Thousands of iPhone apps expose data inside Apple App Store

NEWYou can now listen to Fox News articles!

Apple often promotes the App Store as a secure place to download apps. The company highlights strict reviews and a closed system as key protections for iPhone users. That reputation now faces serious questions.

New research shows that thousands of iOS apps approved by Apple contain hidden security flaws. These flaws can expose user data, cloud storage and even payment systems. 

The issue is not malware; it’s poor security practices baked directly into the app code.

APPLE WARNS MILLIONS OF IPHONES ARE EXPOSED TO ATTACK

Cybernews researchers found that many iOS apps store sensitive secrets directly inside app files, where they can be easily extracted. (Kurt “CyberGuy” Knutsson)

What researchers discovered inside iOS apps

Security researchers at Cybernews, a cybersecurity research firm, analyzed the code of more than 156,000 iPhone apps. That represents about 8% of all apps available worldwide.

Here is what they found:

  • Over 815,000 hidden secrets inside app code
  • An average of five secrets per app
  • 71% of apps leaked at least one secret

These secrets include passwords, API keys and access tokens. Developers place them directly inside apps, where anyone can extract them. According to Cybernews researcher Aras Nazarovas, this makes attackers’ jobs much easier than most users realize.

What are hardcoded secrets in simple terms?

A hardcoded secret is sensitive information saved directly inside an app instead of being protected on a secure server. Think of it like writing your bank PIN on the back of your debit card. Once someone downloads the app, they can inspect its files and pull out those secrets. Attackers do not need special access or advanced hacking tools. Both the Cybersecurity and Infrastructure Security Agency and the Federal Bureau of Investigation warn developers not to do this. Yet it is happening at a massive scale.

Cloud storage leaks exposed huge amounts of data

One of the most serious problems involves cloud storage. More than 78,000 iOS apps contained direct links to cloud storage buckets. These buckets store files such as photos, documents, receipts and backups. In some cases, no password was required at all. Researchers found:

  • 836 storage buckets are fully open to the public
  • Over 76 billion exposed files
  • More than 406 terabytes of leaked data

This data included user uploads, registration details, app logs and private records. Anyone who knew where to look could view or download it.

Firebase databases were also left open

Many iOS apps rely on Google Firebase to store user data. Cybernews found more than 51,000 Firebase database links hidden in app code. While some were protected, over 2,200 had no authentication. That exposed:

  • Nearly 20 million user records
  • Messages, profiles, and activity logs
  • Databases that are mostly hosted in the U.S.

If a Firebase database is not locked down, attackers can browse user data like a public website.

Payment and login systems were at risk too

Some of the leaked secrets were far more dangerous than analytics or ads. Researchers discovered secret keys for:

Advertisement
  • Stripe, which handles payments and refunds
  • JWT authentication systems that control logins
  • Order management tools used by shopping apps

A leaked Stripe secret key can allow attackers to issue refunds, move money or access billing details. Leaked login keys can let attackers impersonate users or take over accounts.

AI and social apps were among the worst offenders

Some of the apps with the largest leaks were related to artificial intelligence. According to VX Underground, security firm CovertLabs identified 198 iOS apps leaking user data. The worst known case was Chat & Ask AI by Codeway. Researchers say it exposed chat histories, phone numbers and email addresses tied to millions of users. Another app, YPT – Study Group, reportedly leaked messages, user IDs and access tokens. CovertLabs tracks these incidents in a restricted repository called Firehound. The full list of affected apps has not been publicly released, and researchers say the data is limited to prevent further exposure and to give developers time to fix security flaws.

Why Apple’s App review can miss hidden security risks

Apple reviews apps before they appear in the App Store. However, the review process does not scan app code for hidden secrets. If an app behaves normally during testing, it can pass review even if sensitive keys are buried inside its files. This creates a gap between Apple’s security claims and real-world risks. Removing leaked secrets is not simple for developers. They must revoke old keys, create new ones and rebuild parts of their apps. That can break features and delay updates. Even though Apple says most app updates are reviewed within 24 hours, some updates take weeks. During that time, vulnerable apps can remain available.

CyberGuy contacted Apple for comment, but did not receive a response before publication.

Ways to stay safe right now

You cannot easily inspect an app for hidden secrets. Apple does not provide tools for that. Still, you can reduce your risk and limit exposure by being selective and cautious. These steps help reduce the risk if an app leaks data behind the scenes.

1) Stick to established app developers

Well-known developers tend to have stronger security teams and better update practices. Smaller or unknown apps may rush features to market and overlook security basics. Before downloading, check how long the developer has been active and how often the app is updated.

2) Review and limit app permissions

Many apps ask for more access than they need. Location, contacts, photos and microphone access all increase the risk of data leaks. Go into your iPhone settings and remove permissions that are not essential for the app to work.

3) Delete apps you no longer use

Unused apps still retain access to data you shared in the past. They may also store information on remote servers long after you stop opening them. If you have not used an app in months, remove it. Here’s how: Open Settings, tap General, select iPhone Storage, and scroll through the list of apps to see when each one was last used. Tap any app you no longer need and select Delete App to remove it and reduce ongoing data exposure.

