#1Anthropic's Project Glasswing: Claude Mythos Finds 10,000+ Critical Vulnerabilities

Anthropic published an update on Project Glasswing revealing that 50 partner organizations — including Apple, Microsoft, Google, Cloudflare, and the Linux Foundation — have used Claude Mythos Preview to identify more than 10,000 high- or critical-severity software vulnerabilities, many of them zero-days lurking for decades (including a 27-year-old flaw in OpenBSD). However, a major bottleneck has emerged: of 1,596 findings reported to maintainers, only 97 have been patched, exposing a gaping mismatch between AI-powered discovery and human-paced remediation. Anthropic also released Claude Security in public beta for enterprise customers.

#9Canada Rules ChatGPT Was Built on Broken Privacy Law

Canada's federal and provincial privacy commissioners jointly concluded that OpenAI violated privacy laws when training ChatGPT, citing mass scraping of personal data without consent — including health conditions, political views, and children's data — and a deceptive opt-out design that persisted until April 2024. The federal complaint was conditionally resolved after OpenAI implemented fixes, but British Columbia and Alberta refused to fully close the matter.
