🚨 Coldcard firmware vulnerability (dating to 2021) caused weak seed entropy on affected models Attackers reconstructed the seeds offline and drained ~1,367 BTC (~$89M) from over 4,500 air-gapped wallets in late July 2026 without ever touching the devices Updating firmware alone does not secure old seeds. Generate a new seed on the latest patched firmware and carefully migrate funds.If you used Coldcard, check Coinkite’s official security advisory immediately
