A random-number flaw in Coinkite's Coldcard wallets fueled an $88 million Bitcoin heist as OpenAI teased Astra, a model whose math breakthroughs sharpen fears of AI-driven cryptanalysis.
Latest developments: BleepingComputer raised the tally to roughly $88.6 million and pinned the losses on the flawed random number generator, which produced predictable seeds across thousands of wallets.
Coinkite's Coldcard, a Bitcoin-only hardware wallet from the Canadian maker, shipped a March 2021 firmware integration error that routed seed generation to a deterministic software pseudorandom number generator, letting attackers predict private keys and empty wallets; Galaxy Research mapped a July 30 sweep that drained 1,196 addresses in 41 minutes, and owners who generated seeds on affected firmware should move funds to a freshly seeded wallet.
