News linked to both this project and an event.
Blockaid disclosed on X that the Alephium TokenBridge Ethereum cross-chain bridge was attacked. The attacker compromised three out of four Guardian private keys, forged a Verified Action Approval (VAA) message, and executed the attack within approximately seven minutes, stealing roughly $815,000 worth of assets. During the attack, the attacker minted 13.76 million Wrapped ALPH tokens out of thin air—exceeding the pre-attack circulating supply by over 100%—and simultaneously unlocked and withdrew assets including USDT, USDC, WBTC, and WETH from the custody pool. As of now, the attacker’s address still holds approximately $815,000 in stolen assets and 13.76 million uncollateralized Wrapped ALPH tokens; the largest anomalous transaction involved the out-of-thin-air minting of 13.76 million Wrapped ALPH tokens.
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.
Aave stated that, per the previously disclosed technical recovery plan, the attacker’s rsETH positions on Ethereum and Arbitrum have been liquidated on Aave, and the associated collateral assets have now been transferred to the Recovery Guardian address designated by the AIP. Aave noted that this action did not impact other users, nor did it affect the Umbrella mechanism, and emphasized that this step is a critical milestone in the overall recovery roadmap, with further recovery efforts continuing as planned.
Aave has announced the completion of the liquidation of the remaining rsETH position belonging to the Kelp DAO attacker. The related collateral assets will be transferred to the Recovery Guardian multi-signature wallet managed by DeFi United, to be used for restoring rsETH reserves and compensating affected users.This liquidation is part of the recovery plan following the previous $292 million attack incident. Aave had previously passed a governance vote to temporarily adjust the rsETH oracle price in order to create bad debt in the attacker's position and trigger liquidation. The relevant parameters will be restored upon completion of the liquidation. Previously, the attacker exploited the Kelp DAO cross-chain bridge based on LayerZero to forge 116,500 unbacked rsETH and borrowed ETH from protocols such as Aave and Compound. Currently, the recovery funds managed by DeFi United have exceeded $320 million.
