5.5 million patients' information exposed by major healthcare data breach
Healthcare seems to be the favorite target of attackers this year. It’s been only four months, and we’ve already seen some of the biggest data breaches in the sector. Recently, news about the Blue Shield of California data breach came to light, leaking the personal data of 4.7 million people.
But if that wasn’t enough, Connecticut’s largest healthcare system, Yale New Haven Health, has now revealed that a data breach affected more than 5.5 million people.
The information leaked included patient names, dates of birth, postal and email addresses, phone numbers and more.

What you need to know
According to a legally mandated disclosure with the U.S. Department of Health and Human Services, Yale New Haven Health experienced a cyberattack on March 8 that allowed malicious hackers to obtain copies of patients’ personally identifiable information as well as some healthcare-related data.
Yale New Haven Health is a nonprofit healthcare system based in New Haven, Connecticut. It includes five acute-care hospitals, a medical foundation, and a network of outpatient facilities and multispecialty centers across Connecticut, New York and Rhode Island.
WHAT IS ARTIFICIAL INTELLIGENCE (AI)?
In a notice posted on its website, the healthcare system said the stolen data varied by individual but could include names, dates of birth, postal and email addresses, phone numbers, race and ethnicity information, Social Security numbers, types of patients and medical record numbers. Reportedly, the number of affected individuals may still change as investigations continue. Importantly, electronic medical record systems and treatment information were not accessed, and no financial account, payment or employee HR information was involved.
This is not the first time healthcare systems have been in the crosshairs of cybercriminals. In recent years, attacks on institutions like UnitedHealth and Ascension Health have led to months of operational disruption, massive financial costs and prolonged investigations.

What Yale New Haven Health is doing
Yale New Haven Health brought in cybersecurity firm Mandiant to assist with the investigation and said a rapid response helped contain the incident and prevent any disruption to patient care. The organization noted that it regularly updates and strengthens its systems to protect sensitive data and will continue those efforts. Notification letters began going out to affected individuals on April 14, and complimentary credit monitoring and identity theft protection services have been offered to those whose Social Security numbers were compromised.
The breach could have serious consequences for those impacted. The stolen data includes highly sensitive information that can be used for identity theft, financial fraud, phishing attacks or targeted scams. Healthcare data is especially valuable on the black market because it can be exploited for long periods without easy detection. Even if Social Security numbers or medical information aren’t misused right away, the long-term risk for affected individuals remains significant.
We reached out to Yale New Haven Health (YNHHS), and a health system spokesperson said in part:
“We take our responsibility to safeguard patient information incredibly seriously, and we regret any concern this incident may have caused. We are continuously updating and enhancing our systems to protect the data we maintain and to help prevent events such as this from occurring in the future. For more information on this incident, patients may visit YNHHS’ website at ynhhs.org or call our dedicated, toll-free call center at 1-855-549-2678, Monday through Friday, between 9:00 am and 9:00 pm Eastern Time, excluding major U.S. holidays.”

MALWARE EXPOSES 3.9 BILLION PASSWORDS IN HUGE CYBERSECURITY THREAT
5 ways you can stay safe from insurance data breach
If your information was part of the Yale New Haven Health breach or any similar one, it’s worth taking a few steps to protect yourself.
1. Consider identity theft protection services: Since the Yale New Haven Health data breach exposed personal and financial information, it’s crucial to stay proactive against identity theft. Identity theft protection services offer continuous monitoring of your credit reports, social security number, and even the dark web to detect if your information is being misused. These services send you real-time alerts about suspicious activity, such as new credit inquiries or attempts to open accounts in your name, helping you act quickly before serious damage occurs. Beyond monitoring, many identity theft protection companies provide dedicated recovery specialists who assist you in resolving fraud issues, disputing unauthorized charges and restoring your identity if it’s compromised. See my tips and best picks on how to protect yourself from identity theft.
2. Use personal data removal services: The Yale New Haven Health data breach leaks loads of information about you, and all this could end up in the public domain, which essentially gives anyone an opportunity to scam you.
One proactive step is to consider personal data removal services, which specialize in continuously monitoring and removing your information from various online databases and websites. While no service promises to remove all your data from the internet, having a removal service is great if you want to constantly monitor and automate the process of removing your information from hundreds of sites continuously over a longer period of time. Check out my top picks for data removal services here.
3. Have strong antivirus software: Yale New Haven Health hackers have people’s email addresses and full names, which makes it easy for them to send you a phishing link that installs malware and steals all your data. These messages are socially engineered to catch them, and catching them is nearly impossible if you’re not careful. However, you’re not without defenses..
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. Get my picks for the best 2025 antivirus protection winners for your Windows, Mac, Android and iOS devices
4. Enable two-factor authentication: While passwords weren’t part of the data breach, you still need to enable two-factor authentication (2FA). It gives you an extra layer of security on all your important accounts, including email, banking and social media. 2FA requires you to provide a second piece of information, such as a code sent to your phone, in addition to your password when logging in. This makes it significantly harder for hackers to access your accounts, even if they have your password. Enabling 2FA can greatly reduce the risk of unauthorized access and protect your sensitive data.
5. Be wary of mailbox communications: Bad actors may also try to scam you through snail mail. The data leak gives them access to your address. They may impersonate people or brands you know, and use themes that require urgent attention, such as missed deliveries, account suspensions and security alerts.
WINDOWS 10 SECURITY FLAWS LEAVE MILLIONS VULNERABLE
Kurt’s key takeaway
While Yale New Haven has been working with security experts to contain the breach and notify those affected, it is troubling that hackers were able to access the data of 5.5 million individuals before the organization detected the intrusion. The incident highlights a deeper issue, revealing gaps in the security infrastructure that many healthcare institutions are still not adequately addressing.

