Former Mt. Gox CEO Comes to Ledger’s Rescue

Former Mt. Gox CEO Mark Karpelès has developed a low-cost device that can detect hidden spy implants in hardware wallets without opening them, responding to recent security concerns around Ledger devices. The tool targets supply-chain tampering, a persistent worry for self-custody users after high-profile wallet exploits. The story is a niche security development with no direct price catalyst, though it could modestly support confidence in hardware-wallet self-custody.
