    I tricked Claude into leaking your deepest, darkest secrets

    A security flaw in Claude's `web_fetch` tool, designed to prevent data exfiltration, was discovered by Ayush Paul. While `web_fetch` normally restricts navigation to user-provided or search-generated URLs, Paul found a loophole. Claude could be tricked into visiting URLs embedded in previously fetched pages. This allowed an attacker to create a honeypot website that, through a series of nested links, extracted user data like name, location, and employer. Anthropic has since patched this vulnerability.

    Google is renaming NotebookLM to Gemini Notebook

    Google is renaming its AI note-taking app, NotebookLM, to Gemini Notebook. This change comes as the app integrates more deeply with Gemini and Google Search, and will remain a standalone application. Google plans to bring notebooks to AI Mode in Search. An update will also allow Gemini Notebook to connect to a secure cloud computer for code execution, initially for Google AI Ultra and Workspace business customers.

    Sources: OpenAI researcher Miles Wang is leaving the company to launch an AI drug discovery startup, and is in talks to raise $200M at a $2B valuation (Marina Temkin/TechCrunch)

    OpenAI researcher Miles Wang is reportedly leaving to launch an AI drug discovery startup. Sources indicate he is in talks to raise $200 million at a $2 billion valuation, with Lightspeed potentially leading the round. Wang's new venture aims to develop AI models for drug discovery, possibly focusing on repurposing existing drugs. Several other OpenAI researchers are expected to join him. Wang disputed the funding figures and company description, but did not provide alternative details.

    Grok Build is open source

    xAI open-sourced their Grok Build CLI tool after community backlash over it uploading user directories, including sensitive data, to Google Cloud. xAI responded by disabling the upload feature, deleting all previously retained data, and releasing the codebase under an Apache 2.0 license to regain trust. The 844,530-line Rust codebase now emphasizes user privacy with default data retention off and local-first operation. Remnants of the upload code remain but are disabled.
