Is your smartphone spying on you without you even knowing it?
Researchers at MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) recently revealed a startling new privacy threat.
Our smartphones’ ambient light sensors might be turned into makeshift cameras.

From brightness adjustment to privacy invasion
Ambient light sensors are commonplace in smartphones, primarily used to adjust screen brightness according to environmental lighting. However, CSAIL researchers have demonstrated that these sensors could potentially be repurposed to capture images of a user’s surroundings.
By employing a computational imaging algorithm, they managed to recover environmental images from the perspective of the phone’s screen, utilizing only the light intensity data from these sensors.

A comprehensive privacy threat
The implications of this discovery are far-reaching.
“Ambient light sensors are tiny devices deployed in almost all portable devices and screens that surround us in our daily lives,” notes Princeton University professor Felix Heide. The study underscores a privacy threat that spans a broad spectrum of devices, previously underestimated in its potential impact.
WHAT IS ARTIFICIAL INTELLIGENCE (AI)?

Gesture interception and interaction capture
Beyond static images, the study suggests that ambient light sensors could intercept user gestures, like swiping and sliding, capturing interactions with phones during activities such as video watching. This capability challenges the belief that ambient light sensors are harmless in terms of private data exposure.

The call for tighter permissions
Yang Liu, a Ph.D. candidate at MIT EECS and CSAIL, warns that ambient light sensors, in conjunction with display screens, can capture our actions without consent, posing significant privacy risks. The researchers urge operating system developers to tighten permissions for these sensors, reducing their precision and sampling rate.

Looking ahead: Designing for privacy
To mitigate these security concerns, the study proposes granting users control over ambient light sensor permissions akin to camera permissions. Additionally, future device designs might include ambient light sensors positioned away from the user, such as on the side of the device, to prevent unauthorized visual data capture.
While the study’s findings prompt a reevaluation of sensor permissions and design, it’s equally important to recognize the broader context of smartphone security vulnerabilities. Let’s delve into the realm of spyware, another pressing concern where even the most vigilant users can find themselves compromised.

Understanding spyware vulnerability on your smartphone
You might not realize it, but your phone could be more exposed to spyware than you think. Just a small slip-up while you’re browsing the web, and you could accidentally invite a cyber-spy into your life. If you’re an Android user, be extra cautious. Your phone is usually more at risk than iPhones.
But here’s the kicker. Even if you’re super careful, you’re not totally out of the woods. If you don’t update your phone’s software regularly or if you’ve jailbroken it, you’re playing with fire. Here are some telltale signs of spyware on your phone.

The telltale sign of spyware on your phone
Is your phone acting strange? Here are the telltale signs of spyware on your device.
Unusual noises: Beeping, faint voices or static during calls might not just be network issues. They could signal an eavesdropping attempt.
Performance lags: If your phone suddenly slows down or the battery drains rapidly, spyware might be hogging your resources.
Sensors activate unexpectedly: Modern smartphones signal when cameras and mics are in use. If this happens sans your input, investigate promptly.
Mysterious apps and files: New, unrecognizable apps or files might indicate that your phone’s security has been breached.
Excessive pop-ups and spam: An uptick in ads, error messages or scam texts may be adware, a common companion to spyware.
Overheating issues: Like performance lags, overheating can suggest that spyware is overworking your phone’s internals.

