Scammers are targeting hundreds of thousands of crypto owners after Trezor confirms a data breach. I'm Imran Shaikh and pop that bottle of champagne because your weekend edition of the Daily Crunch starts right now. Demand for OpenAI's newest and most powerful model, Astra, has led the company to temporarily pause subscriptions for its$200 per month pro plan, citing strain on its infrastructure.

3:03You see, the move was announced on X by OpenAI's product leader, Tipo Sotio, who leads core products like Codex and ChatGPT at the AI lab. He said that the pro plan puts the most strain on its systems, which is why sign-ups for the service tier are now being disabled. We wanted to take the smallest step that allows us to continue giving the broadest access possible, Sotio wrote. He added that the company's other plans, including the API and lower-cost Go and Plus plans, remain available. Now, to be fair, the company did warn on Wednesday that such a change might come. A new report released on Thursday by Anthropic, alleged persistent distillation attacks by China-based AI companies, which have escalated in recent months as competition in the space has intensified.

3:51Over the last several months, unauthorized labs have developed increasingly sophisticated methods to circumvent our defenses and harvest the capabilities of U.S. frontier models, the report reads, continuing. The campaigns we identified targeted some of Claude's most valuable capabilities, including agentic capabilities and tool use, coding and data analysis, and logical reasoning. Now, Anthropic previously spoke out about distillation attacks in February, even calling out specific labs. Opening Eye has reported similar activity, which it attributed to DeepSeek specifically. But the campaigns detailed in Anthropic's new report are both larger and more aggressive.

4:31Now, all told, the company observed nearly 200 million exchanges linked to distillation attacks attributed to five separate campaigns. And finally, hardware crypto wallet maker Trezor is warning its customers for the second time in as many months that one of the companies it relies on was hacked, exposing the data of Trezor's customers to hackers. In a blog post this week, the hardware wallet maker said a cyber attack on Brevo, which is a marketing tech company that Trezor uses to send newsletters, allowed hackers to send around 347 ,000 phishing emails to Trezor customers, with a malicious link purporting to come from the wallet maker.

5:12Now the link, when tapped, downloads an app that asks the victim for their wallet backup password. According to Trezor, one of the email subject lines said, Critical security alert, STM32 entropy vulnerability. With a stolen wallet password, a hacker can irreversibly steal the person's funds on the public blockchain. Brevo said in an incident status post that the hackers were able to access 138 Brevo accounts to send out the mass volume of phishing messages. Brevo said that the hackers abused a flaw that meant the hackers' access was not properly scoped. The company said that the hackers' access was wrongly granted to all organizations that the hackers' accounts could reach.
