SecondFi Winds Down After $2.6M ADA Wallet Exploit
The company said it will not resume normal operations as it develops recovery and export tools for affected users.
- On Wednesday, Cardano-based wallet SecondFi announced it will wind down operations following an exploit that stole 16.1 million ADA, worth roughly $2.4 million, from 374 wallets due to a cryptographic flaw in its transaction signing software.
- The vulnerability allowed attackers to derive private key material from transaction data visible on the blockchain; blockchain intelligence firm Groom Lake identified the perpetrator as a sophisticated, well-funded external actor.
- Indicators point to North Korea's Lazarus Group, though no attribution has been confirmed, while the Cardano network itself remained uncompromised and hardware wallet users were not affected by the breach.
- Frustrated users await recovery tools originally promised within weeks of the June exploit; responding to SecondFi's Wednesday update, one user wrote: "But many of us were told our funds could be recovered within two weeks. Now we're being asked to wait even longer."
- SecondFi plans to release wallet export tools and a zero-knowledge recovery portal in August to assist affected users, though the company has not announced any direct reimbursement plan or specified if it will compensate victims from its own funds.