Several steps you can take to protect yourself from spyware on your smartphone
1. Have good antivirus software: Yes, antivirus protection can help detect and disable spyware on your smartphone. The best way to protect yourself from clicking malicious links that install malware that may get access to your private information is to have antivirus protection installed on all your devices. This can also alert you of any phishing emails or ransomware scams. Get my picks for the best 2024 antivirus protection winners for your Windows, Mac, Android & iOS devices.
2. Remove unfamiliar apps and files: If you suspect your phone has been hacked, promptly remove any unfamiliar apps.
3. Restart your device: Rebooting your phone can sometimes stop spyware from running.
4. Update to the latest software: As mentioned before, updates can patch vulnerabilities.
5. Be cautious when browsing: Avoid clicking on suspicious links or downloading files from untrusted sources.
6. Update your phone regularly: Updates often include security patches that can help protect your device from spyware and other vulnerabilities.
7. Don’t jailbreak your phone: Jailbreaking removes security restrictions that can make your phone more susceptible to spyware.
8. Look for unusual activity: This includes unusual noises during calls, performance lags, unexpected sensor activation, mysterious apps or files, excessive pop-ups and overheating.
9. Delete unwanted or unused apps: Some apps use your device’s camera and microphone and collect your data even while it is not in use. Getting rid of unused apps frees up storage space on your phone and declutters your lock screen. It can also eliminate one more potential app that might be collecting information from you unknowingly.
On an iPhone:
- Hard press the app icon of the app you want to delete
- Select Remove App
- You’ll be prompted to confirm your decision in the next window by tapping Delete App
- Then again by tapping Delete
On an Android:
- Go to the Google Play Store app
- At the top right, tap the Profile icon
- Select Manage apps & devices, click Manage
- Select name of the app you want to delete
- Select Uninstall
Android settings may vary based on the manufacturer’s settings.
While it may seem like an extra effort to review and change your apps’ permission settings, it’ll give you more peace of mind knowing which apps have access to specific device functions and data. Most devices now have a dedicated part of their settings to view which apps are using the different functions of your phone and what data it has access to.
10. Changing camera settings: It may seem simple to just give access to your camera to certain apps. This way, you can easily use the camera function whenever you pull up the app to use. There are, however, apps that do not need access to your camera to function. Does your navigation app need access to your camera even when it is not in use? Take back control of your camera by using the steps below to find out which apps have access to your camera and turn it on or off.
On an iPhone:
- Go to Settings
- Scroll down and select Privacy or Privacy & Security
- Select Camera
- You can see which apps have access to your camera. Of course, you can leave the apps where it makes sense to have access to your camera toggle on. For apps that do not, you can toggle access off (it will be grayed out)
On an Android:
Android settings may vary based on the manufacturer’s settings.
- Open Settings
- Select Apps
- Select the app you want to change (If you can’t find it, select ‘See all apps’)
- Select Permissions to view if you allowed or denied any permissions for the app
- To change a permission setting, select it, then choose Allow only while using the app, Ask everytime or Don’t allow
11. Restrict camera and microphone permissions: Restricting camera and microphone permissions can make it more difficult for spyware to access these features.
On an iPhone:
- Go to Settings
- Scroll down and select Privacy or Privacy & Security
- Select Microphone
- You can see which apps have access to your microphone. Of course, you can leave the apps where it makes sense to have access to your microphone toggle on. For apps that do not, you can toggle access off (it will be grayed out)
On an Android:
Android settings may vary based on the manufacturer’s settings.
- Open Settings
- Select Apps
- Select the app you want to change (If you can’t find it, select ‘See all apps’)
- Select Permissions to view if you allowed or denied any permissions for the app
- To change a permission setting, select it, then choose Allow only while using the app, Ask everytime or Don’t allow

Tim Cook will still be Apple’s Trump whisperer
Though Tim Cook is shedding his CEO title for the role of Apple’s executive chairman, it appears he’ll keep one of his most important duties: that of the company’s Trump whisperer.
“As executive chairman, Cook will assist with certain aspects of the company, including engaging with policymakers around the world,” Apple writes in a press release. Translation: he’s sticking around to deal with thorny political relationships — in particular the one with President Donald Trump.
Throughout his tenure, Cook has navigated Apple through tricky political terrain. He’s had to balance the company’s massive business interest in China with US policymakers’ concerns, and he’s worked to appease Trump for favorable regulatory decisions, without alienating too many Apple employees and customers in the process.
Cook has navigated Apple through tricky political terrain
The task of wooing Trump has repeatedly placed Cook in embarrassing situations: Cook showed the president around a factory in Texas in 2019, where Trump wrongly boasted that because of his policies, Apple was building a new manufacturing plant in the US. Last year, he presented Trump with a symbolic gift of “Made in the USA” glass from Apple supplier Corning set in 24-karat gold.
Recently, Cook took criticism from Trump critics for attending a movie night at the White House, for a screening of the documentary Melania, the same day that Alex Pretti was killed by federal agents on the streets of Minneapolis during a protest against Immigration and Customs Enforcement. Cook later vaguely referred to the “events in Minneapolis,” and referenced a “good conversation with the president.”
As Apple’s senior vice president of hardware engineering John Ternus takes over as CEO, the company will need to overcome significant policy challenges, including global efforts to regulate AI, and a push for app stores to verify user ages. Lucky for Ternus, Cook will still be there to take on that job.

6 crypto scam scripts criminals use to steal your money
NEWYou can now listen to Fox News articles!
Just about every day, we receive emails from readers who have encountered new scams. Many involve cryptocurrency. The pattern keeps repeating. Someone receives a message that feels urgent, emotional or exciting. The person on the other end sounds confident and persuasive. Before long, the victim is being asked to send money through cryptocurrency. Once the money is sent, it often disappears forever.
Cryptocurrency appeals to scammers for a simple reason. Transactions move quickly, often cross international borders and usually cannot be reversed once completed. That combination makes crypto payments especially attractive to criminals.
Kate recently wrote to us with a great question.
“Could you do an article that illustrates the scripts used by scammers to lure people to send money using cryptocurrency. Those scripts must be very convincing to get so many reasonably intelligent people to send money. Maybe five or six examples of the scripts, so people, especially seniors, will know what to watch out for.”
Kate is absolutely right. These scripts are convincing because scammers practice them constantly. They use psychology, urgency and emotion to push people toward quick decisions.

