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.

Fake Venmo accounts are stealing donations from real charities
NEWYou can now listen to Fox News articles!
Apps like Venmo, Zelle, Cash App, and PayPal have changed how we move money. They are fast and convenient, but with that ease comes exposure. If you send funds to the wrong person, they are likely gone for good. There is often no real path to recovery, especially when the recipient disappears behind a fake username and an unresponsive support system.
This vulnerability becomes even more dangerous in moments of crisis. During natural disasters, high-profile social movements, or health emergencies, people are moved to give. Scammers know this and exploit the impulse. One such scam involved a fake Venmo account pretending to collect donations for a Minnesota nonprofit after the death of George Floyd. The account looked legitimate, but the funds never reached the organization.
A similar scam is targeting Miles Perret Cancer Services, a nonprofit based in Louisiana. Scammers have created a fraudulent Venmo account that closely mimics the legitimate Venmo handle of the cancer nonprofit organization. They are using this fake account to trick well-meaning donors into sending money, believing they are supporting the real charity.

Fake Venmo account mimics real charity: How 1 character can fool you
Miles Perret Cancer Services (MPCS) provides support to families facing cancer diagnoses. They recently discovered that a fraudulent Venmo account is impersonating their official one. Their real handle is @milesperretcs. The scammer’s account uses @milesperretcs_, a nearly indistinguishable copy.
To the average person, the difference is invisible. That is precisely what makes it dangerous.
“We reported this account through the app more than 24 hours ago,” Timothy Rinaldi, executive director of MPCS, told Cyberguy. “There has been no follow-up from Venmo. We tried the live chat option, but it was abruptly closed with no resolution.”
Instead of helping, Venmo routed Rinaldi through generic FAQs and legal disclaimers. Even after he was connected with a live support agent, the responses were standard scripts. He was told that the issue had been escalated, but no one could provide a timeline beyond a vague window of three to five business days.

Charity scams on Venmo: How scammers trick donors using fake accounts
Fake Venmo accounts have been used in recent years to exploit donation drives for hurricane relief, animal shelters, medical funds, and other causes. The formula is simple. Take a known nonprofit, tweak the username slightly, and ride the momentum of goodwill. By the time anyone catches on, the money is gone and the damage is done.
The incident involving MPCS is not an isolated case. In December 2024, Final Victory Animal Rescue, a nonprofit based in South Carolina, discovered a Venmo account impersonating the organization and collecting donations intended for the real charity. The group’s general manager, Michael Sniezek, confirmed the account had been receiving funds from unsuspecting donors before the issue was flagged.
In another case, Alone No More Dog Rescue, a Phoenix-based nonprofit, posted on Facebook that fraudulent Venmo accounts had been targeting its past donors, sending them payment requests and soliciting additional funds under false pretenses.
MPCS has filed a report with the Federal Trade Commission, but there is no guarantee of quick resolution. The fraudulent account remains active as of press time. It is unclear how much has already been lost or whether Venmo will recover and return any of it.

