Did Ledger Wallet Have Tampering Alerts Months Before $86M Crypto Hack?

Key Insights: Karpelès said Ledger Wallet had received tampering reports since December 2025. Amid the crypto hack, Joe Grand reported a compromised Lazada-purchased Nano X. The October 9 disclosure involved CryptoBilis, an authorized Southeast Asian reseller. Ledger Wallet faces questions about its handling of earlier security reports following cryptocurrency thefts linked to modified hardware devices. Former Mt. Gox CEO Mark Karpelès said the manufacturer knew about suspicious devices months before the October incidents. Following the crypto hack, security researcher Joe Grand also reported finding a compromised wallet in March 2026. The October investigation later uncovered unauthorized hardware modifications in devices distributed through Southeast Asia. Reported losses initially exceeded $86 million before subsequent estimates surpassed $103 million. Ledger Wallet has since suspended regional reseller sales while investigators examine the affected products.
