Several dozen organizations, including JPMorgan Chase, Bank of America and Goldman Sachs, received access to Anthropic's Mythos under Project Glasswing to study the model's dangers.
That limited rollout left many smaller and international lenders without the tool, prompting questions about whether cybersecurity vulnerabilities identified by insiders can be shared outside the program.
The access gap has added a new concern to broader alarm over Mythos's power, extending unease from corporate boardrooms to political circles.
The episode highlights how uneven access to frontier AI can shape who sees emerging cyber risks first—and who is left waiting for warnings.
Can we trust AI creators to secure the world when their tools are also deemed national security risks?
With AI finding flaws faster than humans can patch them, is our digital infrastructure now indefensible?
As AI creates a cyber 'poverty line', how can smaller firms survive the coming 'vulnerability storm'?
Mythos AI Unleashed: How Anthropic’s Model Discovered Over 10,000 Banking Vulnerabilities and Sparked a Global Cybersecurity Reckoning
Overview
Anthropic's Mythos AI has rapidly transformed cybersecurity in the banking sector by autonomously discovering and exploiting zero-day vulnerabilities at an unprecedented scale. This disruptive capability puts immense pressure on banks, especially those with aging technology, forcing major financial institutions to analyze Mythos AI's findings and share critical insights with smaller banks. As a result, smaller institutions are working proactively to strengthen their defenses. The dual nature of Mythos AI—offering both powerful defensive tools and new risks—has led to increased collaboration and a heightened focus on adapting security strategies across the industry.
