Anthropic just released Claude Fable 5, calling it the most powerful AI model it has ever made widely available and praising its skills in biology, among others. But the model won’t answer basic biology questions — the kind you’d expect a high schooler to handle. Instead, it hands off the query to the former flagship model, Claude Opus 4.8.

Your health data is being sold without your consent
NEWYou can now listen to Fox News articles!
Your health information might feel private and secure with your doctor, but the reality is far more complicated. Data brokers collect a wide range of sensitive health data, from diagnoses and prescription details to personal identifiers, and sell this data to marketers, insurers, and other third parties. These buyers use the information to target ads, adjust insurance premiums, or even for purposes you might not expect. Understanding who holds your health data and how it’s used and shared is crucial to protecting your privacy.

Massive health data breaches are fueling the data broker industry
You might think your health data is safe with your doctor. But what if I told you total strangers might know when you last Googled “early signs of dementia” or filled a prescription for anxiety meds, and they’re selling that to whoever is willing to pay for it? A recent data breach at Yale New Haven Health, Connecticut’s largest healthcare system, exposed sensitive information on 5.5 million people. And it’s not an isolated incident; new research shows that since 2020, approximately 94.5 million Americans may have had their Social Security numbers stolen during health data breaches. The scary part is that data brokers collect and sell the names, addresses, and prescribed medications of patients diagnosed with mental health disorders to marketers on a large scale. How much is your medical information worth? Data brokers can sell it for as little as $0.06 per record. Let’s break down what these data brokers know, who they’re selling it to, and why it matters for you, your family, and especially vulnerable groups like seniors.

CUSTOM DATA REMOVAL: WHY IT MATTERS FOR PERSONAL INFO ONLINE
What types of health information are data brokers selling?
There’s a difference between protected health information, the kind your doctor and health insurer have to keep private, thanks to HIPAA, and the health-adjacent data you leave behind everywhere else.
Data brokers typically don’t have access to your official medical records. But they’re not regulated under HIPAA or any other laws, so they can legally collect:
- Fitness app data: Step counts, heart rate, calories burned.
- Symptom-related Google searches: Even “early signs of dementia” or “knee pain at night.”
- Pharmacy purchases: Both prescriptions and over-the-counter medications.
- Wellness quizzes and online forms: Those “What’s your biological age?” surveys aren’t just for fun.
- Social media posts and likes: Public posts about health topics, comments in support groups.
- Location data: Visits to clinics, pharmacies, or addiction recovery centers.
And it doesn’t stop there. Non-health data, like where you shop or the ads you click, gets combined to build a disturbingly accurate health profile.

WHAT HACKERS CAN LEARN ABOUT YOU FROM A DATA BROKER FILE
Why selling your health data is more dangerous than you think
This isn’t harmless marketing data. When health information lands in the wrong hands, it creates real risks:
- Higher insurance premiums or limited coverage based on inferred health risks.
- Scams targeting seniors and vulnerable groups use lists of people flagged for dementia, heart disease, or other conditions.
- Privacy violations, exposing sensitive details like mental health struggles or fertility treatments.
- Discrimination in hiring, housing, or services based on health-related data.
- Resale to unknown third parties, making it impossible to control once it’s out there.
And it’s not just marketers. A recent government-backed autism study led by Robert F. Kennedy Jr. sparked outrage after it was revealed that private health data was collected from federal and commercial databases without clear safeguards. Security experts warn that this kind of large-scale data collection runs the risk of exposing deeply personal information with little oversight.

THINK YOU CAN DELETE YOUR OWN DATA? WHY IT’S HARDER THAN YOU THINK
8 ways to protect your health data from data brokers
Worried about who has access to your health data? While you can’t control every breach or broker, you can take steps to limit what’s collected, shared, and sold. Here’s how to take back control of your digital health footprint-starting today.
1) Use a personal data removal service: Data brokers collect and sell sensitive health information, including diagnoses, prescriptions, and personal identifiers, to marketers, insurers, and other third parties. This means details about your pharmacy purchases, symptom-related searches, and more could be circulating without your knowledge. A personal data removal service can help you take back control. This is one of the most effective ways to safeguard your privacy and protect yourself and your family from risks like scams, higher insurance premiums, and discrimination.
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 here.

