Hello, this is the waveX Team. On December 6, we detected an abnormal transaction that made use of a vulnerability within part of our protocol logic. We immediately initiated a thorough investigation and mitigation procedure. We sincerely apologize for the delay in issuing this update, as we prioritized verifying the facts accurately and establishing proper measures to prevent recurrence. The impact was limited to approximately $430k after the prompt response. This issue was contained strictly within the vault-related contracts, and staking contracts and other components were not affected. waveX will fully compensate the entire loss amount. A detailed recovery plan and compensation schedule will be shared in a separate announcement shortly. Following the event, we conducted a comprehensive inspection across the protocol, which required temporarily restricting certain functionalities. The withdrawal feature for users is currently being prepared for reactivation and is scheduled to resume on Tuesday, December 16. We will provide a detailed update once it goes live. Based on the findings, we are significantly strengthening our security measures and overall defense mechanisms. We are also preparing an upgraded version of the protocol to provide a safer and more robust operating environment. All related timelines and progress updates will continue to be communicated transparently. waveX has always placed transparency and user protection as our highest priority. We are carefully coordinating internal communications to ensure that every member of our community receives clear and consistent information, and we remain fully committed to restoring your trust. Thank you for your continued support. We will return as an even safer and more resilient waveX. — waveX Team




🛡️ Exploit Analysis: Truebit Protocol (~$26M Loss) @Truebitprotocol A reminder that one missed check is all it takes. As shown in the image, the purchase function utilized SafeMath for most operations but missed the final addition step. The Vulnerability: The missing safe-add allowed an integer overflow when a large enough mint amount was passed, resulting in a token cost of zero.






We @VennBuild just discovered a critical backdoor on thousands of smart contracts leaving over $10,000,000 at risk for months Along with the help of security researchers @dedaub @pcaversaccio, the seals team @seal_911 and others, we managed to rescue the majority of funds before the attacker could make their move. This is the story of how a sophisticated attacker (cough Lazarus) put backdoors in thousands of contracts and ALMOST got away with it 🧵
