Anthropic Demonstrates Practical Key-Recovery Attack on HAWK-256

Anthropic publishes a practical key-recovery attack on HAWK-256

We have published a practical key-recovery attack on the HAWK-256 cryptographic scheme. This research demonstrates that the algorithm is vulnerable to specific attacks, rendering it unsuitable for secure applications. Our findings are accompanied by a demo repository to help the community understand the mechanics of the break and the implications for cryptographic security.

This practical attack proves that HAWK-256 is broken and should not be used for any security-critical applications.
