Project Eleven co-founder warns AI is finding cracks in post-quantum cryptography

Conor Deegan says AI models exposed mathematical flaws in HAWK and Classic McEliece, two schemes built to survive quantum computers The cryptography designed to protect us from quantum computers just ran into a different kind of machine. According to Conor Deegan, co-founder of Project Eleven, AI models have found exploitable mathematical flaws in two post-quantum schemes: HAWK and Classic McEliece. No quantum computer was required. The weaknesses were in the math itself, and AI spotted them. Deegan made the comments on October 19, 2026. The timing matters because the industry has spent years preparing for a quantum threat. Now it may have to plan for a much faster cryptanalyst that is already here.
