To have their block validated first, an attacker would need to consistently solve for the nonce faster than anyone else in the community, such that the community believes their chain is the heaviest chain (based on the rules of the GHOST protocol we mentioned earlier). This would be inconceivable unless the attacker had greater than half of the network mining power, a state of affairs recognized as the majority 51% attack.
