Kelp DAO refutes LayerZero's attribution of the approximately $290 million rsETH cross-chain attack

According to CoinDesk, Kelp DAO refuted LayerZero’s attribution of the approximately $290 million rsETH cross-chain attack, stating that the compromised DVN validation node was actually LayerZero’s own infrastructure, and that the 1/1 single validator configuration it used was based on LayerZero’s default settings, not an “against advice” individual choice. Kelp stated that the attack was carried out by infiltrating LayerZero’s validation node server and inducing backup nodes to fail, and that the incident only affected the cross-chain bridge layer, without impacting its core re-staking contracts. Some security researchers also pointed out that LayerZero’s documentation and default deployment code indeed use a single validation source configuration, questioning its claim of blaming Kelp. LayerZero previously stated that Kelp still used a single validator configuration despite recommendations, and announced that it would stop applying signatures to all single validator configurations, pushing the protocol layer to migrate to a multi-validator architecture.
