An AI Model Found a Coldcard Entropy Bug in Minutes, Exposing Over 1,000 BTC

A security flaw in the crypto hardware wallet's entropy generation was surfaced by an AI model in minutes — a preview of AI as an offensive security tool.

An AI model found a bug in Coldcard's entropy generation "in minutes," exposing over 1,000 BTC, according to an emergency PSA from @zackbshapiro. Entropy generation is the foundation of a hardware wallet's security — if the randomness used to generate keys is predictable, the keys are predictable, and the funds are at risk. A flaw there is about as serious as it gets for a cold-storage device.
