Ledger Faces Fresh Scrutiny After Researcher Says Hardware Wallet Warning Came Months Earlier
Summary
Security researcher Joe Grand says he warned Ledger in March about a suspicious Ledger Nano X bought through an online marketplace in Thailand. The device reportedly contained unauthorized components that could interfere with wallet operations. Mark Karpelès has also questioned Ledger’s response to earlier tampering concerns. The reports involve hardware wallets distributed through third-party sellers, not evidence that Ledger’s core cryptography or manufacturing systems were compromised. No evidence establishes that Ledger deliberately concealed a known risk or that all reseller devices were affected. The case raises questions about warning customers and emphasizes buying from trusted channels and checking devices during setup.
