SecondFi Cardano wallet hacked, $2.4M stolen, losses may exceed $20M; users urged to move funds immediately

SecondFi, formerly Yoroi, suffered a critical security breach on June 23 due to a flaw in its wallet key generation, compromising 178 wallets and resulting in confirmed losses of about 16 million ADA ($2.4 million). Security firm SlowMist warns total damages could exceed $20 million, affecting up to 129 million ADA tokens. The platform has suspended operations and advised its over one million users to transfer assets to new wallets immediately. Fraudsters are exploiting the situation by impersonating SecondFi representatives, increasing risks for users. The incident raises serious concerns about Cardano's ecosystem security and Emurgo's role in addressing compensation remains unclear.
