Smart home device maker exposes 2.7 billion records in huge data breach

Data breaches keep happening, and too often they come down to companies failing to take cybersecurity seriously. Some of the biggest breaches have been caused by negligence, and now there’s another major one to add to the list. Mars Hydro, a Chinese company that makes Internet of Things (IoT) devices like LED lights and hydroponics equipment, left a massive database unprotected online. As a result, 2.7 billion records were exposed to anyone who knew where to look.

What happened?

Mars Hydro, a Chinese manufacturer of IoT devices, suffered a massive data breach after a publicly accessible, unprotected database containing nearly 2.7 billion records was discovered online. The 1.17-terabyte database was not password-protected or encrypted, exposing a massive amount of sensitive information related to the company’s smart devices, including LED grow lights and hydroponic equipment.

The database contained logging, monitoring and error records for IoT devices sold worldwide. Among the exposed data were Wi-Fi network names (SSIDs), Wi-Fi passwords, IP addresses, device ID numbers and other details linked to user devices and the Mars Pro IoT software application. Plus, internal records referenced LG-LED SOLUTIONS LIMITED, a California-registered company, as well as Spider Farmer, which produces agricultural equipment.

Security researcher Jeremiah Fowler identified the database and immediately sent a responsible disclosure notice to LG-LED SOLUTIONS and Mars Hydro. Within hours, public access to the database was restricted.

It remains unclear how long the database was publicly accessible or whether any unauthorized parties accessed the data before its restriction. The only way to confirm potential access or misuse would be through an internal forensic audit, but no such investigation has been publicly disclosed.

THE HIDDEN COSTS OF FREE APPS: YOUR PERSONAL INFORMATION

Should you be worried?

The unprotected database contained highly sensitive user and device information, including SSIDs and passwords stored in plain text, which could allow unauthorized users to access home networks. Although the researcher did not indicate that any personally identifiable information was exposed, the presence of network credentials, IP addresses, device ID numbers and data about smartphones running the IoT software raises serious security concerns.

The exposed credentials could theoretically enable an attacker to connect to the network, compromise other devices, intercept data or even launch targeted cyberattacks. This risk is particularly troubling, given the broader vulnerabilities within the IoT industry. 

According to a threat report by Palo Alto Networks, 57% of IoT devices across all industries are considered highly vulnerable, and an alarming 98% of data transmitted by these devices is unencrypted. The report further found that 83% of connected devices operate on outdated or unsupported operating systems, leaving them susceptible to attacks that exploit known vulnerabilities.

This incident underscores a recurring problem in the IoT sector: poor security practices, weak data protection and the absence of encryption. Without proactive security measures, such breaches will likely continue, exposing users to risks that extend beyond just their IoT devices, potentially compromising entire home or business networks.

6 ways you can protect yourself

If you own a Mars Hydro device or use the Mars Pro app, take the following steps to protect your data and secure your network:

1) Change your Wi-Fi password: Since Wi-Fi network names and passwords were stored in plain text, the first step is to update your router password immediately. Even if you believe your credentials were not directly exposed, it’s best to assume otherwise. A strong password should be complex, combining upper and lowercase letters, numbers and special characters. Avoid using simple or easily guessable passwords, such as your name, address or basic numerical sequences.

2) Enable two-factor authentication (2FA): If your router supports two-factor authentication, enabling it adds an extra layer of security. This ensures that even if someone gains access to your login credentials, they would still need a secondary authentication code – typically sent via text message or an authentication app – to log in. This significantly reduces the risk of unauthorized access.

3) Monitor your network for unusual activity: With Wi-Fi credentials and IP addresses exposed, attackers could attempt to access your network remotely. Checking your router’s admin panel regularly to review connected devices is an important security measure. If you notice an unfamiliar device, remove it immediately and change your Wi-Fi password again.

4) Keep your devices updated: IoT devices are notorious for running outdated or unsupported software, making them vulnerable to cyberattacks. Regularly updating the firmware and software of your smart devices ensures that you receive the latest security patches. Check your device settings for available updates and install them as soon as they are released. Keeping your router’s firmware updated is equally important, as routers are a primary target for hackers.

5) Beware of phishing attempts and use strong antivirus software: Hackers may try to exploit the data from this breach by launching phishing attacks. If you receive an email claiming to be from Mars Hydro or LG-LED SOLUTIONS, urging you to reset your password or provide personal details, be cautious. Cybercriminals often create fake login pages designed to steal credentials. Do not click on suspicious links or download attachments from unknown senders.

The best way to safeguard yourself from malicious links is to have antivirus software installed on all your devices. This protection can also alert you to phishing emails and ransomware scams, keeping your personal information and digital assets safe. Get my picks for the best 2025 antivirus protection winners for your Windows, Mac, Android and iOS devices.