4) Be cautious with personal and financial details

Avoid entering sensitive information unless it is absolutely necessary. This includes full names, addresses, payment details and private conversations. AI apps are especially risky if you share deeply personal content.

5) Use a password manager for every account

A password manager creates strong, unique passwords for each app and service. This prevents attackers from accessing multiple accounts if one app leaks data. Never reuse passwords tied to your email address.

Next, see if your email has been exposed in past breaches. Our No. 1 password manager pick includes a built-in breach scanner that checks whether your email address or passwords have appeared in known leaks. If you discover a match, immediately change any reused passwords and secure those accounts with new, unique credentials.

Check out the best expert-reviewed password managers of 2026 at Cyberguy.com.

6) Change passwords tied to exposed apps

If an app uses your email address for login, change that password immediately. Do this even if there is no confirmation of a breach. Attackers often test leaked credentials across other services.

7) Consider using a data removal service

Some leaked data ends up with data brokers that sell personal information online. A data removal service can help find and remove your details from these databases. This reduces the chance that exposed app data gets reused for scams or identity theft.

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.

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.

8) Monitor your accounts for unusual activity

Watch for unexpected emails, password reset notices, login alerts, or payment confirmations. These can signal that leaked data is already being abused. Act quickly if something looks off.

9) Pause use of risky AI and chat apps

If you use AI apps for private conversations, consider stopping until the developer confirms security fixes. Once data is exposed, it cannot be pulled back. Avoid sharing sensitive details with apps that store conversations remotely.

Kurt’s key takeaways

Apple’s App Store still offers important protections, but this research shows it is not foolproof. Many trusted iPhone apps quietly expose data due to basic security mistakes. Until app reviews improve, you need to stay alert and limit how much data you share.

Dyson’s powerful 360 Vis Nav robovac is down to $279.99 for a limited time

Dyson’s powerful 360 Vis Nav robovac is down to 9.99 for a limited time

If you’re tired of running your vacuum multiple times just to get the dirt and debris out of the carpets in your living room, Dyson’s 360 Vis Nav is worth a look. It’s one of the more powerful robot vacuums currently available, and now through May 11th (or while supplies last), it’s on sale at Woot for an all-time low of $279.99 ($919 off) with a full two-year warranty.

The last-gen 360 Vis Nav offers a whopping 65 air watts of suction, allowing it to pull dirt, dust, and pet hair from carpets impressively well. In her brief time testing the robovac, my colleague Jennifer Pattison Tuohy said the Dyson “demolished a pile of dry oatmeal in seconds,” adding that she briefly worried it might even suck up the tassels on her large rug (it didn’t). By comparison, many robot vacuums — including Dyson’s new $1,200 Spot + Scrub AI — require multiple passes to fully eradicate the same kind of mess on your floor.

What’s more, the robovac’s small, D-shaped design and the location of its ultra-fluffy brush allow it to dig into edges and corners more effectively than many of the more roundish robot vacuums, while its lower profile lets it easily get under most beds and sofas. The roomy 500ml dustbin also means you likely won’t need to empty it too often, while Dyson’s built-in handle and terrific quick-release button make removing said bin a relatively simple task when it’s time to do so.

While it is undeniably powerful, it’s worth noting that the 360 Vis Nav lacks a few features found on some of its more modern rivals. Although its navigation worked well enough during our testing, it lacks AI-powered obstacle avoidance and doesn’t come with a self-emptying dock. Battery life is also relatively short at around 65 minutes per charge. Nonetheless, if your top priority is quickly removing dust, dirt, and pet hair from carpets without multiple passes, the Dyson remains an option worth considering, especially at this discounted price.

Global scam crackdown leads to 276 arrests

NEWYou can now listen to Fox News articles!

We’ve often warned you about romance scams and crypto “investment” opportunities that feel too good to pass up. Now, there’s a major update that shows just how organized these operations have become.

The Department of Justice and Federal Bureau of Investigation announced a sweeping international operation that led to at least 276 arrests and the shutdown of multiple scam centers tied to cryptocurrency fraud. These networks targeted Americans and drained millions of dollars from victims.

The operation spanned continents and involved coordinated efforts by law enforcement and tech companies.

TOP 5 SCAMS SPREADING RIGHT NOW

How the cryptocurrency scam crackdown unfolded

Authorities worked with partners around the world, including the Dubai Police and law enforcement agencies in Thailand and beyond. Together, they dismantled at least nine scam centers linked to large-scale crypto fraud.

Several suspects now face federal charges in the United States, including wire fraud and money laundering. Investigators say these operations functioned like businesses, with recruitment, management layers and structured systems designed to deceive victims.

Officials made it clear that this effort sends a message. Fraud crosses borders, and enforcement is now doing the same.

How crypto investment scams target victims

These schemes often follow a pattern known as “pig-butchering.” It is a slow, calculated tactic that builds trust before any money is involved.

A scammer may reach out through social media or a messaging app and start a casual conversation. Over time, that interaction turns more personal. In some cases, it feels like a real relationship. Once trust is established, the topic shifts toward investing, often framed as a unique crypto opportunity.

