Critical Ledger Bug: 7-Year Flaw Allows Private Key Reconstruction in Seconds
A massive security flaw spanning seven years has been identified in the Ledger app for Zilliqa, enabling attackers to reconstruct a private key using just five Schnorr signatures. This critical vulnerability threatens the core security of native transactions, forcing an immediate halt to network activity to prevent catastrophic fund theft.
The exploit is specifically confined to Schnorr signatures generated for non-EVM native transactions via the Zilliqa Ledger app. Because a standard transfer cannot safely mitigate the risk of key reconstruction, Zilliqa has suspended native transactions, highlighting a severe recovery challenge for users relying on hardware wallets for these specific assets.
A 7-year Ledger bug has been uncovered, allowing attackers to rebuild a private key from just five signatures in seconds. Zilliqa has suspended native transactions after discovering that roughly five affected signatures from the same private key may provide enough information to reconstruct that key, creating a recovery problem that an ordinary transfer cannot safely solve.
