DeFiTuna was hacked for $569,601 USDC on Solana. Rootcause:The attackers created a highly illiquid TUNA/USDC pool and used it as the destination for borrowed USDC routed through Jupiter. Because the swap returned only a negligible amount of TUNA, DeFiTuna’s value calculation rounded the position’s total assets down to zero. The protocol then incorrectly treated the position as healthy, allowing the attackers to bypass the solvency check and withdraw the USDC through attacker- controlled liquidity positions. @EthSecurity1
