Half a million patients' personal info stolen in massive health care data breach
Data breaches happen all the time, and while no data breach should be ignored, those involving health care institutions require special attention.
These breaches can be very damaging and haunt people for life. Recently, hackers leaked the personal data of around 500,000 Americans.
They breached the databases of the Center for Vein Restoration (CVR), which claims to be “America’s largest physician-led vein center,” stealing not just personal data but also medical records.

What you need to know
CVR, a clinic headquartered in Maryland, experienced a massive data breach where hackers stole highly sensitive personal information, including lab results and health insurance details, as reported by Cybernews. The breach occurred in early October, with the clinic detecting “unusual activity” in its systems on Oct. 6.
CVR has more than 110 branches across the country, from Alabama to Alaska. This breach has affected hundreds of thousands of individuals. According to a notice filed by CVR with the U.S. Department of Health and Human Services Office for Civil Rights, more than 445,000 people had their personal information compromised.
As the name suggests, CVR specializes in vein restoration, a very specialized procedure aimed at improving the health and function of veins. This means the clinic keeps a very elaborate record of its patients’ health, and now all that is in the hands of hackers, along with copious amounts of personal information.
The full list of exposed data includes addresses, dates of birth, Social Security numbers, driver’s license numbers, medical record numbers, diagnoses, lab results, medications, treatment information, health insurance information, provider names, dates of treatment and financial information.

The risks associated with the CVR data breach
The risks of data breaches depend on the type of company affected. For instance, breaches involving companies like Ticketmaster are generally more manageable because they often expose information like contact details, addresses and, in some cases, identification documents. Even if financial data is leaked, it can typically be mitigated by replacing or blocking compromised accounts.
Health care data breaches, however, are far more severe. When companies like CVR are targeted, hackers gain access to sensitive medical records that cannot be altered. Your medical history is permanent and highly sought after on the dark web. Cybercriminals can use this information to commit identity fraud, such as obtaining prescription drugs through false insurance claims. Plus, detailed knowledge of medical treatments, lab results and medications allows attackers to create highly targeted phishing scams, exploiting victims’ vulnerabilities with alarming precision.

7 ways to keep yourself safe from such data breaches
1. Regularly monitor your financial and medical accounts: Periodically review your medical records and health insurance statements for any unusual or unauthorized activity. This can help you quickly identify and address any discrepancies or fraudulent activities.
Use patient portals provided by health care providers to access your medical records online. These portals often have features that allow you to track your medical history and appointments.
2. Use strong passwords and two-factor authentication: Create strong, unique passwords for your online accounts, including health care portals. Avoid using easily guessable information like birthdays or common words. Consider using a password manager to generate and store complex passwords.
3. Enable two-factor authentication (2FA) wherever possible: 2FA adds an extra layer of security by requiring a second form of verification, such as a text message code or authentication app, in addition to your password.
4. Don’t fall for phishing scams; use strong antivirus software: Be mindful of the information you share online and with whom you share it. Avoid providing sensitive personal information, such as Social Security numbers or medical details, unless absolutely necessary. Verify the legitimacy of any requests for personal information. Scammers often pose as health care providers or insurance companies to trick you into revealing sensitive data by asking you to click on links in emails or messages.
The best way to safeguard yourself from malicious links that install malware, potentially accessing your private information, 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 2024 antivirus protection winners for your Windows, Mac, Android and iOS devices.
5. Use identity theft protection services: Consider enrolling in identity theft protection services that monitor your personal information and alert you to potential threats. These services can help you detect and respond to identity theft more quickly. Some identity theft protection services also offer insurance and assistance with recovering from identity theft, providing additional peace of mind. See my tips and best picks on how to protect yourself from identity theft.
6. Freeze your credit: A credit freeze prevents anyone from opening new credit accounts in your name without your authorization, reducing the risk of identity theft. Contact the major credit bureaus (Experian, Equifax and TransUnion) to request a credit freeze. This is often free and can be temporarily lifted when you need to apply for credit.
7. Remove your personal data from the internet: After being part of a data breach, it’s crucial to minimize your online presence to reduce the risk of future scams. Consider using a personal data removal service that can help you delete your information from various websites and data brokers. This can greatly diminish the chances of your data being used maliciously. Check out my top picks for data removal services here.

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.
10 HEALTH TECH PRODUCTS STEALING THE SPOTLIGHT AT CES 2026

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 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.
