A Bitcoin holder who forgot their wallet password while high in college has finally regained access to nearly $400,000 worth of cryptocurrency with help from Anthropic's Claude AI. After 11 years of failed attempts and 3.5 trillion password combinations, the AI discovered an old wallet backup file and identified a critical bug that had prevented recovery all along.
Anthropic has claimed the top spot in business AI adoption for the first time, with 34.4% of companies now paying for its services compared to OpenAI's 32.3%, according to Ramp's May 2026 AI Index. The shift marks a dramatic reversal after Anthropic quadrupled its business customer base over the past year while OpenAI's share declined, driven largely by Claude Code's success among technical users.
The UK AI Security Institute reports Anthropic Mythos is advancing faster than anticipated, with capability doubling times shrinking from 8 months to around 4 months. The model now completes previously unsolved cybersecurity challenges and can create functional exploits from software vulnerabilities, raising concerns about AI-driven cyberattacks targeting critical infrastructure within months.
Anthropic unveiled Claude for Small Business, a suite of AI-powered workflows and integrations designed for the 36 million small businesses that have lagged in AI adoption. The new offering connects Claude to QuickBooks, PayPal, HubSpot, and other platforms to automate tasks like payroll planning and invoice chasing. However, Pro and Max plan users should note that their business data may be used to train Claude by default.
The European Central Bank's Frank Elderson is urging euro area banks to immediately prepare for potential cyberattacks powered by Anthropic's Mythos AI model. Despite lacking access to the tool, Elderson emphasized that inaction is not an option as banks must brace for increasingly aggressive AI-driven cyber warfare. Large U.S. banks with early Mythos access are already rushing to fix data system vulnerabilities.
AI design tools like Claude Design are accelerating typography workflows, but they're also pushing brands toward generic, safe defaults. As 82% of creatives cite typography as critical to decision-making, business leaders face a strategic choice: invest in distinctive typographic systems or risk blending into an increasingly homogeneous marketplace where AI-driven design creates convergence rather than differentiation.
Anthropic is meeting with the House Homeland Security Committee in a closed-door briefing to discuss Mythos, its most advanced cybersecurity AI model. The system can identify decades-old software vulnerabilities but also raises concerns about potential exploitation by hackers. This marks the second such briefing in recent weeks as Washington grapples with AI safety risks.
Anthropic has acquired Stainless, the SDK generation startup used by OpenAI, Google, and Cloudflare, for over $300 million. The deal removes a critical infrastructure supplier from competitors' hands as Anthropic winds down all hosted Stainless products by September 2026, forcing rivals to find alternative tooling solutions.
Japan's three largest banks—MUFG, Mizuho, and Sumitomo Mitsui—will gain access to Anthropic's vulnerability-hunting AI model Mythos by the end of May. This marks the first Japanese entry to the restricted rollout, which has uncovered thousands of zero-day vulnerabilities across major operating systems and browsers. Japan is establishing a public-private working group to address the cybersecurity risks posed by this powerful AI model.
Anthropic announced Tuesday it's launching 12 new legal plugins and over 20 MCP connectors for Claude, expanding its AI tools for law firms. The release integrates Claude with Thomson Reuters, DocuSign, and Harvey, positioning Anthropic to compete in the rapidly growing legal AI sector where startups have raised hundreds of millions in recent months.
Japan's Prime Minister Sanae Takaichi has ordered a cabinet-level cybersecurity review to defend against Anthropic's Mythos AI model. The move comes as officials warn that the bug-hunting AI could enable faster, more sophisticated cyberattacks on critical infrastructure. Japan is now coordinating with Western allies to prevent weaponization of advanced AI models.
OpenAI unveiled Daybreak, a cybersecurity initiative that uses AI models including GPT-5.5 and Codex Security to find and patch software vulnerabilities. The launch positions OpenAI directly against Anthropic's Project Glasswing and Claude Mythos, as both AI giants race to tilt the balance in favor of defenders. Major partners including Cisco, Cloudflare, and CrowdStrike are already integrating the capabilities.
Major AI providers including GitHub, OpenAI, and Anthropic are abandoning flat subscription models for usage-based pricing, driving AI costs higher than human capital in some cases. Researchers face financial burdens while enterprises burn through annual budgets in months, prompting some to hire people instead of deploying AI tools.
Anthropic will present findings from its Mythos AI model to the Financial Stability Board, chaired by Bank of England Governor Andrew Bailey. The model has identified thousands of high-severity vulnerabilities across major operating systems and browsers, succeeding in developing exploits in over 83% of cases during testing. Regulators warn of significant disruption ahead as financial institutions race to patch flaws in legacy technology systems.
Security researchers have uncovered an active cybercrime campaign targeting Mac users through fraudulent Google Ads and Claude.ai's legitimate shared chat feature. Attackers are creating fake installation guides that trick users into running Terminal commands, silently downloading infostealing malware onto their devices. The campaign exploits trust in sponsored search results and authentic Claude URLs.
