Anthropic says its Mythos model found vulnerabilities in cryptographic algorithms that secure the internet

Anthropic's AI model, Mythos, discovered vulnerabilities in cryptographic algorithms used to secure the internet. These weaknesses were found in just 60 hours at a significant cost.

What happened

Anthropic's Claude Mythos Preview model identified weaknesses in HAWK, a post-quantum signature scheme. This model was able to find the vulnerabilities in a relatively short period of time, with a significant cost of around $100,000. The findings were unexpected, as human experts had reviewed the scheme for more than two years without discovering the issues.

Why it matters

As a business owner, you rely on secure internet connections to manage your operations. These vulnerabilities highlight the potential for AI to challenge the underlying assumptions of internet security. This could lead to new risks and challenges for your business.

The takeaway

You should consider the potential impact of AI on your business's security and be prepared to adapt to new vulnerabilities and challenges as they emerge.