Defense secretary Pete Hegseth designates Anthropic a supply chain risk
This week, Anthropic delivered a master class in arrogance and betrayal as well as a textbook case of how not to do business with the United States Government or the Pentagon.
Our position has never wavered and will never waver: the Department of War must have full, unrestricted access to Anthropic’s models for every LAWFUL purpose in defense of the Republic.
Instead, @AnthropicAI and its CEO @DarioAmodei, have chosen duplicity. Cloaked in the sanctimonious rhetoric of “effective altruism,” they have attempted to strong-arm the United States military into submission – a cowardly act of corporate virtue-signaling that places Silicon Valley ideology above American lives.
The Terms of Service of Anthropic’s defective altruism will never outweigh the safety, the readiness, or the lives of American troops on the battlefield.
Their true objective is unmistakable: to seize veto power over the operational decisions of the United States military. That is unacceptable.
As President Trump stated on Truth Social, the Commander-in-Chief and the American people alone will determine the destiny of our armed forces, not unelected tech executives.
Anthropic’s stance is fundamentally incompatible with American principles. Their relationship with the United States Armed Forces and the Federal Government has therefore been permanently altered.
In conjunction with the President’s directive for the Federal Government to cease all use of Anthropic’s technology, I am directing the Department of War to designate Anthropic a Supply-Chain Risk to National Security. Effective immediately, no contractor, supplier, or partner that does business with the United States military may conduct any commercial activity with Anthropic. Anthropic will continue to provide the Department of War its services for a period of no more than six months to allow for a seamless transition to a better and more patriotic service.
America’s warfighters will never be held hostage by the ideological whims of Big Tech. This decision is final.

What Trump’s ‘ratepayer protection pledge’ means for you
NEWYou can now listen to Fox News articles!
When you open a chatbot, stream a show or back up photos to the cloud, you are tapping into a vast network of data centers. These facilities power artificial intelligence, search engines and online services we use every day. Now there is a growing debate over who should pay for the electricity those data centers consume.
During President Trump’s State of the Union address this week, he introduced a new initiative called the “ratepayer protection pledge” to shift AI-driven electricity costs away from consumers. The core idea is simple.
Tech companies that run energy-intensive AI data centers should cover the cost of the extra electricity they require rather than passing those costs on to everyday customers through higher utility rates.
It sounds simple. The hard part is what happens next.

