DeFi Hacked Again for $292 Million, Is Even Aave No Longer Safe?

On April 19, a major DeFi security breach occurred, resulting in the loss of approximately $292 million. The attack targeted Kelp DAO’s rsETH bridge contract built on LayerZero, with 116,500 rsETH stolen. The attacker initiated the exploit using funds from Tornado Cash and manipulated the LayerZero EndpointV2 contract to transfer the assets. Kelp DAO confirmed the incident and temporarily paused rsETH contracts across multiple networks while collaborating with security experts for investigation. Initial analysis suggests the root cause was a compromised private key on the source chain, with the contract secured by only a 1/1 validator set, making it vulnerable to a single malicious transaction. The attacker used the stolen rsETH as collateral on lending platforms—including Aave, Compound, and Euler—to borrow more liquid assets like WETH, accumulating over $236 million in debt. Aave alone accounted for $196 million of this amount. In response, Aave froze its rsETH markets and stated it would explore covering potential bad debt through its Umbrella safety module, which holds around $50 million in WETH. This incident follows another large exploit earlier in April, where Drift Protocol on Solana lost $280 million. The repeated high-value attacks raise concerns about DeFi security, even affecting major protocols like Aave. Users are advised to exercise caution, diversify holdings, and limit exposure to on-chain protocols until more robust security measures are established.

From Theory to Countdown: Google Sounds the Blockchain Quantum Resistance Alarm with Zero-Knowledge Proofs

An article discusses the significant threat quantum computing poses to blockchain and classical encryption systems, triggered by Google's recent research. By optimizing Shor's algorithm, Google reduced the logical qubits required to break 256-bit elliptic curve encryption from around 6,000 to just 1,200—slashing computational costs by 20 times. This advancement sets a potential countdown, with Google estimating 2029 as the deadline for upgrading to quantum-resistant cryptography. Both Bitcoin and Ethereum face severe risks. About 25-35% of Bitcoin addresses have exposed public keys, making them vulnerable to attacks, especially during transaction processing. Ethereum’s design exposes public keys upon first use, jeopardizing its entire network if signatures aren’t updated. Historical blockchain data remains permanently available for future quantum attacks. The solution lies in adopting post-quantum cryptography (PQC). Ethereum is already implementing account abstraction and PQC-based signatures, leveraging its upgradeable architecture. Bitcoin is considering BIP-360 to introduce quantum-resistant algorithms like FALCON or CRYSTALS-Dilithium, though consensus may delay action. Notably, Google used zero-knowledge proofs to disclose this threat responsibly, aiming to prevent panic. Collaboration with Ethereum Foundation researchers suggests抗量子 (quantum resistance) could become a major narrative, aligning with crypto’s cryptographic roots.
