SecondFi exploit tied to wallet-generation flaw exposes Cardano users, losses estimated at $2.4 million

SecondFi reported a wallet-generation vulnerability on 23 June that exposed private keys used to create Cardano (ADA) wallets, opening a path for unauthorized access. The exploit was linked to losses of roughly 16 million ADA, worth about $2.4 million. Further investigation suggested SecondFi may have lost up to 129 million ADA after other tokens and NFTs were also exposed. The incident has fueled broader concerns about user trust in the platform.
