Can a hacker change data of a smart sontract without call contract function

Question

Is there a possibility that a hacker can update or alter the content of the smart contract.??.

Answer 1

A contract's content cannot be changed internally. Only the smart contract itself is allowed to modify the storage. A contract's storage can only be changed via a transaction. I don't think there can be a possibility that the content of the contract can be changed illegally.
