$775K Ajna Exploit Exposes Risks in Oracle-Less DeFi Lending

Ajna Protocol, a decentralized finance (DeFi) lending platform that operates without price oracles, has fallen victim to an exploit. The attack resulted in approximately $775,000 in ETH being lost. According to reports, the attackers manipulated Ajna's internal liquidation accounting rather than using third-party price feeds. This vulnerability highlights a security risk in DeFi lending and liquidation mechanics.

The exploit impacted multiple liquidity pools, including syrupUSDC, wstETH, rETH, cbETH, WBTC, WETH/USDC, and sDAI. The attackers' use of internal liquidation accounting demonstrates that even platforms without price oracles are not immune to manipulation.

The incident serves as a reminder of the potential risks in DeFi lending and highlights the need for robust security measures. It is essential for users to be aware of these vulnerabilities and take necessary precautions to protect their assets.
