  • Anthropic Unveils 'Claude Mythos', Powerful AI With Major Cyber Implications
    by BeauHD on 07/04/2026 at 10:00 pm

    "Anthropic has unveiled Claude Mythos, a new AI model capable of discovering critical vulnerabilities at scale," writes Slashdot reader wiredmikey. "It's already powering Project Glasswing, a joint effort with major tech firms to secure critical software. But the same capabilities could also accelerate offensive cyber operations." SecurityWeek reports: Mythos is not an incremental improvement but a step change in performance over Anthropic's current range of frontier models: Haiku (smallest), Sonnet (middle ground), and Opus (most powerful). Mythos sits in a fourth tier named Copybara, and Anthropic describes it as superior to any other existing AI frontier model. It incorporates the current trend in the use of AI: the modern use of agentic AI. "The powerful cyber capabilities of Claude Mythos Preview are a result of its strong agentic coding and reasoning skills... the model has the highest scores of any model yet developed on a variety of software coding tasks," notes Anthropic in a blog titled Project Glasswing -- Securing critical software for the AI era. In the last few weeks, Mythos Preview has identified thousands of zero-day vulnerabilities with many classified as critical. Several are ten or 20 years old -- the oldest found so far is a 27-years old bug in OpenBSD. Elsewhere, a 16-years old vulnerability found in video software has survived five million hits from other automated testing tools without ever being discovered. And it autonomously found and chained together several in the Linux kernel allowing an attacker to escalate from ordinary user access to complete control of the machine. [...] Anthropic is concerned that Mythos' capabilities could unleash cyberattacks too fast and too sophisticated for defenders to block. It hopes that Mythos can be used to improve cybersecurity generally before malicious actors can get access to it. To this end, the firm has announced the next stage of this preparation as Project Glasswing, powered by Mythos Preview. Given the rate of AI progress, it will not be long before such capabilities proliferate, potentially beyond actors who are committed to deploying them safely. "Project Glasswing is a starting point. No one organization can solve these cybersecurity problems alone: frontier AI developers, other software companies, security researchers, open-source maintainers, and governments across the world all have essential roles to play." Claude Mythos Preview is described as a general-purpose, unreleased frontier model from Anthropic that has nevertheless completed its training phase. The firm does not plan to make Mythos Preview generally available. The implication is that 'Preview' is a term used solely to describe the current state of Mythos and the market's readiness to receive it, and will be dropped when the firm gets closer to general release.

  • Chrome Is Finally Getting Vertical Tabs
    by BeauHD on 07/04/2026 at 9:00 pm

    Chrome is finally adding built-in vertical tabs, "which will move the tabs to the side of the browser window, making it easier to read full page titles and manage tab groups," reports TechCrunch. The company is also introducing an immersive reading mode for a distraction-free, text-focused experience. From the report: The company notes that the new vertical tabs can be enabled at any time by right-clicking on a Chrome window and selecting "Show Tabs Vertically." The company says there's no hard limit on the number of tabs that can be opened (beyond what would be limited already by the user's hardware). The vertical tabs work just as the horizontal tabs do, meaning you can have different Chrome windows with their own set of tabs or tab groups. [...] Alongside the launch of vertical tabs, Chrome is also rolling out a new Reading Mode experience, which will offer a full-page interface to make it even easier to reduce on-screen clutter to focus on the text. This will be the new default experience for Chrome users, and arrives at a time when web pages, particularly those on news sites, have become cluttered with ads and prompts to subscribe to newsletters.

  • Supreme Court Wipes Piracy Liability Verdict Against Grande Communications
    by BeauHD on 07/04/2026 at 8:00 pm

    An anonymous reader quotes a report from TorrentFreak: Following on the heels of the landmark Cox v. Sony ruling, the Supreme Court has vacated the contributory copyright infringement verdict against ISP Grande Communications, ordering the Fifth Circuit to reconsider its decision in light of the new precedent. [...] The order (PDF) effectively removes the case from the Supreme Court docket, urging the Fifth Circuit Court of Appeals to take another look at its decision in light of the new ruling. Given the similarities between the two cases, it is no surprise that the Supreme Court came to this conclusion. It is now up to the Fifth Circuit to revisit whether Grande's conduct meets the intent threshold that was established in Cox. That is a significantly higher bar than the one applied in the original verdict, which found that continuing to provide service to known infringers was enough to establish material contribution. The music companies previously said they sent over a million copyright infringement notices, but that Grande failed to terminate even a single subscriber account in response. However, without proof of active inducement, these absolute numbers carry less weight now. Whether this translates into a win for Grande on remand remains to be seen. For now, however, the original $47 million verdict is further away than ever. Read more of this story at Slashdot.