2) Audit your apps and privacy settings: Health and fitness apps collect more than you realize. Delete the ones you don’t trust and check permissions on the rest
3) Be wary of free health quizzes and symptom checkers: If a site asks for personal details in exchange for “insights,” assume it’s monetizing your answers. Consult your doctor, not a clickbait quiz.
4) Limit data sharing beyond healthcare providers: Only provide necessary information when signing up for health-related services or apps. Be wary of sharing health details on social media or in public forums, as these can be scraped by data brokers.
5) Request data minimization from providers: Ask your healthcare providers to collect and store only the minimum amount of personal information necessary for your care, reducing the risk if their systems are compromised.
6) Use strong antivirus software: Strong antivirus software acts as a shield, protecting your devices from malware, ransomware, and other cyber threats that could compromise your personal health data. Choose a reputable solution that offers real-time threat detection, regular updates, and robust protection for all your devices. This protection can also alert you to phishing emails and ransomware scams, keeping your personal information and digital assets safe. Keeping your antivirus up to date is crucial for blocking malicious links and downloads before they can do harm. Get my picks for the best 2025 antivirus protection winners for your Windows, Mac, Android & iOS devices.
7) Regularly update your software: Cyber threats targeting health data are constantly evolving, and outdated software can leave your devices vulnerable to attacks that expose your sensitive information. Keeping your operating system, apps, antivirus, and security tools up to date ensures you have the latest protections against malware, ransomware, and other exploits that data brokers or hackers might use to access your health information. Regular updates patch security holes before they can be exploited, helping to prevent breaches like those that have exposed millions of Americans’ health details in recent years.
8) Use strong and unique passwords: Your health data is often protected by passwords on apps, portals, and devices. Using strong, unique passwords for each account reduces the risk that a single breach could give someone access to multiple sources of your personal information. Avoid common or reused passwords, and consider using a password manager to generate and store complex passwords securely. This step is crucial because once your login credentials are compromised, data brokers or cybercriminals can gather and sell your health-related data, leading to privacy violations, discrimination, or targeted scams. Consider using a password manager to generate and store complex passwords. Get more details about my best expert-reviewed Password Managers of 2025 here.
Kurt’s key takeaways
Your health should be personal, but in today’s digital world, that privacy is constantly under threat. Even if you’re cautious, your health-related information can be collected, analyzed, and sold without your clear consent. The good news is that you can take real steps to reduce your exposure and protect what matters. This isn’t about fear; it’s about staying informed and taking control of your digital footprint.

Bluesky will be getting “communities,” which will function as smaller spaces where you can “go deeper and hang out with people who care about the same stuff” sometime this year, according to head of product Alex Benzer. They will be built on the decentralized AT Protocol that underpins Bluesky, with Benzer saying that “it’s a new structure for everyone” that’s part of the “Atmosphere” (a shorthand for the AT Protocol ecosystem).
Benzer listed out a “few ideas we have in mind so far” in a thread. “On Bluesky, you’ll be able to create communities, join them, post in them, and get updates,” Benzer says. “The core features on Bluesky stay simple. The magic comes from communities also existing on the open web. This means you can truly customize them and add features with other Atmospheric apps and tools.”
Communities will get a handle that “doubles as a URL,” and if you go to that URL, you’ll “land on a custom homepage for the community,” according to Benzer. “Builders can also host a completely custom experience there instead.” There will be three privacy levels for communities: public, invite-only, and private. And each community would have its own feed, Benzer says.
Benzer’s thread follows Bluesky COO Rose Wang saying last week that the company wanted to move away from being a “public square” and that it was “very inspired by companies like Reddit.” Meta’s Threads is currently testing a communities feature, while X announced in April that it would be shutting down its own take on communities.

Amazon is getting ready for Prime Day, and you can bet scammers are, too. In fact, I received a fake Amazon email that looked like an account recovery warning. It claimed there was unusual activity on my account and pushed me to “Sign In to Verify.”
That kind of message can make anyone uneasy. It certainly did for me. After all, who wants to lose access to an account right before a major sale? Then came the part that really stood out: the email said I might need to upload a document to confirm my account.
That was the giveaway. A real deal can save you money. A fake Amazon email can cost you your login, your payment details and even your identity.
Here’s how this scam works, the red flags that exposed it and the steps you should take before clicking any Amazon account warning.

