Ajna Protocol, a DeFi lending platform without price oracles, suffered an exploit resulting in a loss of approximately $775,000 in ETH. The attack occurred between August 28 and 29, 2026, when the attacker manipulated the platform's internal liquidation accounting, draining funds from multiple liquidity pools. The syrupUSDC pool was hit hardest, losing around $173,700. Ajna's design philosophy, which eliminates external price feeds and governance, was exploited, raising concerns about its security assumptions. Monitoring firm Defimon detected the attack preparations over an hour before the exploit began but could not prevent it. Following the incident, Ajna's total value locked (TVL) plummeted to $246,880, reflecting a 71.3% decline. The incident highlights vulnerabilities in DeFi protocols that do not utilize price oracles. The current status of the protocol remains uncertain as users are advised to withdraw their funds.

Key Points: • Ajna Protocol lost approximately $775,000 due to an exploit manipulating internal liquidation logic. • The attack targeted multiple liquidity pools, with syrupUSDC suffering the largest loss. • Defimon detected the attack preparations but could not secure the protocol in time.
