SlowMist: The root cause of the vulnerability of The R0AR is the existence of a backdoor in the contract

SlowMist issued a security alert, saying that the root cause of The R0AR vulnerability is the existence of a backdoor in the contract. During the deployment process, the R0ARStaking contract tampered with the balance (user.amount) of the specified address by directly modifying the storage slot. Subsequently, the attacker withdrew all the funds in the contract through the emergency withdrawal function.