Why AI is driving a surge in electricity demand
AI systems require enormous computing power. That computing power requires enormous electricity. Today’s data centers can consume as much power as a small city. As AI tools expand across business, healthcare, finance and consumer apps, energy demand has risen sharply in certain regions.
Utilities have warned that the current grid in many parts of the country was not built for this level of concentrated demand. Upgrading substations, transmission lines and generation capacity costs money. Traditionally, those costs can influence rates paid by homes and small businesses. That is where the pledge comes in.
What the ratepayer protection pledge is designed to do
Under the ratepayer protection pledge, large technology companies would:
- Cover the full cost of additional electricity tied to their data centers
- Build their own on-site power generation to reduce strain on the public grid
Supporters say this approach separates residential energy costs from large-scale AI expansion. In other words, your household bill should not rise simply because a new AI data center opens nearby. So far, Anthropic is the clearest public backer. CyberGuy reached out to Anthropic for a comment on its role in the pledge. A company spokesperson referred us to a tweet from Anthropic Head of External Affairs Sarah Heck.
“American families shouldn’t pick up the tab for AI,” Heck wrote in a post on X. “In support of the White House ratepayer protection pledge, Anthropic has committed to covering 100% of electricity price increases that consumers face from our data centers.”
That makes Anthropic one of the first major AI companies to publicly state it will absorb consumer electricity price increases tied to its data center operations. Other major firms may be close behind. The White House reportedly plans to host Microsoft, Meta and Anthropic in early March to discuss formalizing a broader deal, though attendance and final terms have not been confirmed publicly.
Microsoft also expressed support for the initiative.
“The ratepayer protection pledge is an important step,” Brad Smith, Microsoft vice chair and president, said in a statement to CyberGuy. “We appreciate the administration’s work to ensure that data centers don’t contribute to higher electricity prices for consumers.”
Industry groups also point to companies such as Google and utilities including Duke Energy and Georgia Power as making consumer-focused commitments tied to data center growth. However, enforcement mechanisms and long-term regulatory details remain unclear.

How this could change the economics of AI
AI infrastructure is already one of the most expensive technology buildouts in history. Companies are investing billions in chips, servers and real estate. If firms must also finance dedicated power plants or pay premium rates for grid upgrades, the cost of running AI systems increases further. That could lead to:
- Slower expansion in some markets
- Greater investment in renewable energy and storage
- More partnerships between tech firms and utilities
Energy strategy may become just as important as computing strategy. For consumers, this shift signals that electricity is now a central part of the AI conversation. AI is no longer only about software. It is also about infrastructure.
The bigger consumer tech picture
AI is becoming embedded in smartphones, search engines, office software and home devices. As adoption grows, so does the hidden infrastructure supporting it. Energy is now part of the conversation around everyday technology. Every AI-generated image, voice command or cloud backup depends on a power-hungry network of servers.
By asking companies to account more directly for their electricity use, policymakers are acknowledging a new reality. The digital world runs on very physical resources. For you, that shift could mean more transparency. It also raises new questions about sustainability, local impact and long-term costs.

What this means for you
If you are a homeowner or renter, the practical question is simple. Will this protect my electric bill? In theory, separating data center energy costs from residential rates could reduce the risk of price spikes tied to AI growth. If companies fund their own generation or grid upgrades, utilities may have less reason to spread those costs among all customers.
That said, utility pricing is complex. It depends on state regulators, long-term planning and local energy markets.
Here is what you can watch for in your area:
- New data center construction announcements
- Utility filings that mention large commercial load growth
- Public service commission decisions on rate adjustments
Even if you rarely use AI tools, your community could feel the effects of a nearby data center. The pledge is intended to keep those large-scale power demands from showing up in your monthly bill.

Kurt’s key takeaways
The ratepayer protection pledge highlights an important turning point. AI is no longer only about innovation and speed. It is also about energy and accountability. If tech companies truly absorb the cost of their expanding power needs, households may avoid some of the financial strain tied to rapid AI growth. If not, utility bills could become an unexpected front line in the AI era.

Here’s your first look at Kratos in Amazon’s God of War show
Amazon has slowly been teasing out casting details for its live-action adaptation of God of War, and now we have our first look at the show. It’s a single image but a notable one showing protagonist Kratos and his son Atreus. The characters are played by Ryan Hurst and Callum Vinson, respectively, and they look relatively close to their video game counterparts.
There aren’t a lot of other details about the show just yet, but this is Amazon’s official description:
The God of War series storyline follows father and son Kratos and Atreus as they embark on a journey to spread the ashes of their wife and mother, Faye. Through their adventures, Kratos tries to teach his son to be a better god, while Atreus tries to teach his father how to be a better human.
That sounds a lot like the recent soft reboot of the franchise, which started with 2018’s God of War and continued through Ragnarök in 2022. For the Amazon series, Ronald D. Moore, best-known for his work on For All Mankind and Battlestar Galactica, will serve as showrunner. The rest of the cast includes: Mandy Patinkin (Odin), Ed Skrein (Baldur), Max Parker (Heimdall), Ólafur Darri Ólafsson (Thor), Teresa Palmer (Sif), Alastair Duncan (Mimir), Jeff Gulka (Sindri), and Danny Woodburn (Brok).
While production is underway on the God of War series, there’s no word on when it might start streaming.