THIS IS WHAT YOU ARE DOING WRONG WHEN SCAMMERS CALL
Venmo confirms fake accounts were removed and shares how to stay safe
Venmo confirmed that the imposter accounts were removed promptly after being reported. They recommend reporting suspicious activity directly within the Venmo app and contacting customer support for further assistance.
To help users avoid future scams, Venmo encourages everyone to review its official security tips on how to recognize impersonation attempts and learn how to spot and avoid charity-related scams.
They also shared the following tips to help users verify real Venmo profiles and stay safe when sending money:
- Double-check the Venmo username (handle): Look closely for misspellings, extra characters or attempts at impersonation.
- Use Venmo QR codes: Scan QR codes directly from the Venmo app to ensure you’re sending money to the right person.
- Donate only to verified Venmo charity accounts: These are vetted and marked with verification badges. You can find them here.
Heed Venmo’s automatic warnings: If Venmo flags a payment as suspicious, pause and verify before sending money. These alerts are designed to protect you from scams.
How to avoid Venmo scams: 11 expert tips to protect your money
Scammers aren’t just targeting charities. They’re after anyone and everyone. Here are a few ways to protect yourself and keep your hard-earned money safe.
1) Always access the payment app from the official app or website, and not from any third-party platforms or services.
2) Look at the security settings that the payment app offers and make sure they’re all set to the highest and most protective settings.
3) Consider using a personal data removal service to protect your privacy and reduce your risk of scams. Scammers who target payment apps like Venmo, Zelle, Cash App, and PayPal often rely on information found on data broker and people-search sites to craft convincing impersonations or phishing attempts. These sites can list your name, address, phone number, and even connections to organizations you support, making it easier for fraudsters to trick you or others into sending money to fake accounts.
Personal data removal services work by automatically removing your information from hundreds of data broker sites, making it much harder for scammers to find and misuse your details. By scrubbing your data from these sources, you lower your risk of being targeted in payment app scams and reduce the likelihood that someone could impersonate you or a nonprofit you care about. Check out my top picks for data removal services here.

4) Create a strong, unique and complex password for each of your mobile payment apps and change it often. Consider using a password manager to generate and store complex passwords. Get more details about my best expert-reviewed password managers of 2025 here.
5) Enable two-factor authentication, which means that you need to enter a code or use your fingerprint or face to unlock your account to prevent unauthorized access. This way, even if someone knows your password, they can’t log in without your device or confirmation.
6) Lock your device and log out of your apps. You should always lock your phone with a password, PIN, pattern, fingerprint, or face. Never share your password, PIN, or security code with anyone. You should also log out of your mobile payment apps after each use and turn off the auto-login feature. This way, even if someone takes or borrows your device, they can’t access your mobile payment apps without your approval.
7) Verify the identity and legitimacy of the sender or receiver. You should always check the name, photo, username, and contact information of the person or organization you are sending money to or receiving money from before accepting or sending any payment requests. You should also confirm the reason and amount of the transaction before you agree to it. If you are not sure or have any doubts, you should contact the person or organization directly through another way, such as a phone call, text message, or email, but only if you know for sure that those forms of communication are legitimate. You should never send money or give your account details to anyone you don’t know or trust, or anyone who asks you to do so out of the blue.
8) Link your Venmo to a credit card as opposed to a debit card, so you can dispute a charge from scammers more easily. However, keep in mind, linking a credit card to your payment app can provide additional protection in the event of fraud, but this can come with extra costs in terms of transaction fees.
9) Try not to keep a balance in your money-transferring apps. You have a much better chance of being helped by your bank or credit card company when it comes to fraud than you do from a money-transferring app.
10) Use strong antivirus software and never click on links from unknown sources, especially when an email or text appears to have come from the payment App. Protect yourself from accidentally clicking on malicious links by running antivirus software on your device.
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 2025 antivirus protection winners for your Windows, Mac, Android and iOS devices.
11) Monitor your account activity and report any suspicious or unauthorized transactions. You should set up notifications from your payment app and your bank via text or email, and check your account activity regularly. Look for any signs of fraud, such as payments you didn’t make or receive, or changes to your account settings or information.
Kurt’s key takeaway
Unlike traditional banks, which are bound by federal consumer protection laws and fraud resolution timelines, peer-to-peer payment apps operate in a much looser regulatory environment. Services like Venmo often state in their user agreements that they are not responsible for mistaken or unauthorized payments unless there is clear evidence of account compromise or technical malfunction. Venmo’s only suggestion here was to respond to a support ticket and wait. There was no emergency fraud hotline, no dedicated contact for nonprofits, and no indication that urgent action would be taken. Payment apps that allow donations to flow as quickly as a text message must also bear the responsibility of keeping those transactions safe. When a nonprofit has to beg for support just to protect its own identity, something is broken.

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.
