Post-Quantum Cipher Weakening in 60 Hours: Claude Mythos Breaks an Assumption for $100,000

This doesn’t mean today’s encryption instantly “breaks” tomorrow. But it does sharpen the urgency around post-quantum cryptography migration, continuous auditing, and defensive planning against evolving attack paths. For crypto stakeholders, the takeaway is practical: monitor how post-quantum signatures, AES, and risk mitigation strategies evolve—because the research timeline is moving fast.
Anthropic’s Claude Mythos Preview reportedly weakened a post-quantum signature scheme, halving its security in just 60 hours. The system also helped improve a 25-year-old attack against AES. Each experiment run cost about $100,000. The implication is hard to miss: it’s time to reassess how resilient current cryptographic assumptions are in the face of rapid progress. The core question remains: “Are your Bitcoins safe?”—let’s see.