The investment opportunity script
This script often begins with a friendly introduction through social media, email or even a text message.
Example script:
“Hi, I work with a private investment group that trades cryptocurrency. We’ve helped many people earn steady returns. If you invest $500 today, you could earn $5,000 within weeks. I can show you proof of other investors’ success.”
The scammer may send fake screenshots of profits. Some will even allow a small withdrawal early on to build trust. Eventually, they push the victim to send larger deposits. Once the larger transfer is sent, the account suddenly stops responding.
The romance crypto script
This scam often starts with a simple message on a dating app, Facebook or Instagram. The first contact is friendly and low-pressure.
Example initial script:
“Hi, insert name here, I hope you don’t mind me saying hello. Your profile caught my attention, and you seem like a very kind person. How has your day been?”
After a few days of conversation, the scammer begins sharing details about their life. They often claim to work overseas as an engineer, doctor or business owner. Eventually, they mention cryptocurrency trading as something they do on the side.
Later message in the script:
“I have been doing some short-term crypto trading after work. It has helped me save a lot faster. If you are interested, I can show you the platform I use. It is very easy to start with a small amount.”
From there, the scammer guides the victim to a fake trading site or asks them to transfer cryptocurrency to a wallet they control. At first, the account may show fake profits. The victim believes the investment is working and sends more money. Eventually, the victim cannot withdraw any money.

The government impersonation script
Scammers often pretend to represent government agencies or law enforcement.
Example script:
“This is an urgent notice regarding your tax account. Your Social Security number has been linked to suspicious activity. To prevent legal action, you must verify your identity and pay the outstanding balance today using cryptocurrency.”
Government agencies do not demand payment through cryptocurrency. The goal is to scare you into acting quickly without checking the facts.
The tech support emergency script
This scam often begins with a pop-up warning or an unexpected phone call.
Example script:
“Your computer has been compromised by hackers. Your bank information may be at risk. To secure your system, we need you to transfer funds temporarily into a protected cryptocurrency wallet.“
The scammer claims the funds will be returned once the system is secure. In reality, the transfer moves the money directly to the criminal.
The crypto giveaway script
This scam frequently appears on social media or video platforms.
Example script:
“We are celebrating a new crypto launch. Send 0.1 Bitcoin to this wallet, and we will immediately send back double the amount.”
The message may appear to come from a well-known company or public figure. The wallet address belongs to the scammer. Anyone who sends funds receives nothing in return.
The fake recovery service script
This scam targets people who have already lost money.
Example script:
“We specialize in recovering stolen cryptocurrency. Our investigators located the wallet that received your funds. To begin the recovery process, we require a small crypto payment to unlock the legal tracing tools.”
The victim believes they are hiring professionals to recover their money. Instead, they are being scammed again.
Why these scripts work so well
These scams succeed because they exploit human behavior. First, they create urgency. Victims feel pressured to act quickly.
Second, they create trust. The scammer may sound friendly or sympathetic.
Third, they promise rewards. Investment scams offer profits that feel life-changing.
Finally, cryptocurrency adds confusion. Many people are still learning how it works. Criminals take advantage of that uncertainty.
Understanding these scripts is the first step to protecting yourself. Once you recognize the patterns scammers use, it becomes much easier to stop the conversation before money is involved.
How to protect yourself from crypto scams
Crypto scammers rely on urgency, trust and confusion to pressure victims into sending money. These practical steps can help you recognize warning signs and avoid costly mistakes.