Victims are guided through setting up accounts and transferring funds to platforms that appear legitimate. The dashboards may even show fake gains to build confidence. At that point, control of the money is already gone. Funds are quickly moved through multiple accounts and eventually end up with the scammers.

Many victims are encouraged to keep going, sometimes borrowing money or taking out loans to invest more. By the time the truth becomes clear, the losses can be devastating.

How Meta Platforms, Inc. helped track scam networks

Meta Platforms, Inc. played a key role in the investigation by providing data that helped law enforcement identify and track these networks.

The company says it has taken aggressive action across its platforms. In 2025 alone, Meta removed more than 159 million scam ads and shut down 10.9 million accounts linked to scam centers. More recently, it disabled over 150,000 accounts connected to these networks as part of a coordinated enforcement effort.

“Meta is committed to combatting online fraud and scams, and we are proud to partner with law enforcement in these efforts,” Chris Sonderby, Meta’s vice president and deputy general counsel, said. “We applaud the DOJ and FBI for their leadership in holding criminal scammers accountable and protecting American consumers.”

New tools to stop cryptocurrency scams in real time

Meta is also rolling out new protections across its apps to help users spot scams before they get pulled in.

On Facebook, users may see alerts tied to suspicious friend requests, especially when an account shows unusual behavior such as limited connections or inconsistent location details.

On WhatsApp, new warnings are designed to prevent scammers from linking their own devices to someone else’s account, giving users a chance to pause before approving a risky request.

Messenger is also expanding its scam detection tools. When a conversation shows patterns linked to common fraud tactics, users may receive prompts that explain the risk and suggest actions like blocking or reporting the account.

Why this cryptocurrency scam crackdown matters to you

This operation highlights how organized these scam networks have become. These are not random messages from a single person. They are coordinated groups running structured operations designed to build trust, create urgency and move money quickly.

Even with hundreds of arrests, the threat remains. New networks continue to emerge, often using the same playbook with slight changes. That means staying informed is still one of the most effective ways to protect yourself. 

Ways to stay safe from cryptocurrency scams

Scammers follow familiar patterns, which means there are clear warning signs you can watch for and simple steps you can take to protect yourself.

1) Slow down unexpected connections

If someone you do not know reaches out and quickly builds a personal connection, slow things down and question the situation. Scammers rely on momentum, so taking a pause can help you spot inconsistencies. 

2) Verify investment platforms before sending money

Before sending money to any investment platform, take time to verify that it is legitimate. A professional-looking website or app does not guarantee it is real. Look for independent reviews and official registration details.

3) Avoid sending crypto to unknown sources

Avoid sending cryptocurrency to individuals or platforms you cannot confirm. Once those transactions go through, they are extremely difficult to recover.

4) Watch for pressure and urgency

Be aware of pressure. If someone pushes you to act quickly or invest more, that urgency is often a warning sign.

5) Use strong antivirus protection

Strong antivirus software can help block malicious links, fake investment sites and other threats before they reach you, adding another layer of defense against scam attempts.

6) Limit your personal data exposure

Scammers often rely on publicly available information to build trust. Reducing how much of your personal data appears online by using a data removal service can make it harder for them to target you in the first place. 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.

7) Strengthen your account security

It also helps to strengthen your digital security. Enable two-factor authentication (2FA) on your accounts and use trusted security tools to reduce exposure to malicious links and messages.

8) Report scams as soon as possible

If you believe you have been targeted or defrauded, report it to the FBI’s Internet Crime Complaint Center at ic3.gov as soon as possible.

Kurt’s key takeaways

This global crackdown is a meaningful step forward. It shows what can happen when law enforcement, tech companies and international partners work together. At the same time, these scams are not going away. The tactics will continue to evolve, and new networks will take the place of those that were shut down. Awareness and caution remain your strongest defenses.

Asus chases Elgato with its own secondary touchscreen display

Asus chases Elgato with its own secondary touchscreen display

Asus’s latest gaming monitor is a little smaller than usual. The ROG Strix XG129C, announced on Friday, is a 12.3-inch touchscreen IPS display that’s intended to be a sidekick for a larger main monitor, similar to the 14.1-inch secondary display in the 2020 Asus ROG Zephyrus Duo 15. It’s a slightly smaller competitor to Corsair’s Xeneon Edge, which has a 14.5-inch display, but the same 720p resolution.

Asus says the XG129C covers 125 percent of the sRGB color gamut and 90 percent of the DCI-P3 color gamut. It also comes with a one-year subscription for the hardware monitoring tool AIDA64 Extreme, which would usually cost $65. Besides acting as a performance monitor for your PC, sidekick displays like this can also be handy as an extension for streaming or editing setups, much like Elgato’s Stream Deck.

Along with the little XG129C, Asus also announced the ROG Strix OLED XG34WCDMS, a 34-inch RGB Tandem QD-OLED gaming monitor. It features a 280Hz refresh rate and a 3440 x 1440p resolution, and, according to Asus, covers 99 percent of the DCI-P3 color gamut. Asus has not yet officially announced pricing for either display.
