Karpelès: Ledger’s Early Implant Warnings Needed Faster Action

French hardware wallet vendor Ledger disclosed that some customer losses tied to wallets sold through a Southeast Asia reseller involved devices containing an unauthorized hardware implant. The episode has reignited scrutiny of how tampered units reach end users—and whether manufacturers act quickly enough after receiving early warning signs. According to Mark Karpelès, former CEO of Mt. Gox, he was told of tampered Ledger devices months before Ledger’s latest security crisis surfaced.