1) Slow down when money is involved
Scammers depend on urgency to push victims into fast decisions. If someone pressures you to send money immediately, treat it as a warning sign. Pause the conversation and verify the situation independently. Contact the company, agency or person through a known phone number or official website. Taking even a few minutes to step back can stop a scam before money leaves your account.
2) Never send cryptocurrency to someone you do not know
Cryptocurrency transactions work very differently from credit cards or bank transfers. Once funds are sent, they usually cannot be reversed. Scammers prefer crypto because it moves quickly and often crosses international borders. If someone asks for payment through Bitcoin, Ethereum or another digital currency, assume the request is suspicious until proven otherwise.
3) Verify investment opportunities independently
Many crypto scams promise fast profits or guaranteed returns. Legitimate investments never guarantee profits. Before investing, search the company name, website and contact information online. Look for warnings from regulators or consumer protection agencies. If you cannot find reliable information about the company, that is a major red flag.
4) Use strong antivirus software on your devices
Scammers frequently use phishing links, fake websites and malicious downloads to trick victims. Strong antivirus software can help detect these threats before they cause damage. Strong antivirus software can warn you about suspicious websites, block malicious downloads and help stop phishing attempts that try to steal your financial information. Get my picks for the best 2026 antivirus protection winners for your Windows, Mac, Android and iOS devices at Cyberguy.com.
5) Reduce the personal information scammers can find online
Scammers often research their targets before sending messages. They may gather details from public records, social media or data broker websites. Limiting the amount of personal information available online can make it harder for criminals to craft convincing messages. Removing your data from people search sites with a data removal service can reduce the chances of becoming a target. 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) Be cautious with online relationships
Romance scams often begin with friendly messages on dating apps or social media. Over time, the scammer builds trust and eventually introduces a crypto investment opportunity. If someone you have never met begins discussing cryptocurrency investments or asks you to move money, take a step back. Real relationships do not require financial transfers to strangers.
7) Never trust screenshots or profit dashboards
Crypto scammers often show screenshots of trading accounts that appear to generate large profits. These images are easy to fake or are displayed on fraudulent websites controlled by the scammer. Even if a platform shows profits, it does not mean the money exists. If you cannot withdraw funds easily through a verified exchange, the investment may be fake.
8) Watch for requests to move conversations off the platform
Many scams begin on social media, dating apps or messaging platforms. After the first contact, scammers often ask victims to continue the conversation on WhatsApp, Telegram or another private messaging app. Moving the conversation helps them avoid detection by the original platform. If someone quickly asks you to switch apps, treat it as a warning sign.
9) Talk to someone you trust before sending money
Scammers often isolate their victims and discourage them from discussing the situation with friends or family. Before sending cryptocurrency or making a large investment, pause and talk to someone you trust. A second opinion can often spot warning signs that are easy to miss when emotions are involved.
What to do if you already sent cryptocurrency to a scammer
If you believe you sent cryptocurrency to a scammer, act quickly. Contact the exchange or platform you used to send the funds and report the transaction immediately. Some exchanges may be able to flag the receiving wallet and help investigators track suspicious activity.
You should also report the scam to the FTC at reportfraud.ftc.gov and notify your local law enforcement agency. If the scam began on a social media site, dating app or messaging platform, report the account there as well so it can be investigated and removed.
While recovering funds can be difficult, reporting the incident can help authorities identify larger fraud networks and potentially prevent others from becoming victims.
Kurt’s key takeaways
Cryptocurrency scams continue to grow because the scripts are polished and carefully tested. The criminals behind them understand human psychology. They know when to apply pressure, when to build trust and when to promise rewards. Recognizing these patterns is one of the most powerful ways to stop them. When you know the script, the scam becomes much easier to spot.
Have you ever received a message that tried to convince you to send cryptocurrency, and did the script almost sound believable? Let us know by writing to us at Cyberguy.com.

This pasta sauce wants to record your family
As if there weren’t already enough devices listening in on everything being said in your home, Prego, the pasta and pizza sauce brand, is releasing a device designed to record everything said around the dinner table for posterity. The Connection Keeper, which looks like an oversized pasta jar lid, was created in collaboration with StoryCorps, the nonprofit organization focused on preserving the stories of Americans in a collection housed at the Library of Congress’ American Folklife Center. There’s no AI, Wi-Fi, or Bluetooth, but you can optionally upload recordings to StoryCorps’ website to make them easier to share with family.
Prego says the goal of the device is to encourage families to make memories through conversation during dinner instead of staring at their phones — but only for a small number of families. The company is only planning to make less than 100 of them. The Connection Keeper will be available for purchase online starting on April 27th for $20 as part of a bundle that includes the device, a jar of Prego sauce, spaghetti noodles, and a deck of cards featuring conversation prompts and ideas.
Using the device is as easy as plopping the Connection Keeper down in the middle of everyone at the table and pressing one button to start recording. Using a pair of microphones, it captures CD-quality audio to a 16GB microSD card for up to eight hours when fully charged.
When dinner’s over, the recordings can be transferred to a computer over USB-C and then uploaded to a dedicated microsite created by StoryCorps where they’re preserved and accessible only by the uploader, unless they choose to share them with other StoryCorps users or the general public. You even have the option to archive them within the Library of Congress, which makes them public automatically, so hopefully your family talks about more than just stealing brainrots.
The recordings can be accessed on a smartphone through the StoryCorps app, but Prego intentionally left phones out of the rest of the process to discourage their use at the table. It’s also why the Connection Keeper lacks a screen. The goal was to minimize interactions with the device so family members instead focused on talking with each other.
