Former Mt. Gox CEO Mark Karpelès stated that Ledger has been receiving reports of hardware wallets being implanted with malicious components since December 2025 but has not issued a public warning. Security researcher Joe Grand reported on March 4, 2026, that a Nano X device purchased from Lazada in Thailand had a security vulnerability, which Ledger has confirmed and is investigating internally. Additionally, a security incident disclosed on October 9 involved devices sold by CryptoBilis, an authorized dealer in Southeast Asia. Karpelès urged Ledger to proactively warn users as similar reports are increasing.
