Wu said that LayerZero announced that on April 18, 2026, KelpDAO was attacked, resulting in a loss of approximately $290 million. The initial attribution suspects North Korea's DPRK Lazarus Group (TraderTraitor). The attack involved contaminating the downstream RPC used by DVN and coordinating a DDoS attack to trigger a failover, causing DVN to confirm that no transactions occurred and that no protocol or key vulnerabilities were exploited. The incident was caused by KelpDAO's use of a 1/1 single DVN configuration, leading to a single point of failure. The impact was limited to rsETH, with no spread to other assets or applications. The affected RPC has been replaced, and LayerZero Labs' DVN has resumed operation.
