SecondFi says wallet attack may be linked to Lazarus indicators, targets August 2026 launch for recovery tool

SecondFi, a Cardano wallet service provider, has released an update on its security incident investigation, saying forensic work commissioned by EMURGO and carried out by independent blockchain forensics firm Groom Lake identified two separate attackers. According to the update, the primary attacker used advanced techniques and showed some overlap with known indicators tied to North Korea’s Lazarus Group, though the assessment is still ongoing. A second attacker appeared to operate independently and used different wallet addresses. SecondFi said the root cause was a cryptographic flaw in its wallet software during per-transaction signature generation. In theory, that flaw could allow an attacker to derive private key material for affected wallets from publicly available on-chain data. The company added that the vulnerable code had previously been published without authorization to a public GitHub repository, and said it is continuing to assess the situation while cooperating with authorities. SecondFi said the flaw has now been fixed and that wallets created with the patched version are not affected. The company also said it will shut down both SecondFi and Yoroi wallets, roll out a wallet export function before then, and release a zero-knowledge-proof-based asset recovery tool in August 2026.
