AI Discovers 10,000+ Zero-Days in Glasswing Cyberdefense Initiative

Anthropic revealed that Glasswing, powered by Claude Mythos Preview, autonomously identified over 10,000 high- and critical-severity zero-day vulnerabilities across critical software in its first month, with more than 50 tech partners including Microsoft, Apple, Google, and Cloudflare. Cloudflare alone found about 2,000 bugs (400 high/critical); Mozilla patched 271 Firefox vulnerabilities, while many disclosures have not been patched upstream, highlighting a severe patch-delivery bottleneck. The findings underscore the need for stronger defenses and faster triage, as Mythos-class models remain restricted to defenders, with Claude Security in public enterprise beta and industry groups rolling out supporting tools to cope with the AI-driven vulnerability deluge.

AI-Powered Exploit Unveils macOS Kernel Privilege Escalation on Apple M5 in Five Days

Researchers demonstrated the first public macOS kernel memory-corruption exploit on Apple’s M5, achieving a local root shell on macOS 26.4.1 with Memory Integrity Enforcement active. The chain starts from an unprivileged user, uses only standard system calls, and targets two known-bug classes on bare-metal M5 hardware; the bugs were found April 25 and the exploit was ready by May 1. Anthropic’s Mythos Preview aided vulnerability identification and exploit development. Apple is expected to patch; this AI-assisted attack highlights how hardware mitigations like MIE increase exploitation costs but do not fully prevent kernel exploits, with memory corruption remaining the dominant attack class across platforms.

Anthropic rolls out Opus 4.7 with stronger safeguards amid Mythos Preview buzz

Anthropic released Claude Opus 4.7, its most capable generally available model to date, boosting advanced coding tasks, image analysis, and instruction following, while adding cybersecurity safeguards; the company stresses Opus 4.7 doesn't advance the capability frontier relative to Mythos Preview, which remains more powerful but private. Opus 4.7 is intended to test safeguards ahead of broader Mythos-class releases via a Cyber Verification Program for security researchers; early testers include Intuit, Replit, Notion, Shopify, and others. Pricing remains $5 per million input tokens and $25 per million output tokens.

AI Could Turn Vulnerabilities into a Hacker Superweapon, Warn Experts

AI’s rising ability to identify and chain software vulnerabilities could empower hackers, creating a potential ‘Vulnpocalypse’ scenario. Anthropic withheld Mythos Preview over risk of misuse, while governments and major firms weigh defenses as experts predict such capabilities could spread within six to twelve months, risking outages and attacks on finance, healthcare, and critical infrastructure—even as a Hollywood-style catastrophe remains unlikely.

Mythos Preview Sparks a Security Reboot for Software

Anthropic’s Claude Mythos Preview can identify vulnerabilities across systems and autonomously develop exploits, a capability the company says will force a cybersecurity rethink. It’s being tested with Project Glasswing among a limited group of tech giants to give defenders a head start, but experts are divided: some see it as a real threat that could accelerate exploit chains and zero-click attacks, while others view it as hype. Regardless, the rollout is framed as a wake-up call to move toward secure-by-design software and machine-scale defenses rather than relying solely on patching and reaction.

Anthropic limits Mythos Preview to defense partners under Project Glasswing

Anthropic has limited Mythos Preview to select partners under Project Glasswing, granting access to more than 50 tech organizations with over $100 million in usage credits to identify and fix software vulnerabilities. The model reportedly detects thousands of high- to critical-severity bugs and can chain exploits to breach systems, prompting guarded optimism about defense benefits but raising safety concerns about a broader public release. Anthropic has briefed the U.S. government; the system card says Mythos Preview is not generally available. Many experts say results are preliminary and the potential for misuse remains a key worry.
