Ledger’s Response to Hardware Wallet Implants Criticized
Former Mt. Gox CEO Mark Karpelès criticized Ledger’s response to reports of tampered hardware wallets. Karpelès claimed Ledger was contacted about the risks of hardware wallets months before its latest security crisis, but he said the company did not issue public warnings. Security researcher Joe Grand alerted Ledger about a malicious implant in a Nano X wallet in August 2025, but Karpelès said Ledger acknowledged the findings but did not proactively warn customers. Ledger declined to comment on the incident, referring to its public statements on the matter.
