SecondFi, a Cardano wallet service, is closing after attackers exploited a software flaw to steal 16.1 million ADA (about $2.4 million) from 374 wallets. The vulnerability allowed private keys to be derived from transaction data on the blockchain, though the Cardano network itself was not compromised. SecondFi plans to release wallet export tools and a recovery portal in August, but no timeline for fund recovery has been set. The attack was sophisticated, with possible links to North Korea's Lazarus Group, though this is unconfirmed.