6) Remove your exposed data from data brokers: With 2.7 billion records exposed, your personal and network information may already be circulating among data brokers – companies that collect and sell user data, often without consent. Hackers and scammers use these databases to launch phishing attacks, identity theft scams and targeted cyber intrusions. Check out my top picks for data removal services here.

MASSIVE SECURITY FLAW PUTS MOST POPULAR BROWSERS AT RISK ON MAC

Kurt’s key takeaway

The Mars Hydro breach is yet another reminder of the security risks that come with IoT devices. Companies need to do a better job of protecting user data, but at the end of the day, it is up to you to secure your own network. Updating passwords, enabling two-factor authentication and keeping an eye on your connected devices can make a big difference in keeping your data safe and your smart home secure.

Apple starts testing end-to-end encrypted RCS messages on iPhone

Apple starts testing end-to-end encrypted RCS messages on iPhone

Apple is starting to test end-to-end encrypted (E2EE) RCS messages with the developer beta of iOS 26.4 released Monday. Apple announced plans last year to support the feature, and once fully available, it will let iPhone and Android users send encrypted RCS messages to each other across platforms.

However, with this initial implementation, Apple is only testing RCS encryption between Apple devices. It’s “not yet testable with other platforms,” Apple says. The company also doesn’t plan to ship E2EE RCS messages with iOS 26.4; the feature will actually ship publicly in a “future update,” Apple says.

RCS messages significantly improve the experience of texting between iPhone and Android devices, but cross-platform encryption has been a big thing missing. The GSM Association, which helps develop RCS, announced in September 2024 that it was working on E2EE messages as part of the “next major milestone” for the RCS Universal Profile, and Apple said in March 2025 that it would support E2EE RCS messages on iOS, iPadOS, macOS, and watchOS in “future software updates.”

Wearable robotics are changing how we walk and run

NEWYou can now listen to Fox News articles!

When you hear the word robotics, you probably think of factory machines or humanoid robots sprinting across a test track. That image makes sense. For years, robotics lived in labs and industrial spaces. 

But a quieter shift is happening much closer to home. It is happening around your ankles, knees and hips. Wearable robotics are moving out of research labs and into everyday life. From powered shoes to lightweight exoskeletons, this new wave of assisted movement technology is becoming a real consumer category. 

The goal is not to replace your effort. It is to support it. And that shift is bigger than any single brand.

AI WEARABLE HELPS STROKE SURVIVORS SPEAK AGAIN

From elite athletes to everyday use: the shift in wearable robotics

For years, sports innovation focused on speed. Lighter foam. Carbon plates. Better traction. Most of those gains targeted elite competitors. Now the focus is expanding beyond race day. Nike’s Project Amplify, developed with robotics partner Dephy, is one example. The system pairs a carbon plate inside the shoe with a motorized cuff worn above the ankle. Sensors track stride patterns in real time, and the cuff provides subtle forward assistance designed to feel smooth and natural. Instead of forcing movement, it learns it.

Earlier attempts at powered footwear struggled because batteries and motors were too heavy to sit inside a shoe. The result felt awkward and unbalanced. Modern designs solve that problem by moving energy storage above the ankle or to the hips. By shifting weight higher on the leg, engineers reduce strain on the foot and improve balance.

Battery improvements and smarter motion sensors also play a role. Today’s systems adapt to your stride in real time, making assisted movement feel less like equipment and more like an extension of your body. The company has said it is targeting a commercial release around 2028.  But Nike is not alone in this space.

Powered footwear and exoskeletons are entering the consumer market

If you have ever felt your legs get heavy halfway through a long walk, you understand why this category exists. Maybe it is a trip through the airport, a walk around the neighborhood or a few flights of stairs that feel steeper than they used to. Most people are not trying to run faster. They just want to move without feeling worn out. That is where wearable robotics are starting to show up. Companies are building products meant for real people, not just elite athletes or lab testing.

Early consumer exoskeletons for outdoor movement

The Hypershell X is one example. It is a lightweight outdoor exoskeleton designed for hikers and long-distance walkers. The system wraps around the waist and legs and uses small motors to reduce fatigue on climbs and uneven terrain. The goal is straightforward. Help you go farther without feeling drained halfway through the trail. Hypershell also introduced the X Ultra, a more powerful version built for steeper terrain and longer outings. It delivers stronger assist levels while staying compact enough to wear under standard outdoor gear. Both models are designed for recreational users who want endurance support, not medical treatment.

Dnsys has also introduced the X1 all-terrain exoskeleton. The hip-mounted system is marketed to hikers and outdoor enthusiasts who want help reducing fatigue on climbs and long treks. Unlike lab prototypes, the X1 has been sold through crowdfunding and direct online orders, making it one of the early consumer entries in this space.

