Ledger Faces Scrutiny Over Earlier Warnings
Security researcher Joe Grand has accused Ledger of not promptly warning about signs of physically modified Ledger Nano X devices, which contained unauthorized components that could interfere with sensitive wallet operations. The dispute centers around communications and product distribution, not the core cryptography of Ledger’s devices. Ledger has denied any compromise of its manufacturing or cryptographic systems, but the incident has raised questions about how Ledger handled earlier warnings about tampered devices.
