Ledger said a vulnerability involving an outdated Ethereum app had been patched before it could be exploited, following a demonstration by hardware-wallet maker OneKey. The demonstration showed that the older app could cause a Ledger device to sign a transaction different from the transaction displayed on its screen. Ledger rejected the characterization of the incident as a hack, saying the affected vulnerability had already been fixed. The issue relates specifically to the Ethereum app and the way transaction details were handled by an outdated version. The report was published by Decrypt on August 27, 2026. Ethereum (ETH) is the directly relevant market asset, while the incident concerns Ledger’s wallet software rather than a reported breach of the Ethereum network.
