Back in 2021 someone asked Coldcard "what's a retirement attack?" Their answer: a bug in entropy generation, just sitting there for someone to cash in later. Entropy is basically the randomness behind your seed phrase. Weak entropy means it's not really a secret anymore, it's just a search space. Fast forward to 2026: millions drained from wallets running on a fraction of the entropy they were supposed to have. Countless people lost their life savings, their Plan B. The tweet aged like a prophecy. AI now makes probing for security weaknesses easier. Fortunately, the same tool is available for defenders. They just have to remember to use it.(Lark Davis)
