Discovering Cryptographic Weaknesses with Claude

一句话概要

Anthropic researchers find weaknesses in cryptographic algorithms with Claude Mythos Preview

原文开头节选

Using Claude Mythos Preview, researchers at Anthropic have discovered improved ways to attack cryptographic algorithms (the mathematical methods used to keep online data private). The first attack significantly weakens HAWK, a digital signature scheme that was built for a post-quantum world. The second identifies a new way to attack round-reduced AES, the most widely used symmetric cipher. These are substantial research advances, but they do not currently affect any production systems. This post describes both findings in more detail and discusses the implications for cryptography in an age of powerful AI models.

When we launched Claude Mythos Preview, we showed it was able to autonomously find and exploit vulnerabilities in almost every piece of software we pointed it at. This included several major cryptographic libraries—shared collections of code that are used to encrypt data.

The vulnerabilities that Claude found in these cryptographic libraries 1 were due to incorrect implementation of the algorithms—that is, errors in how programmers used the algorithms in their code that …
