News linked to both this project and an event.
following the Kelp security incident, Tether's asset interoperability protocol USDT0 has disclosed details of its protocol security architecture. It stated that the system currently utilizes a proprietary DVN (Decentralized Verification Network) with message veto authority, and requires 3 independent validators, operating on different codebases, to reach a 3/3 consensus before cross-chain messages can be settled. The current verification nodes include the USDT0 proprietary DVN, LayerZero, and Canary, with future plans to expand to 4/4 and 5/5 verification mechanisms.USDT0 also stated that all multi-signature transactions must undergo multiple reviews by internal teams, external security teams, and auditing firms before signatures are submitted. The relevant contracts have been audited by firms such as Guardian and OpenZeppelin, and a $6 million bug bounty program has been launched on Immunefi.
LayerZero Labs posted on platform X, stating that the internal RPC used by LayerZero Labs had been attacked by the Lazarus Group over the past three weeks, compromising the true source of its DVN (Decentralized Verifier Network). Meanwhile, external RPC providers experienced DDoS attacks. The incident affected 0.14% of applications and approximately 0.36% of asset value. LayerZero Labs stated that assets are currently secure, and over $9 billion in funds have been bridged through the protocol since April 19.In response to the security risk, LayerZero Labs has ceased providing services for its DVN in a 1/1 configuration. Default configurations for all pathways will migrate to a multi-DVN model of at least 3/3 or 5/5 signatures. Additionally, regarding an incident from three years ago where a multi-sig holder mistakenly used a hardware wallet for personal transactions, LayerZero Labs has removed that signer and replaced the wallet, while developing a custom OneSig multi-sig system. LayerZero Labs advises developers to lock configurations to avoid reliance on default settings and plans to launch an asset management platform, Console, to enhance security monitoring.
Odaily News: Sonic Labs co-founder and Flying Tulip founder Andre Cronje posted on platform X, stating that his team is continuing to investigate the L0/rsETH incident. Preliminary reports indicate that approximately $200 million worth of rsETH was stolen, possibly due to a private key leak or configuration error. The related assets were subsequently deposited into Aave as collateral to borrow ETH (due to insufficient rsETH liquidity).Andre Cronje pointed out that the affected positions are technically still overcollateralized. However, if bad debt occurs, Aave's token mechanism and Safety Module will serve as the first line of defense to absorb the risk. Nevertheless, Aave has no mechanism to subsidize user losses, as doing so could trigger a bank run. Currently, Aave holds approximately $7 billion in ETH with an outstanding borrowing amount of around $100 million, so the overall impact of this incident is limited. Furthermore, prioritizing user liquidity, Flying Tulip has withdrawn all its ETH from Aave to its fund management wrapper contract. This action was taken because Aave's available liquidity had fallen below its set minimum threshold.
