Zvi's weekly roundup references Anthropic's 'leaked Mythos model described as a step-change in cyber capabilities.' This appears alongside Nicholas Carlini using Claude Code to discover 23-year-old Linux vulnerabilities and Anthropic publishing 'Offensive Cybersecurity Time Horizons' research. Three converging signals: leaked model name, demonstrated capability, and published research framing — classic pre-launch pattern.
