to the stock crash. “In short, your actions caused serious injury to a number of investors,” Lucid’s chief legal officer and general counsel, Brian Tomkiel, said in the letter. “And they injured, and continue to injure, Lucid directly.”

Still, the timing was terrible. Lucid is genuinely not in good shape, having lost over $1 billion in the first quarter of the year. The company has also gone through two rounds of layoffs in 2026, having cut 12 percent of staff in February and then 18 percent in June. The company also reduced production at its factory in Arizona in a bid to counteract its high inventory and save money. And there’s been leadership turmoil, with COO Marc Winterhoff departing the company and his position being eliminated entirely in an effort to flatten the structure.

The report sent the stock into freefall, plummeting as much as 50 percent in one of the worst single-day drops in Lucid’s history. And with Polestar and Rivian also catching strays, it’s generally been a glum time for companies not named Tesla trying make a go of exclusively building electric vehicles. Wall Street is panicking because the rumors are aligning with the bad news coming out of these companies’ earnings reports. EV sales are stabilizing, but recovery is still a distant promise. The all-electric future seems further away than ever.

Whether or not Lucid is actually weighing Chapter 11, it’s a sure sign of more turbulent waters ahead. Polestar getting strong-armed out of the US over its Chinese ties has left a lot of EV owners and dealers scratching their heads. Rivian is in an increasingly precarious position thanks to its huge, expensive bet on becoming a mass-market car company with the production of the R2.

All of these companies are increasingly reliant on big stakeholders — Lucid with Saudi Arabia’s Public Investment Fund, Polestar with Geely, and Rivian with Volkswagen — for their future survival. If any of these big backers get cold feet, the future could get really dark really fast.
