DeFiTuna Suffers Attack, Losing 569,600 USDC
CertiK published an analysis stating that the Solana ecosystem protocol DeFiTuna was attacked on July 16, with losses of approximately 569,601 USDC. The attacker first created an extremely low-liquidity TUNA/USDC pool and swapped borrowed USDC into the pool via Jupiter routing. Since only a minimal amount of TUNA was ultimately obtained, the protocol experienced rounding down during the position asset value calculation, causing the total assets to be recorded as 0, thereby incorrectly passing the health and solvency checks.
