OneKey reproduces transaction replacement attack on outdated Ledger Ethereum app

OneKey said it reproduced an exploit against an older version of the Ledger app in its lab environment, which Ledger fixed in its Ethereum app 1.22.2, with no user funds lost. The in-house security team at open-source wallet provider OneKey said it successfully reproduced an exploit targeting an outdated version of Ledger’s on-device Ethereum application in a test environment.
