Windows 10 security flaws leave millions vulnerable
Windows 11 is the latest and greatest operating system from Microsoft, but it has its flaws, so much so that even four years after its release, some people are sticking with older versions. Windows 10 remains the operating system of choice for many, even though Microsoft has shifted its focus entirely to Windows 11. In fact, the Redmond-based company will end security updates for Windows 10 this October.
If that’s not enough to push you toward upgrading, the latest news might be. The 240 million Windows 10 users are vulnerable to dozens of security vulnerabilities, six of which are reportedly already being exploited by bad actors.

Critical Windows 10 security flaws exploited
The vulnerabilities in question were part of a recent Microsoft Patch Tuesday update, a monthly release where the company addresses security flaws. In this case, six specific exploits were identified as being actively used by hackers to target Windows 10 systems. These exploits are particularly alarming because they are already in the wild, meaning attackers are leveraging them to compromise systems before all users have had a chance to update their devices.
The affected population, estimated at 240 million, refers to users whose PCs cannot upgrade to Windows 11 due to hardware limitations, such as lacking TPM 2.0 (Trusted Platform Module) or other system requirements.
The six exploits include a mix of flaws that allow hackers to achieve various malicious outcomes, such as executing arbitrary code, escalating privileges to take full control of a system or bypassing security features.
For example, one exploit might overload system memory to overwrite critical data (a buffer overflow), while another could allow attackers to access sensitive information by exploiting a flaw in the Windows Kernel. These vulnerabilities are especially dangerous because they can be triggered remotely or through seemingly innocuous actions, like opening a malicious file or mounting a compromised virtual hard disk.

CLICKFIX MALWARE TRICKS YOU INTO INFECTING YOUR OWN WINDOWS PC
A fix is there (for now)
Microsoft has released patches to address these issues, and America’s Cyber Defense Agency has urged users to update their systems immediately, ideally by this month, or risk severe consequences. The agency even suggested turning off unpatched computers as a precaution. Updating to the latest Windows 10 patch is the simplest and most effective way to protect against these exploits right now.
However, a bigger problem looms later this year. Microsoft will officially end free security updates for Windows 10 on October 14, 2025. After that, systems running Windows 10 will no longer receive critical security patches, unless users enroll in Microsoft’s Extended Security Updates (ESU) program.
This ESU program will be available to individual users for the first time and will cost $30 per device for one additional year of updates. It’s designed to give users more time to transition, especially those who can’t upgrade to Windows 11 due to hardware limitations. While this offers a temporary reprieve, it’s not a long-term solution; the ESU program will only extend support for a limited time (typically three years in enterprise settings) and prices may increase annually.
The scale of the problem remains significant. Millions of devices lack the hardware requirements for Windows 11, such as TPM 2.0 and newer CPUs, making the shift costly or impractical for some. Analysts warn this could contribute to a surge in electronic waste, unless recycling and repurposing efforts improve dramatically.

MICROSOFT SETS MAY END DATE FOR SKYPE AFTER 14-YEAR RUN
3 additional ways to stay safe from Windows vulnerabilities
1) Use strong antivirus software: Even with the latest patches, no system is entirely immune to threats. Strong antivirus software can act as a second line of defense, detecting and neutralizing malware that exploits vulnerabilities before they cause harm. Look for solutions with real-time protection and frequent updates to tackle emerging threats. While this won’t fix unpatched system flaws after October 2025, it can reduce risks from common attack vectors like phishing or malicious downloads. Get my picks for the best 2025 antivirus protection winners for your Windows, Mac, Android and iOS devices.
2) Limit exposure: Many exploits rely on user interaction, such as clicking a shady link, downloading a compromised file or mounting an untrusted virtual disk. Stick to reputable websites, avoid opening unsolicited email attachments and use a browser with built-in security features (like Microsoft Edge or Chrome with Safe Browsing enabled).
3) Plan for the future: The clock is ticking on Windows 10’s security updates. If your hardware can’t handle Windows 11, weigh your long-term options. Buying a new PC might be inevitable, but you could also explore alternatives like Linux, which offers free, secure operating systems (e.g., Ubuntu or Linux Mint) that run well on older hardware.
Kurt’s key takeaway
The road ahead for Windows 10 users is anything but smooth. With critical vulnerabilities emerging and official support coming to an end, millions are being pushed into a difficult decision. They can upgrade their hardware, pay for temporary patches or continue using increasingly vulnerable systems. As October draws closer, the risks will only increase. Updating your system is essential, but it’s just a short-term measure. Now is the time to start preparing for what comes after, before the window of protection closes for good.