Fake Amazon email warning before Prime Day
The timing made this phishing email more convincing. With Prime Day coming up, many people are already watching for Amazon emails. They may be checking delivery updates, deal alerts and order confirmations. That creates the perfect opening for a fake account warning.
The email used the same tricks you see in many phishing scams. It claimed there was account trouble, used urgent language and pushed me toward a sign-in button. That is exactly what scammers want.

They want you to react before you inspect the message. They want you to sign in before you think through the request. And in this case, they wanted me to believe a document upload was part of a normal Amazon account check.
Amazon phishing scam red flags
This fake Amazon email had several warning signs. First, it landed in my junk folder. That alone does not prove fraud, but it should make you cautious.
Second, the subject line sounded awkward. It said, “Account Recovery: Sign-in and Verify your Amazon account.” That wording felt stiff and a little off.
Third, the greeting was generic. The email said “Dear Customer” even though it claimed to be about my Amazon account. That alone does not prove the email is fake, but it adds to the concern.
Fourth, the message created urgency. It claimed the account was on hold and that orders or subscriptions had already been canceled.
Fifth, the sender display name said “Amazon,” while the address appeared as account_update@amazon.com. That may look official at first. Still, scammers can spoof sender names or make email addresses look convincing.
Under the yellow “Sign In to Verify” button, the email also says, “Don’t share it with others.” That may sound protective, but in this context, it felt like another attempt to make the fake warning seem official.
The biggest warning sign came from the document request. The email said I would have the option to upload a document with the required information to verify the account.
That should stop you cold. Scammers may be after more than your Amazon password. They may also want your driver’s license, passport, address, phone number or payment details.

Why fake Amazon account emails fool shoppers
This scam works because it hits a very real fear. Most people do not want to lose access to an online shopping account. That concern grows when a big sale is about to start. If you are planning to buy something on Prime Day, an account warning can feel urgent.
The email also borrowed Amazon’s familiar look. It used the Amazon name, a logo area and a yellow sign-in button. It also included a footer that appeared to show an Amazon.com link. That can make the message feel safer than it really is.
Here is the problem. The visible link text in an email can mislead you. A link can appear to point to Amazon while sending you somewhere else. It can also pass through tracking links, redirects or look-alike pages. That is why you should avoid signing in through any account warning email.

What happens if you click a fake Amazon link
If you click the link, you may land on a fake Amazon sign-in page. It may look close enough to fool you. Once you enter your email and password, scammers can try to access your real Amazon account. They may check your saved payment methods, shipping addresses and order history.
They may also try that same password on other websites. That becomes a bigger risk if you reuse passwords.
The document request adds another layer of danger. If a fake page asks for your ID, scammers could use that information for identity theft, account takeovers or other fraud. That is why one quick click can turn into a much bigger mess.
Ways to stay safe from fake Amazon emails
A fake Amazon email can look convincing at first, so the best move is to slow down and use these simple checks before you click, sign in or share anything.
1) Do not click the sign-in button
Skip buttons like “Sign In to Verify,” “View details” or “Restore access.” Open the Amazon app or type Amazon.com into your browser yourself.
2) Check Amazon’s Message Center
After signing in directly, go to Your Account > Message Center. If the alert is real, you should see a matching message there.
3) Watch for pressure language
Scammers often say your account is locked, your orders were canceled, or you must act right away. That pressure is designed to make you click before thinking.
4) Never upload ID through an email link
If an email asks for a passport, driver’s license or other document, stop. Contact Amazon through the app or website before sending anything.
5) Use a password manager
A password manager can help you spot fake login pages. If the page is fake, your saved Amazon password usually will not autofill. Check out the best expert-reviewed password managers of 2026 at CyberGuy.com.
6) Turn on two-step verification
7) Use strong antivirus software
Install strong antivirus software on your computer, phone and tablet. Good security software can help detect malicious links, phishing pages, malware and other threats before they do damage. This is especially important if you clicked a suspicious link or downloaded anything from a fake email. Security software should back up your smart habits, not replace them. Get my picks for the best 2026 antivirus protection winners for your Windows, Mac, Android and iOS devices at CyberGuy.com.
8) Use a data removal service
Scammers often build more convincing attacks with information they find about you online. That can include your name, address, phone number, relatives, old usernames and other personal details from people-search sites and data brokers. A data removal service can help remove your personal information from many of those sites. That makes it harder for scammers to personalize phishing emails and identity theft attempts. 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.
9) Report the suspicious email
Forward suspicious Amazon emails to reportascam@amazon.com. Then delete the message from your inbox or junk folder.

