TL;DR: For weeks, an unauthorized Discord group had access to Mythos Preview, the model Anthropic kept guarded from the public due to its dangerous cyberoffense capabilities, Bloomberg reported on Tuesday. Anthropic framed this gatekeeping as the cost of safety—but the incident raises questions about the effectiveness of a limited rollout that was pitched as an exercise in caution.

What happened: The Discord group told Bloomberg that they got their hands on Mythos on April 7. That’s the same day Anthropic revealed Project Glasswing, giving a handpicked group of some 40-plus tech firms and other institutions exclusive access to Mythos for defensive purposes. The company says that while its goal is to eventually release Mythos-class models publicly, this specific preview model wouldn’t be generally available. Anthropic told Bloomberg that it’s “investigating” the report of unauthorized access “through one of our third-party vendor environments,” but that there’s “no evidence” it impacted Anthropic’s system.

Meanwhile, Axios also reported on Tuesday that the Cybersecurity and Infrastructure Security Agency—tasked with protecting critical tech infrastructure in the US—wasn’t given Mythos access and that it wasn’t included in Glasswing. If the limited Mythos rollout was to shore up cybersecurity, that invites scrutiny on why CISA was left out.

The opaque Mythos guest list: While Anthropic says Glasswing was intended to give cyber defenders a “head start,” we don’t have a full list of who the company decided would make the cut. Confirmed partners include many of the Big Tech names you might expect—and, despite the ongoing legal fight between Anthropic and the Trump administration, both random Discord users and the government are clearly interested in trying out the all-powerful AI. The White House is reportedly working on making a version of Mythos available to various agencies, with the National Security Agency already using it, according to Axios.

Guessing your way into the VIP section: For all the hush-hush of an exclusive cabal of sanctioned Mythos testers, the Discord group that apparently crashed the party didn’t need sophisticated exploits. They reportedly guessed the URL to reach the model based on Anthropic’s naming conventions. As for what they were doing with such a powerful AI cyber weapon: “building simple websites,” per Bloomberg. A member of the Discord server also claims that they have access to other unreleased Anthropic models.

Bottom line: OpenAI’s own restricted model, GPT-5.4-Cyber, came about a week after Mythos. But such measured rollouts don’t work if the perimeter isn’t actually secure. If some Discord users found a way to use Mythos, there’s no guarantee other groups haven’t already squeezed valuable, potentially dangerous knowledge out of a highly capable AI model—before relevant government agencies have a chance to check that everything’s secure. —WK

Your phone case is a vibe. Your screen protector could be too

Belkin's Personalized Glass Screen Protector lets you laser-etch images directly onto the glass, so your design shows up when the screen is off and disappears when you turn it on. Think of it as the screen protector equivalent of a monogrammed phone case—for people who really like to personalize their devices.

How we tested it: I've been using the Privacy version on my iPhone 17 Pro for about two weeks. The privacy filter ensures your screen is only visible when looking directly at it—handy if you're the type who texts about your most recent date in public. I originally wanted my dog's photo etched on it, but photos with busy backgrounds don't always translate cleanly, so I went with the Tech Brew logo instead. Installation was quick and intuitive, and the package included everything you need (minus instructions, so if you haven't done it before, look up a video).

The Good: The etching is genuinely cool—visible when the screen is dark or tilted, invisible head-on (two friends who saw it at the gym immediately wanted to know what it was). You can't feel the etching, so it's not a distraction. The privacy filter works without dimming your screen.

The Bad: At $54.99, this is a premium purchase—more than double Belkin's standard screen protector. The upload tool lacks a built-in photo editor.

Verdict: Signal (if customization is your thing and you're not the type to shatter a screen protector every few months). —SM

It used to be that your boss was obsessed with their golf handicap, dropping the word “synergy” into every convo, and gifting copies of The 7 Habits of Highly Effective People to new hires. But increasingly, the No. 1 fixation for corporate leaders appears to be using AI for every part of the workflow. A new report from social media strategy newsletter Link in Bio collects horror stories from marketing industry professionals on the ways their bosses abuse AI (and force them to utilize it, too).

Lowlights include: one CEO who asks Claude if a meme is funny before it can be posted to the brand’s social pages, another boss who insists every line of human-crafted copy be fed through AI for improvement, employees whose higher-up doesn’t care about their “experience or expertise” and demands Copilot summaries instead. So they write their own and make them look like Copilot chats “to get him to listen to us.”

C-suite execs are paid the big bucks in large part for their distinct vision and decision-making—and some are now outsourcing these exact skills to a tech tool that tends to choose the statistical average of answers (if it’s not hallucinating). If most of your job is rubber-stamping whatever an AI chatbot says, you might have just demoted yourself from boss to middleman. —WK
