KelpDAO is a liquid restaking protocol built on EigenLayer, founded in 2023, that issues rsETH as a yield-bearing liquid restaking token. On April 18, 2026, attackers attributed to North Korea's Lazarus Group (TraderTraitor / UNC4899) exploited a single-point-of-failure DVN configuration on KelpDAO's LayerZero bridge to drain 116,500 rsETH worth approximately $292 million — the largest single DeFi exploit of 2026. The attack triggered $13.21 billion in DeFi TVL outflows within 48 hours and precipitated an industry-wide bailout coalition called DeFi United, which ultimately restored rsETH to full backing by May 25, 2026.

Hypurr NFTs are a 4,600-piece cat-themed NFT collection airdropped by the Hyper Foundation on September 28, 2025, to early Hyperliquid users who participated in the November 2024 Genesis Event. On the day of launch, blockchain investigator ZachXBT flagged the theft of eight Hypurr NFTs from compromised HyperEVM wallets, yielding approximately $400,000 in profit for the attacker. The collection itself is a legitimate product of the Hyper Foundation, but the incident exposed wallet security vulnerabilities in the HyperEVM ecosystem and coincided with a broader pattern of exploits across Hyperliquid-based protocols in late September 2025.