Kurt’s key takeaways
Prime Day is a great time to find real deals, but it is also a busy season for fake Amazon emails. Scammers know shoppers are checking delivery updates, watching for discounts and hoping nothing gets in the way of a good buy. That is what made this email so sneaky. It used a familiar fear at the perfect moment: losing access to your account right before a major sale. The safest move is to slow down before you click. Do not trust the button. Do not trust the sender name alone. Open the Amazon app or type Amazon.com into your browser and check your account yourself.

HOW TO DETECT FAKE AMAZON EMAILS AND AVOID IMPERSONATION SCAMS
Copyright 2026 CyberGuy.com. All rights reserved.
It isn’t because Fable doesn’t know the answers. It’s because Anthropic won’t let it, by design.
Fable is a public-facing, Mythos-class model, a family so capable at cybersecurity tasks Anthropic said it was too dangerous to release publicly. But while Anthropic has spent much of the extended Mythos rollout warning about cybersecurity, it is biology where Fable’s guardrails are the most obvious — and most limiting.
When I tried the model, it refused to answer a range of basic biology questions, many that felt about as far away from any plausible safety risk as any question could be. It would not respond to “tell me about cell membranes” or answer “what are mitochondria,” that famous powerhouse of the cell. It refused to explain “what is a prion,” the proteinaceous particles behind mad cow disease, or “how mRNA vaccines work.”
“We made this tradeoff so customers could benefit from the model’s capabilities sooner without the risks.”
The restrictions applied to ordinary and objectively rather harmless medical queries too. Fable would not answer “what causes hay fever,” explain how asthma medicine works, explain how antibiotic resistance arises, or tell me what Ebola is and how it spreads. Some of my basic queries occasionally got through, with Fable answering questions like “what is cancer” and “what is DNA.” When Fable refused, Opus 4.8 generally answered perfectly well.
Anthropic says the broad biology filters are an intentional choice and are deliberately conservative, with bioweapons the primary concern. “With the launch of Claude Fable 5, our first Mythos-class model, we believe models now have a greater ability to accomplish real-world scientific tasks and for malicious actors to potentially use our models for highly risky biological research,” spokesperson Paruul Maheshwary told The Verge. “We have always used classifiers to block our models from helping with bioweapons-related requests. To deploy Fable 5 safely, we believe it was necessary to be overly conservative with our safeguards so they block most queries tied to biology work.”
Anthropic has previously highlighted four key areas where it would throttle Fable’s responses for safety: chemistry, biology, cybersecurity, and distillation, a technique for training smaller AIs using the outputs of larger ones. The company has accused Chinese rivals like DeepSeek of using distillation on its models on an “industrial” scale.
While I could not meaningfully test distillation, Fable seemed more willing to answer questions about chemistry and cybersecurity. For example, it gave a basic overview of the explosive TNT, though withheld synthesis instructions “for obvious reasons.” It readily answered questions on the use of chlorine gas as a chemical weapon, common password threats, and nuclear fusion and fission, as well as explaining how to secure an iPhone from hackers. It still limits: Fable deferred to Opus when I asked it about sarin gas, a highly toxic nerve agent. Fable and Opus both refused the prompt “how to make anthrax,” and Claude paused the chat entirely. That made sense. The mitochondria prompt refusal seems like a false positive.
“We made this tradeoff so customers could benefit from the model’s capabilities sooner without the risks,” Maheshwary explained, adding that Anthropic is working hard to improve its detection and reduce the false positives. “We intend to make Mythos-class models available without these safeguards to the broader biology and life sciences community so these capabilities can be used to accelerate biomedical research and drug discovery.”
Anthropic did not answer questions about whether this kind of restricted release will become the new norm for future models.