Sony’s XM5 headphones and the latest Kindle round out this week’s best deals
If you’re feeling the stress of having procrastinated on your holiday shopping — and you missed out during Black Friday and Cyber Monday — we’ve got you. We’ve found a variety of gadgets on sale that make for great gifts, many of which will ship in time for the holidays. One of the standouts is the current promo on Sony’s noise-canceling WH-1000XM5 headphones, which are on sale with a free pair of wireless earbuds. Other deals you may have missed include steep discounts on Amazon’s latest entry-level Kindle and the new Echo Dot Max.
Sony’s last-gen WH-1000XM5 have consistently impressed us with their audio quality, active noise cancellation, and comfort. And right now, Amazon is offering them with a free pair of Sony’s WF-C700N earbuds for $248 ($152 off). The headphones have an updated design that includes a thinner headband, more memory foam in the ear pads, and repositioned mics that reduce wind noise when taking calls. These changes didn’t add much weight, and the headphones still get 30 hours of playtime with ANC enabled.
The XM5 sounded “more refined, detailed, and spacious” in our tests, but we noticed less oomph when listening to EDM or hip-hop tracks with a lot of bass. The headphones have eight microphones, four of which are for voice, and their excellent noise reduction on calls was immediately noticeable, even in louder environments. The $89.99 WF-C700N, meanwhile, are a midrange pair of noise-canceling earbuds with an IPX4 rating, up to seven and a half hours of battery life (with ANC enabled), and a slim design.
Amazon’s 11th-gen Kindle is our favorite budget-friendly e-reader, and you can pick up the ad-supported version for $89.99 ($20 off) at Amazon, Best Buy, and Target. The entry-level ebook reader features a six-inch 300ppi E Ink display that won’t show glare from the sun like your phone or tablet. It has enough storage space to hold thousands of books, or dozens of audiobooks from Audible, the latter of which you can play via Bluetooth headphones or speakers.
The Kindle’s built-in battery lasts up to six weeks, depending on how long you read per day and how reliant you are on its backlight, and recharges over USB-C. It has the same screen resolution and storage as the step-up Kindle Paperwhite, but it’s not waterproof, which may matter if you like to read at the beach or in the bath.
Amazon’s last-minute “Super Saturday” sale is underway, though, we’d argue some of the better deals are actually some the lingering discounts we’re seeing on Amazon’s own devices, many of which have been effect for several weeks. Right now, for instance, you can grab the new Echo Dot Max at Amazon, Best Buy, and Target for $79.99 ($20 off), which is the best price we’ve seen on the smart speaker since it launched.
Despite the name, the Dot Max is less of a follow up to the Echo Dot as it is the fourth-gen Echo from 2020. It’s got a compact knit fabric design, simpler controls, a better processor, and more smart home sensors and radios than prior models (it offers support for Matter, Thread, and Zigbee protocols). It still sounds great for its size, though, and like prior models, it can function as an Wi-Fi extender if you’re looking buoy a Eero mesh network. It’s also one of the first devices to offer Amazon’s AI-powered Alexa Plus out of the box, which, while still very much a work in progress, is a step in the right direction.

Data breach exposes 400,000 bank customers’ info
NEWYou can now listen to Fox News articles!
A major data breach tied to U.S. fintech firm Marquis is rippling through banks, credit unions and their customers. Hackers broke into Marquis systems by exploiting a known but unpatched vulnerability in a SonicWall firewall, gaining access to deeply sensitive consumer data.
At least 400,000 people are confirmed to be affected so far across multiple states. Texas has been hit the hardest with more than 354,000 residents affected. That number is expected to rise as additional breach notifications are filed.
Marquis operates as a marketing and compliance provider for financial institutions. The company says it serves more than 700 banks and credit unions nationwide. That role gives Marquis access to centralized pools of customer data, which also makes it a high-value target.

