SecondFi, a project within the Cardano ecosystem, has reportedly suffered a security breach resulting in potential losses exceeding $20 million. SlowMist founder Yu Jian noted that if addresses starting with 'addr1q' are indeed linked to the hacker, as behavior suggests, the losses could surpass 129 million ADA and other tokens. Previously, SecondFi disclosed that the security incident affected approximately 16 million ADA, attributing the issue to a flaw in their web wallet generation software.
