Coldcard Wallet Hack and JST Spot Data
JUST (JST)
Finance.yahoo.com reports that hackers stole $130 million in Bitcoin from Coldcard hardware wallets due to weak random number generators in the devices. The breach occurred in late July and early August, allowing attackers to derive private keys and steal funds remotely. This event undermines trust in self-custody and suggests a shift toward institutional solutions like spot Bitcoin ETFs. The incident highlights that controlling private keys is insufficient if the seed phrase generation is flawed. Coinkite has released new firmware to address the security issue, but rebuilding market confidence remains difficult. The loss of $130 million serves as a significant warning for investors relying on specific hardware wallets. This development challenges the core Bitcoin philosophy of individual financial empowerment through self-custody.