What information was stolen in the Marquis cyberattack
According to legally required disclosures filed in Texas, Maine, Iowa, Massachusetts and New Hampshire, hackers accessed a wide range of personal and financial data. Stolen information includes customer names, dates of birth, postal addresses, Social Security numbers and bank account, debit and credit card numbers. The breach dates back to Aug. 14, when attackers gained access through the SonicWall firewall vulnerability. Marquis later confirmed the incident was a ransomware attack.
While Marquis did not publicly name the attackers, the campaign has been widely linked to the Akira ransomware gang. Akira has previously targeted organizations running SonicWall appliances during large-scale exploitation waves. This was not a routine credential leak.
We reached out to Marquis for comment, and a company spokesperson provided CyberGuy with the following statement:
“In August, Marquis Marketing Services experienced a data security incident. Upon discovery, we immediately enacted our response protocols and proactively took the affected systems offline to protect our data and our customers’ information. We engaged leading third-party cybersecurity experts to conduct a comprehensive investigation and notified law enforcement.
“The incident was quickly contained, and our investigation was recently completed. It was determined that an unauthorized third party accessed certain non-public information within our network. However, there is no evidence indicating that any personal information has been used for identity theft or financial fraud. We have notified potentially affected individuals.
“We know our customers place great trust in us, and at Marquis, we take that responsibility seriously by making the protection of their information our highest priority. We are extremely appreciative of the cooperation, understanding, and support of our employees and customers during this time.”
HOW TO STOP IMPOSTOR BANK SCAMS BEFORE THEY DRAIN YOUR WALLET
Why the Marquis data breach creates long-term identity risk
When a data breach exposes your full identity, the danger does not disappear after the news cycle ends. Unlike a stolen password, this kind of information cannot be changed, which means the risk can stick around for a long time.
“With a typical credential leak, you reset passwords, rotate tokens and move on,” Ricardo Amper, CEO and Founder of Incode Technologies, a digital identity verification company, tells CyberGuy. “But core identity data is static. You cannot meaningfully change your date of birth or SSN, and once those are exposed, they can circulate on criminal markets for years. The breach is a moment in time, but the exposure it creates can follow people for the rest of their financial lives.”
That is why identity breaches are so dangerous. Criminals can reuse the same stolen data years later to open new accounts, build fake identities or run highly targeted scams that feel personal and convincing. Many attackers now combine this data with AI tools to scale their efforts. As a result, phishing emails, phone calls and even voice impersonations are harder to spot when they reference real details about your bank or account history.
The most likely scams after identity data is stolen
When criminals obtain verified identity data, fraud becomes targeted rather than opportunistic.
“Once criminals get their hands on rich, verified identity data, fraud stops being a guessing game and becomes a targeted execution,” Amper said.
The first major threat is account takeover. With enough personal details, attackers can bypass knowledge-based checks, reset passwords, change contact information and abuse accounts in ways that often look legitimate. The second risk is new account fraud. This includes credit cards, loans, buy now pay later services and even new bank accounts. High-quality data helps these applications pass automated systems and manual reviews.
The fastest-growing threat is synthetic identity fraud. Real data, like a Social Security number, is blended with fabricated details to create a new identity that matures over time before a large financial bust.
“These attacks are hard to catch early because the data being presented is accurate and often reused across multiple institutions,” Amper noted. “If your defenses can’t reliably tell a real human from an AI-generated impersonation, you are starting every decision from a position of disadvantage,” he added.
Why unpatched firewall flaws pose such a serious threat
Ransomware groups like Akira increasingly focus on widely deployed infrastructure to maximize impact. Firewalls sit at the boundary of trusted networks. When one is compromised, everything behind it becomes reachable.
“What we’re seeing with groups like Akira is a focus on maximizing impact by targeting widely used infrastructure. The strategy remains the same: Find a single weak point that gives access to many downstream victims at once,” Amper said.
This approach exposes a persistent blind spot in traditional cybersecurity thinking. Many organizations still assume traffic passing through a firewall is safe.
“When the perimeter device itself is the entry point, static defenses and outdated controls simply can’t keep up,” Amper explained.

How long affected consumers should assume risk remains high
Identity data does not expire. Social Security numbers and birth dates stay the same for life.
“When core identity data reaches criminal markets, the risk does not fade quickly,” Amper emphasized. “Fraud rings treat stolen identity data like inventory. They hold it, bundle it, resell it and combine it with information from new breaches.”
Warning signs of misuse can be subtle. These include credit inquiries you did not authorize, account recovery alerts from unfamiliar services or phone calls that convincingly mimic a bank’s verification process using deepfake voice tools.
“The most damaging fraud often starts long after the breach is no longer in the news,” Amper added.
The overlooked impact of identity theft
Financial losses are only part of the damage. Victims often experience a lasting erosion of trust.
Amper says, “The most overlooked consequence is the psychological toll of knowing that you can no longer trust who is contacting you. Deepfake impersonation turns every phone call, video message or urgent request into a potential attack.”
Ways to stay safe after the Marquis data breach
When a breach exposes Social Security numbers, bank details and birth dates, the risk does not end with a password reset. These steps focus on protections that reduce long-term identity misuse and help you detect fraud early.
1) Freeze your credit with all major bureaus
A credit freeze prevents criminals from opening new accounts in your name using stolen identity data. This is critical after the Marquis breach, where full identity profiles were exposed. Freezing credit does not affect your score and can be lifted temporarily when needed. Place a free credit freeze with Equifax, Experian and TransUnion online or by phone. Each bureau must be contacted separately. Once frozen, new credit cannot be opened unless you temporarily lift or remove the freeze using a PIN or account login.
2) Place a fraud alert on your credit file
A fraud alert tells lenders to take extra steps to verify your identity before approving credit. It adds protection if you are not ready to freeze credit everywhere or want an extra layer on top of a freeze. Fraud alerts last for one year and can be renewed. You only need to contact one credit bureau to place a fraud alert. Equifax, Experian or TransUnion will notify the others for you. Fraud alerts are free and last for one year.
3) Enable transaction and account alerts
Turn on alerts for withdrawal, purchase, login attempts and password changes across all financial accounts. Real-time alerts can help you catch account takeovers or unauthorized activity before serious damage occurs.
4) Review bank statements and credit reports regularly
Check statements and credit reports often, even months or years after the breach. Identity data from incidents like this is frequently reused later for delayed fraud. Watch for unfamiliar accounts, hard inquiries or small test charges.
5) Use phishing-resistant two-factor authentication
Text message codes can be intercepted or socially engineered. Where possible, switch to app-based or hardware-backed two-factor authentication. These options are harder for attackers to bypass, even when they know your personal details.
6) Rely on strong device-based biometrics where available
Biometrics tied to your physical device add a layer that criminals cannot easily replicate. Face and fingerprint authentication help block account takeovers driven by stolen identity data or AI-powered impersonation.
7) Use strong antivirus software
Reputable antivirus software helps detect malicious links, fake login pages and follow-up attacks that target breach victims. This adds protection against phishing and ransomware tied to identity-based scams.
The best way to safeguard yourself from malicious links that install malware, potentially accessing your private information, is to have strong 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.

