The vulnerability causes signatures to be generated with predictably weakened ephemeral nonces, from which an attacker can recover the signer's private key using only publicly available on-chain data. The Zilliqa team noted that protective measures are already in place to prevent further loss, and a coordinated remediation plan is being finalized. The vulnerability affects private keys used to sign native Zilliqa transactions with a Ledger device, and any account that has broadcast about five or more native transactions signed through the Zilliqa Ledger app should be considered compromised. This is because their private keys can be reconstructed from signatures already recorded on-chain, regardless of any subsequent software update. The issue is, however, confined to the Ledger app's native signing path, with EVM transactions unaffected. #Zilliqa News #Upbit
