Unprotected Selfdestruct

Unprotected selfdestruct happens when due to missing or insufficient access controls, adversaries can self-destruct the contract. The selfdestruct(address) function removes all bytecode from the contract address and sends all ether stored to the specified address. If this specified address is also a contract, no functions (including the fallback) get called.
