SecondFi, a Cardano ecosystem wallet provider, said about 16.1 million ADA—worth roughly $2.6 million—was stolen after a cryptographic weakness in its wallet software was exploited. The breach impacted 374 wallets, and the company plans to gradually phase out both its SecondFi and Yoroi wallet services.
SecondFi said an independent probe by blockchain intelligence firm Groom Lake concluded the attacker was a sophisticated external actor. The investigation flagged indicators that could be associated with North Korea's Lazarus Group, though no attribution has been confirmed.
To support affected users, SecondFi is building a zero-knowledge proof-based recovery tool aimed at enabling asset recovery while limiting the amount of information users must disclose. The tool remains in testing and is slated for third-party audits ahead of a planned August release.
SecondFi is also preparing a wallet export function to help users migrate funds to other services. The company has not outlined any compensation plan and has not said whether it will use its own funds to reimburse users.