Wearable robotics designed for everyday walking

Another example is WIM from WIRobotics. This wearable robot weighs about 3.5 pounds and supports natural hip movement while walking. It is meant for older adults, active adults and people recovering from minor injuries who want extra assistance without wearing something bulky or clinical looking.

From medical exoskeletons to consumer devices

The medical side of wearable robotics has been evolving even longer. Companies like Ekso Bionics and ReWalk have developed powered exoskeletons that help people with spinal cord injuries or stroke stand and walk. These systems are used in rehabilitation clinics and in select personal mobility programs. They show how wearable robotics first proved themselves in medical settings before gradually influencing consumer designs.

These products vary in power, price and purpose. What connects them is a shared direction. Wearable robotics are beginning to actively assist movement, not just track it.

How wearable robotics help reduce fatigue and movement hesitation

Here is something people rarely admit. It is not always an injury that stops movement. It is hesitation. Many people worry about knee pain creeping in halfway through a walk. Others fear running out of energy before they make it home. Some quietly stress about slowing everyone else down.

Those doubts shorten walks and cancel runs long before physical limits do. Wearable robotics hopes to close that confidence gap. By reducing fatigue and supporting joints, assisted movement systems can make activity feel realistic again for people who might otherwise skip it. Effort does not disappear. The barrier to starting simply becomes lower.

Powered footwear and wearable robotics support natural movement

A better comparison might be e-bikes. Electric assistance did not eliminate cycling. Instead, it expanded who felt comfortable getting on a bike in the first place. Powered footwear and wearable robotics could have a similar effect on walking and running. In practical terms, that might look different for different people.

Some commuters could replace short car trips. Older adults might stay active longer without feeling as worn out. Casual runners could finish a workout with energy to spare instead of dragging through the final mile. In other words, this shift is not about creating super athletes. It is about widening the circle of people who feel capable of participating.

What this means to you

You may never strap on a powered exoskeleton. You may not be waiting for motorized shoes to hit stores in 2028. But this shift still matters. If walking a long trail leaves your knees aching, or if you skip runs because you worry about burning out halfway through, this kind of technology is being built with you in mind. The goal is not to turn anyone into a super athlete. It is to make movement feel more doable.

For some people, that could mean walking an extra mile without thinking twice. For others, it might mean keeping up with friends, staying active longer or feeling a little less hesitant about getting started. Wearable robotics are changing the conversation. Instead of asking how fast you can go, the question becomes simpler. How comfortable do you want to feel while moving? And that is a very different way to think about fitness.

Kurt’s key takeaways

Wearable robotics systems are still in the early stages of consumer adoption. Most powered footwear and exoskeleton systems remain expensive and limited in availability. But the direction is clear. Technology is shifting from tracking your performance to actively supporting it. That is a meaningful change. If assisted movement becomes as common as smartwatches or fitness trackers, it could reshape how people think about aging, endurance and daily mobility. Walking farther may feel realistic again. Running may feel less intimidating. Staying active later in life could become more achievable for millions. The real question is not whether wearable robotics will improve. They will. The bigger question is how we choose to use them.

If wearable robotics can help you walk and run with less strain, would you try them, or would you rather rely only on your own effort? Let us know by writing to us at Cyberguy.com.

Samsung ad confirms rumors of a useful S26 ‘privacy display’

Samsung ad confirms rumors of a useful S26 ‘privacy display’

Samsung has released a new advertisement for its upcoming Galaxy S26 launch that all-but confirms rumors of a new display with a built-in privacy mode. Leaked videos show that the feature could be capable of entirely blacking out content from specific apps or parts of the display when viewed at an angle.

The new advert shows a woman reading a racy romance novel on a subway, while curious passengers look over her shoulder. An overlay shows a quick flick of a “Zero-peeking privacy” toggle, which blacks out the titillating content for the nosy onlookers.

That might sound similar to existing privacy filters, which have been available as after-market screen protectors for years, or found built into products including certain HP laptops. But leaks say what Samsung has in store for the S26 range is different.

It will reportedly use a new type of OLED panel that Samsung Display first debuted two years ago at MWC 2024 called Flex Magic Pixel. It allows viewing angles to be adjusted on a pixel-by-pixel basis, so the privacy effect is only applied to certain parts of the screen at a time. Combined with some AI, that means it could automatically protect sensitive information in a banking app, or be used to hide notifications in a messaging app, as shown in this short video clip shared by the reliable leaker Ice Universe.

We’ll find out more soon enough — Samsung has confirmed that its Unpacked launch event will take place later this month, on February 25th.
