Cardano-based wallet provider SecondFi identified the root cause of a recent breach as a flaw at the address level, which allowed attackers to drain funds from 374 affected addresses. Following its investigation, the platform reported securing 129 million ADA, suggesting it managed to protect or recover a significant portion of user assets tied to the incident. The exploit highlights ongoing security risks facing crypto wallet infrastructure, where vulnerabilities in how addresses are generated or managed can expose user funds to theft. SecondFi's tracing of the issue to a specific technical weakness points to a targeted attack vector rather than a broad protocol failure on the Cardano network. The full scale of losses and the status of affected users remain key questions as the platform continues its response and works to address the underlying vulnerability.
