[Former Mt. Gox CEO Criticizes Ledger's Handling of Implant Incident, Claims Threat Was Known as Early as March] According to a report by Jinse Finance on October 18, citing Bitcoin News, former Mt. Gox CEO Mark Karpelès publicly criticized Ledger's handling of supply chain implant attacks on hardware wallets. Karpelès stated that Ledger was aware of such threats as early as March 2026 but failed to adequately warn customers. He noted that evidence of mass-producible, self-aligning implants should have triggered the highest level of security response, rather than burying the warning in an article on Ledger Academy. He also criticized Ledger for continuously downplaying the incident and questioned its communication with affected customers. In response to Ledger CEO Pascal Gauthier referencing Karpelès' Mt. Gox history, Karpelès retorted: 'I once believed you would learn from my failures and do better than me.'
