Solidity Forcibly Send Ether Vulnerability to a Smart Contract // Ecosystem Security from Attacks

Earlier we touched on the topic: “Improving the overall security of the ecosystem from attacks on smart contracts”. In this article, we will continue to develop this painful topic of ecosystem security. Occasionally, it is unwanted for users to be able to send Ether to a smart contract. Unfortunately for these circumstances, it’s possible to bypass a contract fallback function and forcibly send Ether. Though it seems like any transaction to the Vulnerable contract should be reverted, there are actually a couple ways to forcibly send Ether. The first method is to call the selfdestruct method on a contract with the Vulnerable contract address set as the beneficiary. This works because selfdestruct will not trigger the fallback function. Another method is to precompute a contract’s address and send Ether to the address before the contract is even deployed. Surprisingly enough, this is possible. Forcing a smart contract to hold an Ether balance can influence its internal accounting and security assumptions. There are multiple ways a smart contract can receive Ether.
