Anthropic’s latest AI model just pulled off something impressive: it broke HAWK-256, a post-quantum cryptographic signature scheme, in roughly 60 hours using about $100,000 worth of computing power. While Bitcoin itself remains safe for now since it relies on different cryptography methods like ECDSA and Schnorr, this breakthrough shines a bright light on how fast AI is pushing the boundaries of cryptographic research.

The HAWK-256 scheme, still under evaluation by NIST for post-quantum readiness, suffered a major blow. Anthropic’s Claude Mythos AI uncovered a hidden symmetry in HAWK’s design that experts had missed, effectively cutting its security strength in half and slashing the work needed to crack it from an astronomically high 2^64 operations to a more manageable 2^38. This isn’t just a theoretical discovery it took the AI 60 hours and cost about $100,000 in computational resources to make it happen.

Bitcoin developers have long known that quantum computers could one day threaten current cryptographic standards, but this AI-driven advance accelerates the timeline. It suggests that quantum-resistant cryptography can now be tested and potentially attacked much faster and cheaper than before. The community is already working on post-quantum signature proposals, but this result adds urgency to those efforts.

No Bitcoin wallets or transactions are at risk today since HAWK-256 was never implemented on the network. However, it’s a wake-up call that the tools for breaking advanced cryptography are evolving rapidly. This comes amid other crypto market shocks, including Bitcoin’s recent price drops after Fed signals and large-scale moves by hacker groups like Lazarus.

The breakthrough also highlights a shift in how cryptographic security is tested. AI models like Anthropic’s Claude Mythos can explore complex mathematical structures and find vulnerabilities faster than traditional research teams. This will likely reshape the way future cryptographic standards are developed and audited.
