MetaBankA token was attacked and the exploiter was able to drain ~$14k from the pool. The loss was from the staking pool contract. The root cause is on the "award" feature but it calculated the value wrong. It uses the balance of swap but they should use the reserved value of the swap.

The attacker called CREATE2 to create a new contract and use the new contract created another contract by calling CREATE2 again. By doing that attacker could gain the "award" MBA token in sendRecommend() functions.
