GM! Today’s top news: – Crypto majors are green ahead of FOMC; BTC +1.6% at $64.4k – BlackRock joins Fidelity and Goldman in support of the Clarity Act – Anthropic says Mythos broke post-quantum cryptography – Zcash activated its Ironwood upgrade, 3.8% migrated out of Orchard so far – New Robinhood meme PIPEDOG soars to $40M+ on massive volume 🔓 An AI Model Just Broke Post-Quantum Cryptography Anthropic said an unreleased version of its most powerful model, Claude Mythos Preview, found two previously unknown attacks on crypto algorithms, one of them against a scheme competing to become a U.S. federal standard. The target, HAWK, is a digital signature system that proves a transaction came from you without exposing your private key, and it was specifically designed to survive quantum computers.
NIST had advanced it to the third round of its post-quantum competition in May, where it was the last lattice-based candidate standing. Claude found a symmetry in HAWK’s math that no human had used, dropping the cost of stealing its smallest key from 2^64 operations to 2^38, roughly 67 million times less work. Patching HAWK means roughly doubling its key sizes, and as Anthropic put it, that “eliminates many of the reasons” HAWK was attractive in the first place.
