OneKey has successfully replicated a transaction replacement attack exploit on an outdated version of the Ledger Ethereum application. According to CoinTelegraph, this vulnerability was addressed by Ledger in the release of Ethereum app version 1.22.2, ensuring that no user funds were compromised.
The exploit was reproduced in OneKey's controlled lab environment, confirming that the issue only affected older versions of the Ledger app. Ledger's prompt patching with version 1.22.2 has mitigated the risk, providing reassurance to users of the hardware wallet.
For Japanese investors and traders, this incident underscores the importance of keeping crypto wallet software up to date, particularly in a market where hardware wallets like Ledger are widely used to secure digital assets.