  • Testing Suggests Google's AI Overviews Tells Millions of Lies Per Hour
    by BeauHD on 07/04/2026 at 7:00 pm

    A New York Times analysis found Google's AI Overviews now answer questions correctly about 90% of the time, which might sound impressive until you realize that roughly 1 in 10 answers is wrong. "[F]or Google, that means hundreds of thousands of lies going out every minute of the day," reports Ars Technica. From the report: The Times conducted this analysis with the help of a startup called Oumi, which itself is deeply involved in developing AI models. The company used AI tools to probe AI Overviews with the SimpleQA evaluation, a common test to rank the factuality of generative models like Gemini. Released by OpenAI in 2024, SimpleQA is essentially a list of more than 4,000 questions with verifiable answers that can be fed into an AI. Oumi began running its test last year when Gemini 2.5 was still the company's best model. At the time, the benchmark showed an 85 percent accuracy rate. When the test was rerun following the Gemini 3 update, AI Overviews answered 91 percent of the questions correctly. If you extrapolate this miss rate out to all Google searches, AI Overviews is generating tens of millions of incorrect answers per day. The report includes several examples of where AI Overviews went wrong. When asked for the date on which Bob Marley's former home became a museum, AI Overviews cited three pages, two of which didn't discuss the date at all. The final one, Wikipedia, listed two contradictory years, and AI Overviews confidently chose the wrong one. The benchmark also prompts models to produce the date on which Yo Yo Ma was inducted into the classical music hall of fame. While AI Overviews cited the organization's website that listed Ma's induction, it claimed there's no such thing as the Classical Music Hall of Fame. "This study has serious holes," said Google spokesperson Ned Adriance. "It doesn't reflect what people are actually searching on Google." The search giant likes to use a test called SimpleQA Verified, which uses a smaller set of questions that have been more thoroughly vetted. Read more of this story at Slashdot.

  • Anthropic Reveals $30 Billion Run Rate, Plans To Use 3.5GW of New Google AI Chips
    by BeauHD on 07/04/2026 at 6:00 pm

    Anthropic says its annualized revenue run rate has surpassed $30 billion and disclosed plans to secure roughly 3.5 gigawatts of next-generation Google TPU compute starting in 2027. Broadcom will supply the key chips and networking gear for the effort, the company announced. The Register reports: News of the two deals emerged today in a Broadcom regulatory filing that opens with two items of news. One is a "Long Term Agreement for Broadcom to develop and supply custom Tensor Processing Units ("TPUs") for Google's future generations of TPUs." Google and Broadcom have collaborated to produce custom TPUs. Broadcom CEO Hock Tan recently shared his opinion that hyperscalers don't have the skill to create custom accelerators and predicted Broadcom's chip business will therefore win over $100 billion of revenue from AI chips in 2027 alone. Working on next-gen TPUs for Google will presumably help to make that prediction a reality. So will the second part of Broadcom's announcement: a "Supply Assurance Agreement for Broadcom to supply networking and other components to be used in Google's next-generation AI racks through up to 2031." Broadcom's filing also revealed one user of Google's next-gen TPU will be Anthropic, which starting in 2027, "will access through Broadcom approximately 3.5 gigawatts as part of the multiple gigawatts of next generation TPU-based AI compute capacity committed by Anthropic."

  • Cloudflare Fast-Tracks Post-Quantum Rollout To 2029
    by BeauHD on 07/04/2026 at 5:00 pm

    Cloudflare is accelerating its post-quantum security plans and now aims to make its entire platform fully post-quantum secure by 2029. "The updated timeline follows new developments in quantum computing research that suggest current cryptographic standards could be broken sooner than previously expected," reports SiliconANGLE. From the report: The decision by Cloudflare to move its post-quantum security roadmap forward comes after Google LLC and research from Oratomic demonstrated significant advances in algorithms and hardware capable of breaking widely used encryption methods such as RSA-2048 and elliptic curve cryptography. [...] The company said progress across three key areas -- quantum hardware, error correction and quantum algorithms -- is advancing in parallel and compounding overall capability. Improvements in areas such as neutral atom architectures and more efficient error correction are reducing the resources required to break encryption, while algorithmic advances are lowering computational complexity. [...] Cloudflare has already deployed post-quantum encryption across a large portion of its network and reports that more than half of human traffic it processes now uses post-quantum key agreement. The company plans to expand support for post-quantum authentication in 2026, followed by broader deployment across its network and products through 2028. By 2029, Cloudflare said, it expects all of its services to be fully post-quantum secure, with those services being available by default across its platform, without requiring customer action or additional cost as part of the company's commitment to security upgrades. Google said it plans to accelerate its post-quantum encryption migration target to 2029. Read more of this story at Slashdot.
