In response to an attack, Raydium tweeted that a patch has been put in place so far to prevent further attacks. This attack has nothing to do with the escalated privileges of the program itself. The vulnerability seems to stem from a Trojan horse attack and the leakage of the private key of the liquidity pool owner account. The attacker gained access to the pool owner account and was then able to call the withdraw pnl function, which is used to collect transaction/protocol fees earned on swaps in the pool. The affected pools include SOL-USDC, SOL-USDT, RAY-USDC, RAY-USDT, RAY-SOL, stSOL-USDC, ZBC-USDC, UXP-USDC, and whETH-USDC, with a total loss of approximately $4.395 million.
