Karpelès Says Ledger Mishandled Wallet Attack Warning
Former Mt. Gox chief Mark Karpelès has criticised Ledger’s response to a reported hardware wallet supply-chain attack. He alleges Ledger was warned in December 2025, before the incident came to wider attention, but placed its warning in a Ledger Academy article instead of issuing a more prominent alert. Karpelès says reports of mass-produced, self-aligning implants warranted the strongest response and has questioned how Ledger contacted affected customers. After Ledger CEO Pascal Gauthier referred to Karpelès’s Mt. Gox experience, Karpelès said he expected Ledger to learn from that failure. The claims have not been independently confirmed and do not establish a widespread vulnerability in Ledger devices. For traders, the dispute may weigh on confidence in hardware wallets and self-custody, but no direct price impact on a specific cryptocurrency is evident.
Neutral
The allegations could create short-term concern among Ledger users and prompt traders to review hardware-wallet and self-custody risks. Similar security controversies can briefly affect sentiment toward the wider crypto ecosystem, but this report does not identify a specific cryptocurrency facing a direct operational or financial impact. The claims remain unverified, and they do not establish that Ledger devices have a widespread vulnerability. As a result, there is no clear basis to expect a sustained price move in any particular coin; the direct market impact is neutral unless confirmed findings or further disclosures change that assessment.
