Welcome to the Tech Brew Ride Home for Friday, July 31st, 2026. I'm Brian McCullough. Today, Anthropic revealed that Claude did the breaking and entering too. Component shortages hit Apple's Outlook. Amazon jumped on accelerating AWS growth. Ashton Brenner's fund cratered 67%, but it's still up on the year. And of course, the Weekend Longreads suggestions. Here's what you missed today in the

world of tech. Well, it turns out this sort of thing might actually already be commonplace and what also might be common is that we're by and large not aware of it. Quoting Wired, Anthropic disclosed on Thursday that its AI models gained unauthorized access to the systems of three different unnamed organizations during cybersecurity testing. The company says Claude reached the

internet from within or while interacting with a third-party evaluation environment. The announcement comes more than a week after OpenAI revealed that one of its AI agents had hacked into Hugging Face during a separate cybersecurity test. The discovery came after Anthropic conducted a large-scale retrospective review of our own cybersecurity evaluations following the OpenAI incident, according to a blog post Anthropic published Thursday. The AI lab says it first identified

141,006 tests in which it determined that Claude could have obtained internet access. It then found that three different Claude models accessed the internet in evaluations run by the third-party AI testing firm Irregular and then hacked into the production infrastructure of three different organizations. Anthropic said that the incidents involved Opus 4.7, Mythos 5, and an internal research test model. The earliest incidents happened in April, meaning they likely escaped public notice for months.
