PANews April 20 news, according to CoinDesk, Kelp DAO attributes the recent approximately 290 million rsETH cross-chain bridge attack to LayerZero's default "1/1” single validation configuration and its own infrastructure being breached. The attackers compromised two servers used by LayerZero to validate cross-chain transactions and initiated a DDoS attack on a backup server, redirecting DVN traffic to the controlled nodes, thereby transferring approximately 116,500 rsETH out from Kelp's LayerZero bridge. Kelp stated that it has been in communication with LayerZero since July 2024, but has not received a clear request to change the DVN configuration, and that LayerZero's documentation and GitHub examples all use 1/1 as the default, with about 40% of connected protocols using the same structure. Kelp emphasizes that the core restaking contract was unaffected and that this attack was limited to the bridging layer.
