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.

How thieves use new credit card numbers before you receive them
Imagine receiving a notification about suspicious charges on a credit card you haven’t even received yet. How could that happen?
While it sounds surprising and unsettling, it’s increasingly common due to the rise of digital credit card fraud. Criminals no longer need physical cards to make unauthorized transactions, thanks to methods such as data breaches, phishing schemes and card-not-present fraud.
Here’s how these schemes work and what steps you should take immediately to protect yourself.

How it happens
Even if a new credit card hasn’t arrived yet, it may already be vulnerable. In many cases, the issue isn’t about the card being physically stolen but about someone gaining access to your information digitally. Criminals can exploit online account features, mobile wallets or leaked personal data to start using your card before you’ve even opened the envelope. Below are some of the most common ways this type of fraud happens.
1. Account takeover or access
If a scammer already has access to your account, either through stolen login credentials, a hacked email or malware, they can view the newly issued card number in the online dashboard or mobile app. Many credit card companies now allow instant access to digital card numbers for use in Apple Pay, Google Wallet or online purchases. This means that as soon as a new card is issued, it may be visible digitally before the physical card is even shipped. If a fraudster has access to your account, they can add the number to a digital wallet and begin spending before the envelope ever hits your mailbox.
2. Digital wallet hijack
Some card issuers allow you to add your credit card to mobile wallets instantly, even before the physical card arrives. While this feature is convenient, it can also expose you to specific security risks tied to mobile wallet activation. Criminals may exploit this process by using stolen personal information to bypass security checks and add your card to their own Apple Pay or Google Wallet accounts. They might pose as you to request a new card, intercept or reroute the digital activation process, or even start making fraudulent purchases immediately. This type of fraud can be hard to detect, especially if you’re not expecting a new card or if unauthorized charges blend in with legitimate transactions.

THIS IS HOW TO PROTECT YOUR CREDIT AND BANK CARDS FROM GETTING HACKED
3. Phishing or data breaches
Another common scenario involves your personal information being compromised in a phishing attack or large-scale data breach. Thieves use this stolen data, such as your name, Social Security number, address and security question answers, to impersonate you and gain access to your account dashboard or reset login credentials. Once inside, they can retrieve new card details directly from the source or request a replacement card. Phishing scams often trick victims into revealing sensitive information through fake emails or websites, while data breaches expose vast amounts of personal data that criminals can exploit for fraudulent activities.
4. Mail theft
Although charges made before a new credit card is received are rarely due to mail theft, this type of traditional fraud still poses a risk. Criminals may intercept your mail to steal sensitive documents, including credit cards, which can then be used for unauthorized purchases. To reduce this risk, avoid leaving important mail unattended in your mailbox. Consider using Informed Delivery by USPS to track incoming mail or request that your credit card be delivered to a secure location, such as a P.O. box or directly to your bank branch.

What to do immediately
If you find yourself in this situation where fraudulent charges appear on a card you haven’t received yet, take these steps right away.
1. Change login credentials: Update all login information with your bank or credit card company, including:
- New password
- Security questions
- PIN (if applicable)
If your account is linked to an email address that may also be compromised, update the password for that email account as well. Many fraudsters gain access by first hacking your email, which can give them entry to password-reset links and sensitive notifications. Consider using a password manager to generate and store complex passwords. Get more details about my best expert-reviewed password managers of 2025 here.
2. Use strong antivirus software: If spyware or a keylogger has been installed on your device, it can continue to steal sensitive data, such as passwords and personal information, even after you change your credentials. To protect yourself, install strong antivirus software on all your devices. Get my picks for the best 2025 antivirus protection winners for your Windows, Mac, Android and iOS devices.
3. Enable multifactor authentication (MFA): Add MFA to all accounts tied to your financial information. This adds an extra layer of security by requiring a second verification step (e.g., a code sent to your phone) before accessing sensitive accounts.
4. Use an identity theft protection service: Identity theft companies can monitor personal information like your Social Security number, phone number and email address and alert you if it is being sold on the dark web or being used to open an account. They can also assist you in freezing your bank and credit card accounts to prevent further unauthorized use by criminals. See my tips and best picks on how to protect yourself from identity theft.
5. Invest in personal data removal services: Consider using a personal data removal service to reduce your online exposure. These services continuously monitor and remove your sensitive information from data brokers and websites that could be exploited by criminals. This lowers the chances of your data being used in phishing scams or other fraudulent activities. 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.
6. Ask your credit card company to investigate: Contact your credit card provider directly and request a full investigation. Ask if there was any suspicious account activity, such as a login from a new device, before the fraudulent charges occurred. They may be able to trace when and how your account was accessed. Most card issuers will reverse fraudulent charges and can reissue a new card with a different number.
7. Notify law enforcement: File a report with the Federal Trade Commission. If necessary, a police report should also be filed to document the fraud. This can be helpful for disputing charges and clearing your record.
DON’T LET THIS CREDIT CARD FRAUD NIGHTMARE HAPPEN TO YOU
Kurt’s key takeaways
So, we’ve uncovered how those sneaky credit card charges can surface even before you’ve held the card in your hands. It’s a reflection of the increasingly digital world we live in, where our personal information can be vulnerable in surprising ways. Remember, use strong antivirus software and consider a personal data removal service to minimize your online footprint. If you find yourself in this situation, act fast by changing your passwords, enabling multifactor authentication and reporting the issue to your card company.

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.
