- Anthropic expands Project Glasswing to about 150 new organizations across more than 15 countries.
- Claude Mythos powers Project Glasswing, can identify thousands of zero‑day vulnerabilities over weeks, and was previewed to 50 partners—including the U.S. government—in early April.
- Anthropic says the new partners span power, water, healthcare, communications, and hardware sectors, and estimates a major breach would affect over 100 million people.
- The Financial Times reports that organizations granted access include Okta, Samsung, SK Hynix, SK Telecom, NATO, and ENISA, covering countries such as Australia, Canada, France, Germany, Italy, Switzerland, the Netherlands, Spain, Belgium, Sweden, India, Japan, New Zealand, and South Korea.
- OpenAI has rolled out a competing cybersecurity model, GPT‑5.5‑Cyber, to a large partner group, intensifying competition in AI‑driven vulnerability detection.
Why it matters: Critical infrastructure operators and governments gain AI‑driven zero‑day detection for codebases whose compromise would affect over 100 million people, while Anthropic’s expansion strengthens its market position ahead of its IPO.
