Episode notes
Mythos Exposed Widespread Vulnerabilities
- Anthropic's Mythos model was trained to find and avoid security bugs, and when run against widely used OS and library code it surfaced thousands of vulnerabilities.
- Anthropic shared findings privately with vendors via a Glasswing preview to let them patch issues before public release.
Validate Models Before Trusting Their Safety Claims
- Treat vendor claims of 'too dangerous to release' skeptically and expect marketing motives; validate models when possible before relying on them.
- Anthropic's secrecy limits independent assessment, so prioritize private testing and caution.
MDash Aims To Be TypeScript WordPress Successor
- Cloudflare announced MDash: a TypeScript, serverless CMS built on Astro that sandboxes plugins in isolates to address WordPress plugin insecurity.
- The sandboxing benefit depends on Cloudflare isolates, creating vendor coupling despite an MIT license.