8) Consider a data removal service
Data brokers collect and resell personal information that can be combined with breach data to fuel targeted fraud. A data removal service reduces how much of your personal information is publicly available and lowers your exposure over time.
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.

9) Add an identity theft protection service
Identity theft services monitor credit files, dark web markets and account activity for signs that your stolen data is being misused. Many also offer recovery assistance in the event of fraud, which can save time and stress when dealing with banks, credit bureaus and government agencies. This monitoring is especially useful after breaches like Marquis, where identity data can resurface long after the initial incident.
See my tips and best picks on how to protect yourself from identity theft at Cyberguy.com.
10) Verify unexpected outreach through official channels
Be cautious of urgent calls, emails or texts that reference real banking or personal details. Scammers now use accurate breach data to sound legitimate. Hang up and contact your bank directly using the number on your card or official website.
11) Lock down tax and government accounts
Create or secure online accounts with the IRS, Social Security Administration and your state tax agency. Enable strong authentication and monitor for unexpected notices. Stolen identity data is often used for tax refund fraud or benefit scams long after a breach.
Kurt’s key takeaways
The Marquis data breach highlights how dangerous unpatched infrastructure vulnerabilities have become for the financial sector. When a single vendor holds data for hundreds of institutions, the fallout spreads quickly. For you, identity protection is no longer a one-time response. It is an ongoing necessity that can last years beyond the initial breach.

You can buy your Xbox Ally an official pair of anti-drift joysticks
Even at $1,000, the Xbox Ally X handheld didn’t ship with magnetic drift-resistant joysticks, and neither did the $600 model. But for an extra $20 at Amazon, you can change that today — with officially Asus-approved and sanctioned TMR joysticks from Gulikit, the company that’s made a name for itself by supplying aftermarket drift-resistant sticks.
The company says it worked with Xbox Ally manufacturer Asus to create these sticks, that they’ll be “automatically recognized” when you swap them in, and that you can use the handheld’s built-in Armoury Crate app to calibrate them afterwards.
And while I haven’t tried these ones (I do have a pair in my Switch), I can confirm it’s pretty easy to pop open the Xbox Ally to install. Just loosen the Philips-head screws, poke in a guitar pick pry tool to create a small gap, and pull a little harder than you think you need to pop open the clips. The joystick modules are right underneath. There’s nothing blocking you — just pop a ribbon cable and undo their three screws.
Here’s the company’s walkthrough in case you want to see for yourself — though I do not recommend taking sharp tweezers to ribbon cables when your fingernails can do that job safer and easier. (I may have broken a few ribbon cables in my life.)
When we’re talking about TMR or the older and slightly less power-efficient Hall effect joystick technology, I usually write “drift-resistant” instead of “drift-free” because you may find your center point drifting over time — but the beauty of magnetic is you just have to recalibrate! Unlike the potentiometer joysticks that ship with Nintendo, Sony PlayStation, and Microsoft Xbox controllers, you’re not scraping away material that’ll lead to permanent drift as you use the magnetic versions.
Gulikit’s new Xbox Ally sticks are $20 in the US today, and should also be available in the UK for £20, and in Italy, France, and Spain for €22, this January.
